This Manual of Style, often abbreviated MoS, is a style guide to make Wikipedia easier to read. One way of presenting information is often just as good as another, but consistency promotes professionalism, simplicity and greater cohesion in Wikipedia articles. An overriding principle is that style and formatting should be applied consistently throughout an article, unless there is a good reason to do otherwise (except in direct quotations, where the original text is generally preserved).

If the Manual of Style does not specify a preferred usage, discuss your issues on the talk page of this manual. The menu to the right contains links to Manual of Style pages that explore topics in greater detail.

It is inappropriate for an editor to change an article from one style to another unless there is a substantial reason to do so; for example, it is unacceptable to change from American to British spelling unless the article concerns a British topic. Edit warring over optional styles is unacceptable. If an article has been stable in a given style, it should not be converted without a reason that goes beyond mere choice of style. When it is unclear whether an article has been stable, defer to the style used by the first major contributor.^[1]

Article titles, headings and sections

Article titles

This guidance applies to the titles of Wikipedia articles, not to the titles of external articles that are cited.

Article titles should conform to Naming conventions, including Use English.
Titles are generally nouns or noun phrases (Effects of the wild, not About the effects of the wild).
Titles should be short—preferably fewer than ten words.
The initial letter of a title is capitalized (except in very rare cases, such as eBay). Otherwise capital letters are used only where implied by normal capitalization rules (Funding of UNESCO projects, not Funding of UNESCO Projects).
A, an and the are normally avoided as the first word (Economy of the Second Empire, not The economy of the Second Empire), unless part of a proper noun (The Hague).
Special characters such as the slash (/), plus sign (+), braces ({ }) and square brackets ([ ]) are avoided; the ampersand (&) is replaced by and, unless it is part of a formal name.

This guidance also applies to Section headings below.

First sentences

If possible, an article title is the subject of the first sentence of the article; for example, "The Manual of Style is a style guide" instead of "This style guide is known as ...". If the article title is an important term, it appears as early as possible. The first (and only the first) appearance of the title is in boldface, including its abbreviation in parentheses, if given. Equivalent names may follow, and may or may not be in boldface. Items in boldface are not linked, and boldface is not used subsequently in the first paragraph. For example: "Vienna (German: Wien [viːn], see also its other names) is the capital of Austria and one of that country's nine states."
If the topic of an article has no name and the title is merely descriptive—such as Electrical characteristics of a dynamic loudspeaker—the title does not need to appear verbatim in the main text; if it does, it is not in boldface.
The normal rules for italics are followed in choosing whether to put part or all of the title in italics ("Tattoo You is an album by The Rolling Stones, released in 1981").
If the topic of the article may be unfamiliar to some readers, establish a context. For example, instead of "A trusted third party is an entity that facilitates interactions between two parties who both trust the third party", write "In cryptography, a trusted third party is an entity that facilitates interactions between two parties who both trust the third party". The context in this example is that the topic covered by the article is the use of that notion in the field of cryptography.

Section headings

တူဝ်ယေႃႈ: WP:HEAD WP:MOSHEAD

SEE ALSO the guidance in Article titles above, which also applies to section headings.
Section names should preferably be unique within a page; this applies even for the names of subsections. The disadvantages of duplication are that:
- after editing, the display can arrive at the wrong section; see also below; and
- the automatic edit summary on editing a section with a non-unique name is ambiguous.
Section names should not normally contain links.
Section names should not explicitly refer to the subject of the article, or to higher-level headings, unless doing so is shorter or clearer. For example, Early life is preferable to His early life when His means the subject of the article; headings can be assumed to be about the subject unless otherwise indicated.
Unspaced multiple equal signs are the style markup for headings. The triple apostrophes ( ''' ) that make words appear in boldface are not used in headings. Nest headings correctly. The hierarchy is as follows:
- the automatically generated top-level heading of a page is H1, which gives the article title;
- primary headings are then ==H2==, followed by ===H3===, ====H4====, and so on.
Spaces between the == and the heading text are optional (==H2== versus == H2 ==). These extra spaces will not affect the appearance of the heading, except in the edit window.
A blank line below the heading is optional. If there are no blank lines above the heading, one line should be added, for readability in the edit window. Only two or more blank lines above or below will change the public appearance of the page by adding more white space.

Section management

Headings provide an overview in the table of contents and allow readers to navigate through the text more easily.
Change a heading only after careful consideration, because this will break section links to it within the same article and from other articles. If changing a heading, try to locate and fix broken links; for example, searching for wikipedia "section management" will yield links to the current section.
When linking to a section, as a courtesy, go to that article's section and leave an editor's note to remind others that the title is linked. List the names of the linking articles, so that if the title is altered, others can fix the links without having to perform exhaustive searches. For example:
==Evolutionary implications== .
As well, consider a preemptive measure to minimize link corruption when the text of a heading changes by inserting an {{anchor}} with an alternative name by which to link to that heading section. For example:
==Evolutionary implications{{anchors | RDawkins | DDennett}}== .
When referring to a section without linking, italicize the section name (italicize the actual section name only if it otherwise requires italics, such as the title of a book); for example, the current section is called Section management.
The standard order for optional appendix sections at the end of an article is See also, Notes (or Footnotes), References, Further reading (or Bibliography), and External links; the order of Notes and References can be reversed. See also is an exception to the point above that wording comprises nouns and noun phrases. For information on these optional sections, see Wikipedia:Layout#Standard appendices and descriptions and Wikipedia:Citing sources.

Capital letters

There are differences between the major varieties of English in the use of capitals (uppercase letters). Where this is an issue, the rules of the cultural and linguistic context apply. As for spelling, consistency is maintained within an article.

Within articles and other wiki pages, capitals are not used for emphasis. Where wording cannot provide the emphasis, italics are used.

Incorrect:	Contrary to popular belief, aardvarks are Not the same as anteaters.
Incorrect:	Contrary to popular belief, aardvarks are NOT the same as anteaters.
Correct:	Contrary to popular belief, aardvarks are not the same as anteaters.

Titles

When used as titles (that is, followed by a name), items such as president, king and emperor start with a capital letter: President Clinton, not president Clinton. The formal name of an office is treated as a proper noun: Hirohito was Emperor of Japan and Louis XVI was King of France (where Emperor of Japan and King of France, respectively, are titles). Royal styles are capitalized: Her Majesty and His Highness; exceptions may apply for particular offices.
When used generically, such items are in lower case: De Gaulle was a French president and Louis XVI was a French king. Similarly, Three prime ministers attended the conference, but, The British Prime Minister is Gordon Brown.
For the use of titles and honorifics in biographical articles, see Honorific prefixes.

Religions, deities, philosophies, doctrines and their adherents

Religions, sects and churches and their followers (in noun or adjective form) start with a capital letter. Generally the is not capitalized before such names (the Shī'a, not The Shī'a). (But see also the style guide and naming convention for the Latter Day Saint movement.)
Scriptures (religious texts) are capitalized but often not italicized (for example, the names of the Qur’an, the Talmud, the Granth Sahib, and the Bible). When the is used, it is not capitalized. Some derived adjectives are capitalized by convention, some are not (normally biblical but Koranic, for example); if unsure, check a dictionary appropriate to the topic, and be consistent within an article.
Honorifics for deities, including proper nouns and titles, start with a capital letter (God, Allah, the Lord, the Supreme Being, the Great Spirit); the is not capitalized. The same is true when referring to major religious figures and figures from mythology by titles or terms of respect (the Prophet, the Messiah, the Virgin, a Muse). Common nouns denoting deities or religious figures are not capitalized; thus the Romans worshipped many gods, many Anglo-Saxons worshipped the god Wotan, Jesus and Muhammad are both considered prophets in Islam, biblical scholars dispute whether Mary was a virgin for her entire life, and her husband was her muse.
Pronouns and possessives referring to figures of veneration are not capitalized in Wikipedia articles, even when they traditionally are in a religion's scriptures. They are left capitalized when directly quoting scriptures or any other texts that capitalize them.
Broad categories of mythical or legendary creatures do not start with uppercase capital letters (elf, fairy, nymph, unicorn, angel), although in derived works of fantasy, such as the novels of J.R.R. Tolkien and real-time strategy video games, initial capitals are sometimes used to indicate that the beings are regarded as cultures or races in their fictional universes. Names or titles of individual creatures are capitalized (the Minotaur, the Pegasus) as are those of groups whose name and membership are fixed (the Cherubim, the Magi or the Three Wise Men). As with terms for deities, generalized references are not capitalized (cherub-like, the priests of this sect were called magi by some, several wise men were consulted).
Spiritual or religious events are likewise capitalized only when they are terms referring to specific incidents or periods (the Great Flood, the Exodus, but annual flooding or an exodus of refugees).
Philosophies, theories and doctrines do not begin with a capital letter unless the name derives from a proper noun (capitalism versus Marxism) or has become a proper noun (lowercase republican refers to a system of political thought; uppercase Republican refers to one of several specific political parties or ideologies, such as the US Republican Party or Irish Republicanism). Physical and natural laws and parodies of them are capitalized (the Second Law of Thermodynamics, the Theory of Special Relativity, Murphy's Law; but an expert on gravity and relativity, thermodynamic properties, Murphy's famous mock-law). Doctrinal topics or canonical religious ideas (as distinguished from specific events) that may be traditionally capitalized within a faith are given in lower case in Wikipedia, such as virgin birth, original sin or transubstantiation.
Platonic or transcendent ideals are capitalized (Good, Truth), but only within the context of philosophical doctrine; used more broadly, they are lower-case (Superman represents American ideals of truth and justice). Personifications represented in art, such as a statue of the figure Justice, are capitalized.

Calendar items

Months, days of the week, and holidays start with a capital letter: June, Monday, the Fourth of July (when referring to the U.S. Independence Day, otherwise July 4 or 4 July).
Seasons, in almost all instances, are lowercase: This summer was very hot; The winter solstice occurs about December 22; I've got spring fever. When personified, season names may function as proper nouns, and they should then be capitalized: I think Spring is showing her colors; Old Man Winter.

Animals, plants, and other organisms

Scientific names for genera and species are italicized, with a capital initial letter for the genus but no capital for the species; for more specific guidelines for article titles, see Wikipedia:WikiProject Tree of Life#Article titles. For example, the tulip tree is Liriodendron tulipifera, and humans are Homo sapiens. Taxonomic groups higher than genus are given with an initial capital and are not in italics; for example, gulls are in the family Laridae, and we are in the family Hominidae.

Common (vernacular) names of flora and fauna should be written in lower case—for example, oak or lion. There are a limited number of exceptions to this:

Where the common name contains a proper noun, such as the name of a person or place, that proper noun should be capitalized; for example, The Amur tiger may have a range of over 500 square kilometres, or The Roosevelt elk is a subspecies of Cervus canadensis.
For specific groups of organisms, there are specific rules of capitalization based on current and historic usage among those who study the organisms. For example, official common names of birds are normally capitalized.
In a very few cases, a set of officially established common names are recognized only within a country or a geographic region. Those common names may be capitalized according to local custom but it should be understood that not all editors will have access to the references needed to support these names; in such cases, using the general recommendation is also acceptable.

In any case, a redirect from an alternative capitalization should be created where it is used in an article title.

Celestial bodies

Sun, earth and moon are not capitalized generally (The sun was peeking over the mountain top). They may be proper nouns in an astronomical context but only when referring to specific celestial bodies (our Sun, Earth and Moon): so The Moon orbits the Earth, but Jupiter's moon Io.
Other planets and stars are proper nouns and start with a capital letter: The planet Mars can be seen tonight in the constellation Gemini, near the star Pollux. Where a name has multiple words, it is treated like other proper nouns where each leading letter is capitalized: Alpha Centauri and not Alpha centauri.

Directions and regions

Directions such as north are not proper nouns and are therefore lowercase. The same is true for their related forms: someone might call a road that leads north a northern road, compared with the Great North Road. Composite directions may or may not be hyphenated (northeast and north-east, Southeast Asia and South-East Asia), depending on the general style adopted in the article.
Regions that are proper nouns, including widely known expressions such as Southern California, start with a capital letter. Follow the same convention for related forms: a person from the Southern United States is a Southerner. Regions of uncertain proper-noun status are assumed not to have attained it.

Institutions

Proper names of institutions (for example, the University of Sydney, NewYork-Presbyterian Hospital, George Brown College) are proper nouns and require capitalization. Where a title starts with the, it typically starts with lowercase t when the title occurs in the middle of a sentence: a degree from the University of Sydney.
Generic words for institutions (university, college, hospital, high school) require no capitalization:

Incorrect	(generic):	The University offers programs in arts and sciences.
Correct	(generic):	The university offers ...
Correct	(title):	The University of Delhi offers ...

Acronyms and abbreviations

Write out both the full version and the abbreviation at first occurrence: When using acronyms, initialisms and other abbreviations, it should be remembered that readers are not necessarily familiar with their meanings. Good practice is to name an item in full on its first occurrence, followed by the abbreviated form in parentheses. For example, The New Democratic Party (NDP) won the 1990 Ontario election with a significant majority (first mention of New Democratic Party in the article), and The NDP quickly became unpopular with the voters (subsequent mention).; Initial capitals are not used in the full name of an item just because capitals are used in the abbreviation.

Incorrect	(not a name):	We used Digital Scanning (DS) technology
Correct:		We used digital scanning (DS) technology
Correct	(name):	produced by the British Broadcasting Corporation (BBC)

If the full term is already in parentheses, use a comma and or to indicate the abbreviation; for example, They first debated the issue in 1992 (at a convention of the New Democratic Party, or NDP).
Plural and possessive forms: Acronyms and initialisms are pluralized by adding -s or -es as with any other nouns (They produced three CD-ROMs in the first year; The laptops were produced with three different BIOSes in 2006). As with other nouns, no apostrophe is used unless the form is a possessive.
Periods (full stops) and spaces: Acronyms and initialisms are generally not separated by full stops (periods) or blank spaces (GNP, NORAD, OBE, GmbH); many periods and spaces that were traditionally required have now dropped out of usage (PhD is preferred over Ph.D. and Ph. D.). Periods are not used in units of measurement (see Wikipedia:Manual of Style (dates and numbers) for more information).

Truncated (Hon. for Honorable), compressed (cmte. for committee) and contracted (Dr. for Doctor) abbreviations may or may not be closed with a period. A consistent style should be maintained within an article. A period is much more usual in American usage (Dr. Smith of 42 St. Joseph St.); and no period is commonly preferred in British and other usage (Dr Smith of 42 St Joseph St, though one or other "St" might take a period, in such a case). Some British and other authorities prefer to drop the period from truncated and compressed abbreviations generally (XYZ Corp, ABC Ltd), a practice also favored in science writing. Regardless of punctuation, such abbreviations are spaced if multi-word (op. cit. or op cit, not op.cit. or opcit).

US and U.S.: In American English, U.S. is the standard abbreviation for United States; US is becoming more common and is standard in other national forms of English. In longer abbreviations incorporating the country's initials (USN, USAF), periods are not used. When the United States is mentioned along with one or more other countries in the same sentence, U.S. or US can be too informal, and many editors avoid it especially at first mention of the country (France and the United States, not France and the U.S.). In a given article, if the abbreviated form of the United States appears predominantly alongside other abbreviated country names, for consistency it is preferable to avoid periods throughout; never add periods to the other abbreviations (the US, the UK and the PRC, not the U.S., the U.K. and the P.R.C.). The spaced U. S. is never used, nor is the archaic U.S. of A., except in quoted materials. U.S.A. and USA are not used unless quoted or as part of a proper name (Team USA).

Do not use unwarranted abbreviations

The use of abbreviations should be avoided when they would be confusing to the reader, interrupt the flow, or appear informal or lazy. For example, approx. for approximate or approximately should generally not be used, although it may be useful for reducing the width of an infobox or a table of data, or in a technical passage in which the term occurs many times.

See also Wikipedia:Manual of Style (dates and numbers) for when to abbreviate units of measurement.

Do not invent abbreviations or acronyms: Generally avoid the making up of new abbreviations, especially acronyms. For example, while it is reasonable to provide World Union of Billiards as a translation of Union Mondiale de Billard, the former is not the organization's name, and it does not use the acronym or initialism WUB; when referring to it in short form, use the official abbreviation UMB. In a wide table of international economic data, it might be desirable to abbreviate a United States gross national product heading; this might be done with the widely recognized initialisms US and GNP spaced together, with a link to appropriate articles, if it is not already explained: US GNP, rather than the made-up initialism USGNP.
HTML elements: The software that Wikipedia runs on does not support HTML abbreviation elements (<acronym> or <abbr>); therefore, these tags are not inserted into the source (see Mediazilla:671).

Italics

Emphasis: Italics are used sparingly to emphasize words in sentences (bolding is normally not used at all for this purpose). Generally, the more highlighting in an article, the less the effect of each instance.

Titles

Italics are used for the titles of works of literature and art, such as books, paintings and musical albums. The titles of articles, chapters, songs and other short works are not italicized, but are enclosed in double quotation marks.

Italics are not used for major revered religious works (for example the Bible, the Koran, and the Talmud).

Words as words: Italics are used when mentioning a word or letter (see Use–mention distinction) or a string of words up to a full sentence: "The term panning is derived from panorama, a word coined in 1787"; "The most commonly used letter in English is e". For a whole sentence, quotation marks may be used instead: (1) The preposition in She sat on the chair is on, or (2) The preposition in "She sat on the chair" is on. Mentioning (to discuss such features as grammar, wording and punctuation) is different from quoting (in which something is usually expressed on behalf of a quoted source).

Foreign words: Wikipedia prefers italics for phrases in other languages and for isolated foreign words that do not yet have everyday use in non-specialized English.
Quotations in italics: For quotations, use only quotation marks (for short quotations) or block quoting (for long ones), not italics. (See Quotations below.) This means that (1) a quotation is not italicized inside quotation marks or a block quote just because it is a quotation, and (2) italicization is not used as a substitute for proper quotation formatting.
Italics within quotations: Italics are used within quotations if they are already in the source material, or are added by Wikipedia to give emphasis to some words. If the latter, an editorial note "[emphasis added]" should appear at the end of the quotation ("Now cracks a noble heart. Good night sweet prince: And flights of angels sing thee to thy rest" [emphasis added]).; If the source uses italics for emphasis, and it is desirable to stress that Wikipedia has not added the italics, the editorial note "[emphasis in original]" should appear after the quote.
Effect on nearby punctuation: Italicization is restricted to what should properly be affected by italics, and not the punctuation that is part of the surrounding sentence.

Incorrect:	What are we to make of that?
Correct:	What are we to make of that?
		(The question mark applies to the whole sentence, not just to the emphasized that.)
Correct:	Four of Patrick White's most famous novels are A Fringe of Leaves, The Aunt's Story, Voss and The Tree of Man.
		(The commas, period, and and are not italicized.)

Italicized links: The italics markup must be outside the link markup, or the link will not work; however, internal italicization can be used in piped links.

Incorrect:	The opera [[''Turandot'']] is his best.
Correct:	The opera ''[[Turandot]]'' is his best.
Correct:	The [[USS Adder (SS-3)\|USS ''Adder'' (SS-3)]] was a submarine.

Non-breaking spaces

A non-breaking space (also known as a hard space) is recommended to prevent the end-of-line displacement of elements that could be awkward at the beginning of a new line:
- in compound expressions in which figures and abbreviations or symbols are separated by a space (17 kg, AD 565, 2:50 pm), including scientific names of species where the genus is abbreviated (C. elegans);
- on the left side of spaced en dashes; and
- in other places where displacement might be disruptive to the reader, such as £11 billion, 5° 24′ 21.12″ N, Boeing 747, and the first two items in 7 World Trade Center.
A hard space can be produced with the HTML code   instead of the space bar, or by pressing the key combination option–space bar on a Mac: 19 kg yields a non-breaking 19 kg.
Hard spaces can also be produced by using the {{nowrap}} template: {{nowrap|8 sq ft}} produces a non-breaking 8 sq ft. This is especially useful for short constructions requiring two or more hard spaces, as in the preceding example. Template {{nowrap}} has the disadvantage that if the enclosed text starts or ends with a space, these spaces are forced outside in the resulting HTML, and unpredicted breaks may occur. If   occurs right before {{nowrap}}, or at the start of text within {{nowrap}}, some browsers allow a break at that point.
Unlike normal spaces, multiple hard spaces are not compressed by browsers into a single space.

Quotations

တူဝ်ယေႃႈ: WP:MOSQUOTE

Minimal change: Wherever reasonable, preserve the original style, spelling and punctuation. Where there is a good reason not to do so, insert an editorial explanation of the changes, usually within square brackets (e.g., [for example]).
Attribution: The author of a quote of a full sentence or more should be named; this is done in the main text and not in a footnote. However attribution is unnecessary for quotations from the subject of the article or section. When preceding a quotation with its attribution, avoid characterizing it in a biased manner.
Quotations within quotations: When a quotation includes another quotation (and so on), start with double-quotes outermost and working inward, alternate single-quotes with double-quotes. For example, the following three-level quotation: "She disputed his statement that 'Voltaire never said "I disapprove of what you say, but I will defend to the death your right to say it." ' " Adjacent quote marks, as at the end of this example, are separated by a non-breaking space ( ), though this may not work on some older browsers.
Linking: Unless there is a good reason to do so, Wikipedia avoids linking from within quotes, which may clutter the quotation, violate the principle of leaving quotations unchanged, and mislead or confuse the reader.
Block quotations: A long quote (more than four lines, or consisting of more than one paragraph, regardless of number of lines) is formatted as a block quotation, which Wikimedia's software will indent from both margins. Block quotes are not enclosed in quotation marks (especially including decorative ones such as those provided by the {{cquote}} template, used only for pull quotes). Block quotes can be enclosed between a pair of <blockquote>...</blockquote> HTML tags, or {{quotation}} or {{quote}} can be used. Note: The current version of Wikipedia's MediaWiki software will not render multiple paragraphs inside a <blockquote> simply by spacing the paragraphs apart with blank lines. A workaround is to enclose each of the block-quoted paragraphs in its own ... element.

Example:

<blockquote> And bring us a lot of horilka, but not of that fancy kind with raisins, or with any other such things—bring us horilka of the purest kind, give us that demon drink that makes us merry, playful and wild! —[[Nikolai Gogol]], ''[[Taras Bulba]]'' </blockquote>

The result appears indented on both sides (and, depending on browser software, may also be in a smaller font):

And bring us a lot of horilka, but not of that fancy kind with raisins, or with any other such things—bring us horilka of the purest kind, give us that demon drink that makes us merry, playful and wild!

—Nikolai Gogol, Taras Bulba

The {{quote}} template provides the same semantic HTML formatting, as well as a workaround for the paragraph spacing bug and a pre-formatted attribution line:

{{quote|And bring us a lot of horilka, but not of that fancy kind with raisins, or with any other such things—bring us horilka of the purest kind, give us that demon drink that makes us merry, playful and wild!|[[Nikolai Gogol]]|''[[Taras Bulba]]''}}

Which results in:

And bring us a lot of horilka, but not of that fancy kind with raisins, or with any other such things—bring us horilka of the purest kind, give us that demon drink that makes us merry, playful and wild!
—Nikolai Gogol, Taras Bulba

Punctuation

တူဝ်ယေႃႈ: WP:PUNC WP:PUNCT

Quotation marks

The term quotation(s) in the material below also includes other uses of quotation marks such as those for titles of songs, chapters, and episodes; unattributable aphorisms; literal strings; "scare-quoted" passages and constructed examples.

Double or single: Quotations are enclosed within "double quotes". Quotations within quotations are enclosed within 'single quotes'.
Inside or outside: Punctuation marks are placed inside the quotation marks only if the sense of the punctuation is part of the quotation. This system is referred to as logical quotation; it is used by Wikipedia both because of the principle of minimal change, and also because the method is less prone to misquotation, ambiguity and the introduction of errors in subsequent editing.

Correct:	Arthur said, "The situation is deplorable and unacceptable."
	(The period is part of the quoted text.)
Correct:	Arthur said that the situation was "deplorable".
	(The period is not part of the quoted text.)
Correct:	Martha asked, "Are you coming?"
	(The question mark belongs inside because the quoted text itself was a question.)
Correct:	Did Martha say, "Come with me"?
	(The very quote is being questioned, so the question mark belongs outside; any punctuation at the end of the original quote is omitted.)

When quoting a sentence fragment which ends in a period, some judgement is required: if the fragment communicates a complete sentence, the period can be placed inside. The period should be omitted if the quotation is in the middle of a sentence.

Correct:

Martha said, "Come with me", and they did.

Article openings: When the title of an article appearing in the lead paragraph requires quotation marks (for example, the title of a song or poem), the quotation marks should not be in boldface, as they are not part of the title:

Correct:

"Jabberwocky" is a nonsense poem by Lewis Carroll.

Block quotes: As already noted above, we use quotation marks or block quotes (not both) to distinguish long quotations from other text. Multiparagraph quotations are always block-quoted. The quotations must be precise and exactly as in the source. The source should be cited clearly and precisely to enable readers to find the text that supports the article content in question.

Straight or curly?

There are two options when considering the look of the quotation marks (that is, the glyph):

Typewriter or straight style: "text", 'text', text's
Typographic or curly style: “text”, ‘text’, text’s

(Emphasis added to better distinguish between the glyphs.)

Grave and acute accents or backticks (`text´) are neither quotation marks nor apostrophes, and must not be used in their place.
Foreign characters that resemble apostrophes, such as transliterated Arabic ayin (ʿ) and alif (ʾ), are represented by their correct Unicode characters, despite possible display problems. If this is not feasible, use a straight apostrophe instead.

The exclusive use of straight quotes and apostrophes is recommended. They are easier to type in reliably, and to edit. Mixed use interferes with searching (a search for Korsakoff's syndrome could fail to find Korsakoff’s syndrome and vice versa).

Whenever quotation marks or apostrophes appear in article titles, make a redirect from the same title but using the alternative glyphs.

Other matters

A quotation is not italicized simply because it is a quotation.
If an entire sentence is quoted in such a way that it becomes a grammatical part of the larger sentence, the first letter loses its capitalization: It turned out to be true that "a penny saved is a penny earned".
If a word or phrase appears in an article in single quotes, such as 'abcd', Wikipedia's search facility will find that word or phrase only if the search string is also within single quotes. This difficulty does not arise for double quotes, and this is one of the reasons the latter are recommended.

Brackets and parentheses

If a sentence contains a bracketed phrase, the sentence punctuation comes outside the brackets (as shown here). However, where one or more sentences are wholly inside brackets, their punctuation comes inside the brackets (see further details below). These rules apply to both round "( )" brackets, often called parentheses, and square "[ ]" brackets. There should not be a space next to a bracket on its inner side. An opening bracket should be preceded by a space, except in unusual cases; for example, when it is preceded by:

An opening quotation mark

He rose to address the meeting: "(Ahem) ... Ladies and gentlemen, welcome!"

Another opening bracket

Only the royal characters in the play ([Prince] Hamlet and his family) habitually speak in blank verse.

A portion of a word

We journeyed on the Inter[continental].

There should be a space after a closing bracket, except where another punctuation mark (other than an apostrophe or a dash) follows, and in unusual cases similar to those listed for opening brackets.

If sets of brackets must be nested, use the contrasting type (normally, square brackets appear within round brackets [like this]). Often, it is better to revise the sentence to reduce clutter, using commas, semicolons, colons or dashes instead.

Avoid adjacent sets of brackets—either put the parenthetic phrases in one set separated by commas, or rewrite the sentence. For example:

Incorrect:	Nikifor Grigoriev (c. 1885–1919) (also known as Matviy Hryhoriyiv) was a Ukrainian insurgent leader.
Correct:	Nikifor Grigoriev (c. 1885–1919), also known as Matviy Hryhoriyiv, was a Ukrainian insurgent leader.
Correct:	Nikifor Grigoriev (c. 1885–1919) was a Ukrainian insurgent leader. He was also known as Matviy Hryhoriyiv.

Square brackets are used to indicate editorial replacements and insertions of text. They serve three main purposes:

To clarify. ("She attended [secondary] school"—where this was the intended meaning, but the type of school was unstated in the original sentence.)
To reduce the size of a quotation. If a source says "X contains Y, and under certain circumstances, X may contain Z as well", it is acceptable to reduce this to "X contains Y [and sometimes] Z", without ellipsis. When an ellipsis (...; see below) is used to indicate material removed from a direct quotation, it should not normally be bracketed.
To make the grammar work: She said that "[she] would not allow this"—where her original statement was "I would not allow this." (Generally, though, it is better to begin the quotation after the problematic word: She said that she "would not allow this.")

The use of square-bracketed wording should never alter the intended meaning of a quotation.

Sentences and brackets

If any sentence includes material that is enclosed in square or round brackets, it still must end—with a period, or a question or exclamation mark—after those brackets (a rule that applies in all English, whether British or U.S.). The preceding sentence is an example. This principle applies no matter what punctuation is used within the brackets.

Normally, if the words of a sentence begin within brackets, the sentence must also end within those brackets. (This sentence is an example.) There is an exception for matter that is added or modified editorially at the beginning of a sentence for clarity, usually in square brackets: "[Principal Skinner] already told me that," he objected.

A sentence that occurs within brackets in the course of another sentence does not have its first word capitalized just because it starts a sentence. The enclosed sentence may have a question mark or exclamation mark added, but not a period: "Alexander then conquered (who would have believed it?) most of the known world"; "Clare demanded that he drive (she knew he hated driving) to the supermarket." These constructions are usually best avoided, for readability.

Ellipses

တူဝ်ယေႃႈ: WP:ELLIPSES WP:ELLIPSIS

An ellipsis (plural ellipses) is an omission of material from quoted text or some other omission, perhaps of the end of a sentence, often used in the representation of conversation in print. The ellipsis is represented by ellipsis points, a series of three dots (or sometimes four at the end of a sentence).

Style

Ellipses have traditionally been implemented in three ways:

Three unspaced periods (...). This is the easiest way, and gives a predictable appearance in HTML. Recommended.
Pre-composed ellipsis character (…); generated with the … character entity, or by insertion from the set below the edit window. This is harder to input and edit, and too small in some fonts. Not recommended.
Three spaced periods (. . .). This is an older style that is unnecessarily wide and requires non-breaking spaces to keep it from breaking at the end of a line. Strongly deprecated.

Function

Use an ellipsis if material is omitted in the course of a quotation, unless square brackets are used to gloss the quotation (see above, and the next point below). Put a space on each side of an ellipsis, except at the very start or end of a quotation. Sentence-final punctuation after an ellipsis is shown only if it is textually important (as is often the case with exclamation points and question marks, and rarely with periods); no space comes between the ellipsis and the terminal punctuation. Use non-breaking spaces ( ) only as needed to prevent improper line breaks, e.g.:

To keep a quotation mark from being separated from the start of the quotation: "... we are still worried."
To keep the ellipsis from wrapping to the next line: "France, Germany, ... and Belgium but not the USSR."

Pause or suspension of speech: Three periods are occasionally used to represent a pause in or suspense of speech, in which case the punctuation is retained in its original form (Virginia's startled reply was: "Could he...? No, I cannot believe it!"). This usage is avoided in Wikipedia except in direct quotations.

With square brackets: An ellipsis does not normally need square brackets around it, since its function is usually obvious—especially if the guidelines above are followed. But square brackets may optionally be used for precision, to make it clear that the ellipsis is not itself quoted; this is usually only necessary if the quoted passage also uses three periods in it to indicate a pause or suspension. The ellipsis should follow exactly the principles given above, but with square brackets inserted immediately before and after it. (Her long rant continued: "How do I feel? How do you think I... look, this has gone far enough! [...] I want to go home!")

Serial commas

တူဝ်ယေႃႈ: WP:COMMA

A serial comma (also known as the Oxford comma or Harvard comma) is a comma used immediately before a conjunction in a list of three or more items: the phrase ham, chips, and eggs contains a serial comma, while the variant ham, chips and eggs omits it. Both styles are acceptable in Wikipedia, but in a case where including or omitting the comma clarifies the meaning of the sentence, that solution should be adopted.

Sometimes omitting the comma can lead to an ambiguous sentence, as in this example: The author would like to thank her parents, Sinéad O'Connor and President Bush, which may be a list of either four or two people.

Including the comma can also cause ambiguity, as in: The author would like to thank her mother, Sinéad O'Connor, and President Bush, which may be a list of either two or three people.

In such cases of ambiguity there are three ways to clarify:

Use or omit the serial comma to avoid ambiguity.
Recast the sentence.
Format the list, e.g. with paragraph breaks and numbered paragraphs.

Colons

A colon (:) informs the reader that what comes after it proves, explains, or modifies what has come before, or is a list alluded to before. More specifically, the colon is an introduction that warns the reader to be prepared for a closely related construction that is about to follow: this following segment may be the elements of a set illustrating the statement, or the logical consequence or effect of a fact stated before, or another closely related modifying sentence, or a direct speech in combination with quotation marks.

Colons should not have spaces before them:

Correct:	He attempted it in two years: 1941 and 1943
Incorrect:	He attempted it in two years : 1941 and 1943

Colons should have complete sentences before them:

Correct:	He attempted it in two years: 1941 and 1943
Incorrect:	The years he attempted it included: 1941 and 1943

Hyphens

တူဝ်ယေႃႈ: WP:HYPHEN

Hyphens (-) indicate conjunction. There are three main uses.

To distinguish between homographs (re-dress = dress again, but redress = remedy or set right).
To link certain prefixes with their main word (non-linear, sub-section, super-achiever):
There is a clear trend, not yet complete, to join both elements in all varieties of English (subsection, nonlinear), particularly in North America. British English tends to hyphenate when the letters brought into contact are the same (non-negotiable, sub-basement) or are vowels (pre-industrial), or where a word is uncommon (co-proposed, re-target) or may be misread (sub-era, not subera). North American English reflects the same factors, but tends strongly to close up without a hyphen when possible. Consult a good dictionary, and see WP:ENGVAR.
To link related terms in compound adjectives and adverbs:
- A hyphen can help with ease of reading (face-to-face discussion, hard-boiled egg); a hyphen is particularly useful in long nominal groups where non-experts are part of the readership, such as in Wikipedia's scientific articles: gas-phase reaction dynamics.
- A hyphen can help to disambiguate (little-used car, not a reference to the size of a used car).
- Many compound adjectives that are hyphenated when used attributively (before the noun they qualify—a light-blue handbag), are not hyphenated when used predicatively (after the noun—the handbag was light blue). Where there would be a loss of clarity, the hyphen may be used in the predicative case too (hand-fed turkeys, the turkeys were hand-fed).
- A hyphen is not used after an -ly adverb (wholly owned subsidiary) unless part of a larger compound (a slowly-but-surely strategy).
- A hyphen is normally used when the adverb well precedes a participle used attributively (a well-meaning gesture; but normally a very well managed firm, since well itself is modified); and even predicatively, if well is necessary to, or alters, the sense of the adjective rather than simply intensifying it (the gesture was well-meaning, the child was well-behaved, but the floor was well polished).
- A hanging hyphen is used when two compound adjectives are separated (two- and three-digit numbers, a ten-car or -truck convoy).
- Values and units used as compound adjectives are hyphenated only where the unit is given as a whole word. Where hyphens are not used, values and units are always separated by a non-breaking space ( ).

Incorrect:	9-mm gap
Correct:	9 mm gap (entered as 9 mm gap)
Incorrect:	9 millimetre gap
Correct:	9-millimetre gap
Correct:	12-hour shift
Correct:	12 h shift

A hyphen is never followed or preceded by a space, except when hanging (see above) or when used to display parts of words independently, such as the prefix sub- and the suffix -less.

A hyphen is used only to mark conjunction—not to mark disjunction (for which en dashes are correct: see below).

Hyphenation involves many subtleties that cannot be covered here; the rules and examples presented above illustrate the broad principles that inform current usage.

Do not use hyphens (-) to write minus signs (−), except in code.

Dashes

တူဝ်ယေႃႈ: WP:DASH WP:MOSDASH

Two kinds of dash are used on Wikipedia. The article on dashes shows common input methods for both kinds.

En dashes

En dashes (–) have three distinct roles.

To indicate disjunction. In this role there are two main applications.
- To convey the sense of to or through, particularly in ranges (pp. 211–19, 64–75%, the 1939–45 war, May–November) and where movement is involved (Dublin–Belfast route). The word to, rather than an en dash, is used when a number range involves a negative value or might be misconstrued as a subtraction (−3 to 1, not −3–1). This is also the case when the nearby wording demands it, e.g., he served from 1939 to 1941 and not he served from 1939–1941, in which from and to are complementary and should both be spelled out.
- As a substitute for some uses of and, to or versus for marking a relationship involving independent elements in certain compound expressions (Canada–US border, blood–brain barrier, time–altitude graph, 4–3 win in the opening game, male–female ratio, 3–2 majority verdict, Lincoln–Douglas debate, Michelson–Morley experiment, diode–transistor logic; but a hyphen is used in Sino-Japanese trade, in which Sino-, being a prefix, lacks lexical independence.
  - Spacing: All disjunctive en dashes are unspaced, except when there is a space within either or both of the items (the New York – Sydney flight; the New Zealand – South Africa grand final; July 3, 1888 – August 18, 1940, but July–August 1940).
In lists, to separate distinct information within points—particularly track titles and durations, and musicians and their instruments, in articles on music albums. In this role, en dashes are always spaced.
As a stylistic alternative to em dashes (see below).

En dashes in page names

When naming an article, a hyphen is not used as a substitute for an en dash that properly belongs in the title, for example in Eye–hand span. However, editors should provide a redirect page to such an article, using a hyphen in place of the en dash (e.g., Eye-hand span), to allow the name to be typed easily when searching Wikipedia. See also Wikipedia:Naming conventions (precision). The associated talk page name should match the page name exactly.

Minus signs

Do not use an en dash for negative signs and subtraction operators: use the correct unicode character for the minus sign (−) (see also Wikipedia:Manual of Style (mathematics).) Negative signs (−8 °C) are unspaced; subtraction signs (42 − 4 = 38) are spaced.

Em dashes

Em dashes (—) indicate interruption. They are used in two roles.

Parenthesis (Wikipedia—one of the most popular web sites—has the information you need). Here, a pair of em dashes is a more arresting way of interpolating a phrase or clause than a pair of commas, and is less of an interruption than brackets. A pair of em dashes is particularly useful where there are already many commas; em dashes can make such a sentence easier to read, and sometimes they can remove ambiguity.
A sharp break in the flow of a sentence—sharper than is provided by a colon or a semicolon.

Em dashes should not be spaced.

Because em dashes are visually striking, it is preferable to avoid using more than two in a single paragraph. The roles of more than two em dashes in a single sentence can be unclear.

Do not use an em dash for a minus sign.

Spaced en dashes as an alternative to em dashes

Spaced en dashes – such as here – can be used instead of unspaced em dashes in all of the ways discussed above. Spaced en dashes are used by several major publishers, to the complete exclusion of em dashes. One style should be used consistently in an article.

Other dashes

These are avoided on Wikipedia, notably the double-hyphen (--).

Spaces after the end of a sentence

There are no guidelines on whether to use one space or two (French spacing) after the end of a sentence, but the issue is not important, because the difference is visible only in edit boxes; i.e. it is ignored by browsers when displaying the article.

Slashes

Avoid joining two words by a slash (/, also known as a forward slash), as it suggests that the two are related, but does not specify how. It is often also unclear how the construct would be read aloud. Consider replacing a slash with an explanation, or adding one in a footnote. Where possible, reword more fully to avoid uncertainties.

An example: The parent/instructor must be present at all times. Must both be present? (Then write the parent and the instructor.) Must at least one be present? (Then write the parent or the instructor.) Are they the same person? (Use a hyphen: the parent-instructor.)

In circumstances involving a distinction or disjunction, the en dash is usually preferable to the slash, e.g., the novel–novella distinction.

An unspaced slash may be used:

to show pronunciations ("ribald is pronounced /ˈrıb·əld/")
to separate the numerator and denominator in a fraction (7/8 or 7⁄8)
to indicate regular defined yearly periods that do not coincide with calendar years (see Wikipedia:Manual of Style (dates and numbers)#Longer periods)
where slashes are used in a phrase outside of Wikipedia, and using a different construction would be inaccurate, unfamiliar or ambiguous

A spaced slash may be used:

to separate run-in lines of poetry or song (To be or not to be: that is the question: / Whether 'tis nobler in the mind to suffer / The slings and arrows of outrageous fortune)
to separate any construction that can be separated with an unspaced slash when readability would be enhanced by doing so, most often when the items being separated are complex, such as involving a number of abbreviations, numbers; compare the NY 31 east / NY 370 exit with the NY 31 east/NY 370 exit.

Spaced slashes should be coded with a leading non-breaking space and a trailing normal space, e.g., x / y (which renders as x / y), to prevent line breaks introducing readability problems.

The backslash character, \, is never used in place of a slash.

In general prose, prefer ÷ to / when representing mathematical division. (See Wikipedia:Manual of Style (dates and numbers)#Common mathematical symbols and Help:Displaying a formula for more information.)

And/or

The term and/or is usually awkward. In general, where it is important to mark an inclusive or, use x or y, or both, rather than x and/or y. For an exclusive or, use either x or y, and optionally add but not both, if it is necessary to stress the exclusivity.

Where more than two possibilities are presented, from which a combination is to be selected, it is even less desirable to use and/or. With two possibilities, at least the intention is clear; but with more than two it may not be. Instead of x, y, and/or z, use an appropriate alternative, such as one or more of x, y, and z; some or all of x, y, and z.

Sometimes or is ambiguous in another way: "Wild dogs, or dingoes, inhabit this stretch of land". Are wild dogs and dingoes the same or different? For one case write: "wild dogs (dingoes) inhabit ..." (dingoes are wild dogs); for the other case write: "either wild dogs or dingoes inhabit ..." (I don't know which).

Question marks and exclamation marks

Question and exclamation marks are never preceded by a space in normal prose.
The exclamation mark is used with restraint: it is an expression of surprise or emotion that is generally unsuited to a scholarly or encyclopedic register.
Clusters of question marks, exclamation marks, or a combination of them (such as the interrobang) are highly informal and inappropriate in Wikipedia articles.
For the use of these marks in association with quotation marks, see #Quotations above.

Punctuation and inline citations

The placement of inline citations relative to sentence punctuation is dealt with separately, within the Wikipedia guidelines concerning References.

Chronological items

Precise language

Avoid statements that will date quickly, except on pages that are regularly refactored, such as those that cover current events. Avoid such items as recently and soon (unless their meaning is clear in a storyline), currently (except on rare occasions when it is not redundant), in modern times, is now considered and is soon to be superseded. Instead, use either:

more precise items (since the start of 2005; during the 1990s; is expected to be superseded by 2008); or
an as of phrase (as of August 2007), which is a signal to readers of the time-dependence of the statement, and to later editors of the need to update the statement (see As of).

Times

Context determines whether the 12- or 24-hour clock is used; in both, colons separate hours, minutes and seconds (1:38:09 pm and 13:38:09).

12-hour clock times end with dotted or undotted lower-case a.m. or p.m., or am or pm, which are spaced (2:30 p.m. or 2:30 pm, not 2:30p.m. or 2:30pm). Noon and midnight are used rather than 12 pm and 12 am; whether midnight refers to the start or the end of a date will need to be specified unless this is clear from the context.
24-hour clock times have no a.m., p.m., noon or midnight suffix. Discretion may be used as to whether the hour has a leading zero (08:15 or 8:15). 00:00 refers to midnight at the start of a date, 12:00 to noon, and 24:00 to midnight at the end of a date.

Dates

Wikipedia does not use ordinal suffixes or articles, or put a comma between month and year.

Incorrect:	February 14th, 14th February, the 14th of February
Correct:	14 February, February 14
Incorrect:	October, 1976
Correct:	October 1976

Date ranges are preferably given with minimal repetition (5–7 January 1979; September 21–29, 2002), using an unspaced en dash. If the autoformatting function is used, the opening and closing dates of the range must be given in full (see Autoformatting and linking) and be separated by a spaced en dash.
Rarely, a night may be expressed in terms of the two contiguous dates using a slash (the bombing raids of the night of 30/31 May 1942); this cannot be done using the autoformatting function.
Yearless dates (5 March, March 5) are inappropriate unless the year is obvious from the context. There is no such ambiguity with recurring events, such as "January 1 is New Year's Day".
ISO 8601 dates (1976-05-13) are uncommon in English prose and are generally not used in Wikipedia. However, they may be useful in long lists and tables for conciseness and ease of comparison.

Longer periods

Months are expressed as whole words (February, not 2), except in the ISO 8601 format. Abbreviations such as Feb are used only where space is extremely limited, such as in tables and infoboxes. Do not insert of between a month and a year (April 2000, not April of 2000).

တူဝ်ယေႃႈ: WP:SEASON

Seasons. Because the seasons are not simply reversed in each hemisphere—and areas near the equator tend to have just wet and dry seasons—neutral wording may be preferable (in early 1990, in the second quarter of 2003, around September). Use a date or month rather than a season name, unless there is a logical connection (the autumn harvest). Seasons are normally spelled with a lower-case initial.
Years
- Years are normally expressed in digits; a comma is not used in four-digit years (1988, not 1,988).
- Avoid inserting the words the year before the digits (1995, not the year 1995), unless the meaning would otherwise be unclear.
  - Either CE and BCE or AD and BC can be used—spaced, undotted (without periods) and upper-case. Choose either the BC-AD or the BCE-CE system, but not both in the same article. AD appears before or after a year (AD 1066, 1066 AD); the other abbreviations appear after (1066 CE, 3700 BCE, 3700 BC). The absence of such an abbreviation indicates the default, CE-AD. It is inappropriate for a Wikipedia editor to change from one style to another unless there is some substantial reason for the change; the Manual of Style favors neither system over the other.
  - Uncalibrated (bce) radiocarbon dates: Do not give uncalibrated radiocarbon dates (represented by the lower-case bce unit, occasionally bc or b.c. in some sources), except in directly quoted material, and even then include a footnote, a [square-bracketed editor's note], or other indication to the reader what the calibrated date is, or at least that the date is uncalibrated. Calibrated and uncalibrated dates can diverge surprisingly widely, and the average reader does not recognize the distinction between bce and BCE-BC.
  - Year ranges, like all ranges, are separated by an en dash (do not use a hyphen or slash (2005–08, not 2005-08 or 2005/08). A closing CE-AD year is normally written with two digits (1881–86) unless it is in a different century from that of the opening year (1881–1986). The full closing year is acceptable, but abbreviating it to a single digit (1881–6) or three digits (1881–886) is not. A closing BCE-BC year is given in full (2590–2550 BCE). While one era signifier at the end of a date range still requires an unspaced en dash (12–5 BC), a spaced en dash is required when a signifier is used after the opening and closing years (5 BC – 29 AD).
  - A slash may be used to indicate regular defined yearly periods that do not coincide with calendar years (the financial year 1993/4).
  - Abbreviations indicating long periods of time ago—such as BP (before present), as well as various annum-based units such as Ka (kiloannum) and kya (thousand years ago), Ma (megaannum) and mya (million years ago), and Ga (gigaannum or billion years ago)—are given as full words and wikilinked on first occurrence.
  - To indicate around, approximately, or about, the abbreviations c. and ca. are preferred over circa, approximately or approx., and are spaced (c. 1291). Use a question mark instead (1291?) only if the date is in fact questioned rather than approximate. (The question mark may mistakenly be understood as a sign that editors have simply not checked the date.)
Decades contain no apostrophe (the 1980s, not the 1980's); the two-digit form is used only where the century is clear (the '80s or the 80s).

Numbers

Numbers as figures or words

Several detailed recommendations for when to use figures and when to spell out numbers are at Wikipedia:Manual of Style (dates and numbers)#Numbers as figures or words.

Large numbers

Commas are used to break the sequence every three places (2,900,000).
Large rounded numbers are generally assumed to be approximations; only where the approximation could be misleading is it necessary to qualify with about or a similar term.
Avoid over-precise values where they are unlikely to be stable or accurate, or where the precision is unnecessary in the context. (The speed of light in a vacuum is 299,792,458 metres per second is probably appropriate, but The distance from the Earth to the Sun is 149,014,769 kilometres and The population of Cape Town is 2,968,790 would usually not be, because both values are unstable at that level of precision, and readers are unlikely to care in the context.)
Scientific notation (6.02 × 10²³) is preferred in scientific contexts.
Where values in the millions occur a number of times through an article, upper-case M may be used for million, unspaced, after using the full word at the first occurrence. (She bequeathed her fortune of £100 million unequally: her eldest daughter received £70M, her husband £18M, and her three sons just £4M each.)
Billion is understood as 10⁹. After the first occurrence in an article, billion may be abbreviated to unspaced bn ($35bn).

Decimal points

A decimal point is used between the integral and the fractional parts of a decimal; a comma is never used in this role (6.57, not 6,57).
The number of decimal places should be consistent within a list or context (The response rates were 41.0 and 47.4 percent, respectively, not The response rates were 41 and 47.4 percent, respectively), except in the unusual instances where the items were measured with unequal precision.
Numbers between minus one and plus one require a leading zero (0.02, not .02); exceptions are performance averages in sports where a leading zero is not commonly used, and commonly used terms such as .22 caliber.

Percentages

Percent or per cent are commonly used to indicate percentages in the body of an article. The symbol % may be more common in scientific or technical articles, or in complex listings.
The symbol is unspaced (71%, not 71 %).
In tables and infoboxes, the symbol is used, not the words percent or per cent.
Ranges are preferably formatted with one rather than two percentage signifiers (22–28%, not 22%–28%).

Units of measurement

တူဝ်ယေႃႈ: WP:UNITS

Which system to use

For US-related articles, the main units are US units; for example, 23 miles (37 km).
For UK-related, the main units are either metric or imperial (consistently within an article).
For other country-related articles, the main units are metric; for example, 37 kilometres (23 mi).
American English uses -er endings for metric units (liter, kilometer); all other varieties of English, including Canadian, use -re (litre, kilometre).
In scientific articles, use the units employed in the current scientific literature on that topic. This will usually be SI, but not always; for example, natural units are often used in relativistic and quantum physics, and Hubble's constant should be quoted in its most common unit of (km/s)/Mpc rather than its SI unit of s⁻¹.
If editors cannot agree on the sequence of units, put the source value first and the converted value second. If the choice of units is arbitrary, use SI units as the main unit, with converted units in parentheses.

Conversions

Conversions to and from metric and imperial/US units should generally be provided. There are two exceptions:
- articles on scientific topics where there is consensus among the contributors not to convert the metric units, in which case the first occurrence of each unit should be linked;
- where inserting a conversion would make a common expression awkward (The four-minute mile).
In the main text, give the main units as words and use unit symbols or abbreviations for conversions in parentheses; for example, a pipe 100 millimetres (4 in) in diameter and 16 kilometres (10 mi) long or a pipe 4 inches (100 mm) in diameter and 10 miles (16 km) long. The exception is that where there is consensus to do so, the main units may also be abbreviated in the main text after the first occurrence.
Converted values should use a level of precision similar to that of the source value; for example, the Moon is 380,000 kilometres (240,000 mi) from Earth, not (236,121 mi). The exception is small numbers, which may need to be converted to a greater level of precision where rounding would be a significant distortion; for example, one mile (1.6 km), not one mile (2 km).
Category:Conversion templates can be used to convert and format many common units, including {{convert}}, which includes non-breaking spaces.
In a direct quotation:
- conversions required for units cited within direct quotations should appear within square brackets in the quote;
- if the text contains an obscure use of units (e.g., five million board feet of lumber), annotate it with a footnote that provides standard modern units, rather than changing the text of the quotation.
Measurements should be accompanied by a proper citation of the source using a method described at the style guide for citation.
Where footnoting or citing sources for values and units, identify both the source and the original units.

SI symbols and unit abbreviations

Non-breaking spaces are used between values and units; see the Non-breaking spaces section above.
Standard abbreviations and symbols for units are undotted (do not carry periods). For example, m for metre and kg for kilogram (not m. or kg.), in for inch (not in., or ″), ft for foot (not ft., or ′) and lb for pound (not lb. or #).
The degree symbol is °. Using any other symbol (e.g., masculine ordinal º or "ring above" ˚) for this purpose is incorrect.
Do not append an s for the plurals of unit symbols (kg, km, in, lb, not kgs, kms, ins, lbs). A lowercase 's' is the SI symbol for second; thus, 'kgs' can be confused with 'kg s', which means "kilogram-second".
Temperatures are always accompanied by °C for degrees Celsius, °F for degrees Fahrenheit, or K for kelvin (35 °C, 62 °F, and 5,000 K, not 5,000 °K).
Values and unit symbols are spaced (25 kg, not 25kg). The exceptions are degrees, minutes and seconds for angles and coordinates (the coordinate is 5° 24′ 21.12″ N, the pathways meet at a 90° angle, but the average temperature is 18 °C).
Squared and cubic metric-symbols are always expressed with a superscript exponent (5 km², 2 cm³); squared imperial and US unit abbreviations may be rendered with sq, and cubic with cu (15 sq mi, 3 cu ft)

Do not use the unicode characters ² and ³, but rather write 2 and 3 to produce the superscripts ² and ³. The superscripted 2 and 3 are easier to read, especially on small displays, and ensures that exponents are properly aligned (compare x¹x²x³x⁴ vs x¹x²x³x⁴).

In tables and infoboxes, use symbols and abbreviations for units, not words.
Some different units share the same name. These examples show the need to be specific.
- Use US or imperial gallon rather than just gallon.
- Use nautical or statute mile rather than mile in nautical and aeronautical contexts.
- Use long ton or short ton rather than just ton (the metric unit—the tonne—is also known as the metric ton).
Ranges are preferably formatted with one rather than two unit signifiers (5.9–6.3 kg, not 5.9 kg – 6.3 kg).

Unnecessary vagueness

Use accurate measurements whenever possible.

Vague	Precise
The wallaby is small.	The average male wallaby is 1.6 metres (63 in) from head to tail.
Prochlorococcus marinus is a tiny cyanobacterium.	The cyanobacterium Prochlorococcus marinus is 0.5 to 0.8 micrometres across.
The large oil spill stretched a long way down the Alaskan coast.	The oil spill that drifted down the Alaskan coast was 3 statute miles (5 km) long and 1,000 feet (300 m) wide.

Currencies

တူဝ်ယေႃႈ: WP:$

Which currency to use

In country-specific articles, such as Economy of Australia, use the currency of the country.
In non-country-specific articles such as Wealth, use US dollars (US$123).

Formatting

Fully identify a currency on its first appearance (AU$52); subsequent occurrences are normally given without the country identification (just $88), unless this would be unclear. The exception to this is in articles related to the US and the UK, in which the first occurrence may also be shortened ($34 and £22, respectively), unless this would be unclear.
Do not place a currency symbol after the value (123$, 123£, 123€), unless the symbol is normally written as such. Do not write $US123 or $123 (US).
Currency abbreviations that come before the number are unspaced if they end in a symbol (£123, €123), and spaced if they end in an alphabetical character (R 75). Do not place EU or a similar prefix before the € sign.
If there is no common English abbreviation or symbol, use the ISO 4217 standard.
Ranges are preferably formatted with one rather than two currency signifiers ($250–300, not $250–$300).
Conversions of less familiar currencies may be provided in terms of more familiar currencies, such as the euro or the US dollar. Conversions should be in parentheses after the original currency, with the year given as a rough point of reference; for example, 1,000 Swiss francs (US$763 in 2005), rounding to the nearest whole unit.
Consider linking the first occurrence of a symbol for less well-known currencies (₮146); it is generally unnecessary to link the symbols of well-known currencies.

Common mathematical symbols

For a negative sign or subtraction operator, use a minus sign (−), input by clicking on it in the insert box beneath the edit window or by typing in −), or an en dash (see En dashes); do not use a hyphen, unless writing code.
For a multiplication sign between numbers, use ×, which is input by clicking on it in the edit toolbox under the edit window or by typing × in; do not use an asterisk between numbers in non-technical articles; however, the unspaced letter x is accepted as a substitute for by in such terms as "4x4".
Exponentiation is indicated using a superscript, aⁿ; do not use a caret, a^n. Exponential notation can be spaced or unspaced, depending on circumstances; do not use E notation.
Symbols for binary operators and relations are spaced on both sides, including:
- plus, minus, and plus-or-minus (as operators): + − ±
- multiplication and division: × ÷
- equals, does not equal, equals approximately: = ≠ ≈
- is less than, is less than or equal to, is greater than, is greater than or equal to: < ≤ > ≥

Simple tabulation

Lines that start with blank spaces in the editing window are displayed boxed and in a fixed-width font, for simple tabulation. Lines that contain only a blank space insert a blank line into the table. For a complete guide to constructing tables, see Meta:Help:Table.

Usage

Possessives

For thorough treatment of the English possessive see Apostrophe.

It's is the short form of it is or it has; the possessive its has no apostrophe.
Usage varies for the possessive of singular nouns ending in s sounds. Maintain consistency (James' house or James's house, but not both in the same article). Some forms almost always take an extra s (Ross's father); some usually do not (Socrates' wife; Moses' ascent of Sinai; Jesus' last words).

Avoid first-person pronouns

Wikipedia articles must not be based on one person's opinions or experiences; thus, I is never used, except when it appears in a quotation. For similar reasons, avoid we; a sentence such as We should note that some critics have argued in favor of the proposal sounds more personal than encyclopedic.

Nevertheless, it is sometimes appropriate to use we when referring to an experience that any reader would be expected to have, such as general perceptual experiences. For example, although it might be best to write When most people open their eyes, they see something, it is still legitimate to write When we open our eyes, we see something. It is also acceptable to use we in historical articles to mean the modern world as a whole (The text of De re publica has come down to us with substantial sections missing).

Avoid second-person pronouns

Use of the second person (you), which is often ambiguous and contrary to the tone of an encyclopedia, is discouraged. Instead, refer to the subject of the sentence or use the passive voice—for example:

Use:	When a player moves past "Go", that player collects $200.
Use:	Players passing "Go" collect $200.
Use:	$200 is collected when passing "Go".
Do not use:	When you move past "Go", you collect $200.

This guideline does not apply to quoted text, which should be quoted exactly, nor to the Wikipedia namespace, where you refers to the writers to whom articles in the namespace are addressed.

Avoid contested vocabulary

Words and phrases like thusly, overly, whilst, amongst, as per, refute in the sense of dispute, along with several others, should be avoided because they are not widely accepted—at least in some of their applications. Some are regional, so unsuitable in an international encyclopedia (see National varieties of English below). Some give an impression of "straining for formality", and therefore of an insecure grasp of English. See List of English words with disputed usage, Words to avoid, and List of frequently misused English words; see also Identity and Gender-neutral language below.

Avoid contractions

In general, the use of contractions—such as don't, can't, won't, they'd, should've, it's—is informal and should be avoided; however, contractions should be left unchanged when they occur in a quotation.

Avoid instructional and presumptuous language

It is usually preferable to avoid such phrases as remember that and note that, which address readers directly in an unencyclopedic tone. Similarly, phrases such as of course, naturally, obviously, clearly and actually make presumptions about readers' knowledge, and call into question the reason for including the related information in the first place. See Wikipedia:Words to avoid.

Subset terms

A subset term identifies a set of members of a larger class. Common subset terms are including, among, and et cetera (etc.). Do not use two subset terms ("Among the most well-known members of the fraternity include ...", "The elements in stars include hydrogen, helium and iron, etc."). Do not use including to introduce a complete list, where comprising, consisting of, or composed of would be correct.

Plurals

တူဝ်ယေႃႈ: WP:PLURALS

Use the appropriate plural; allow for cases like oblast, or octopus, when a foreign word has been assimilated into English and normally takes an s or es plural, not its original plural.

A number of words like army, company, crowd, fleet, government, majority, mess, number, pack, and party may refer either to a single entity or the members of the set that compose it. In British English they are normally treated as singular or plural according to context; names of towns and countries take plural verbs when they refer to sports teams but singular verbs when they refer to the actual place (or to the club as a business enterprise): England are playing Germany tonight refers to a football team, but England is the most populous country of the United Kingdom refers to the country.

In North American English, these words (and the United States, for historical reasons) are invariably treated as singular. See WP:ENGVAR.

Foreign terms

ထႅမ်းပလဵတ်ႉ:Seealso

Foreign words should be used sparingly.

No common usage in English: Use italics for phrases in other languages and for isolated foreign words that are not current in English.
Common usage in English: Loanwords and borrowed phrases that have common usage in English—praetor, Gestapo, samurai, vice versa, esprit de corps—do not require italics. A rule of thumb is not to italicize words that appear unitalicized in major English-language dictionaries.
Spelling and transliteration

ထႅမ်းပလဵတ်ႉ:Seealso

Names not originally in a Latin alphabet—such as Greek, Chinese or Russian scripts—must be transliterated into characters generally intelligible to English-speakers. Do not use a systematically transliterated name if there is a common English form of the name, such as Tchaikovsky or Chiang Kai-shek.

The use of diacritics (accent marks) on foreign words is neither encouraged nor discouraged; their usage depends on whether they appear in verifiable reliable sources and on the constraints imposed by specialized Wikipedia guidelines.

Within an article, spell a name that appears in the article title as in that title (covered in naming conventions) rather than an alternative spelling, unless there is a good reason to do so, such as may be given in Naming conventions (use English). Spell the other foreign names, phrases and words as most commonly spelled in the English-language references in an article, unless those spellings are idiosyncratic. If the foreign names, phrases or words do not appear in the article's references, then use the spelling as most commonly used in other verifiable reliable sources (for example other English-language dictionaries and encyclopedias). If the foreign phrase or word appears rarely in English, avoid using it.

Sometimes the usage will be influenced by other guidelines such as national varieties of English, which may lead to different usage in different articles.

Identity

တူဝ်ယေႃႈ:

Disputes over the proper name of a person or group are addressed by policies such as Verifiability, Neutral point of view, and Naming conventions where the name appears in an article name. When there is no dispute, the name most commonly used for a person will be the one that person uses for himself or herself, and the most common terms for a group will be those that the group most commonly uses for itself; Wikipedia should use them too.
A transgender, transsexual or genderqueer person's latest preference of name and pronoun should be adopted when referring to any phase of that person's life, unless this usage is overridden by that person's own expressed preference. Nevertheless, write to avoid confusing or seemingly logically impossible text that could result from pronoun usage (e.g., she fathered her first child).
Use specific terminology. For example, often it is more appropriate for people from Ethiopia (a country in Africa) to be described as Ethiopian, not carelessly (with the risk of stereotyping) as African.
To counter an interpretation that is inappropriately essentialist, terms used to describe people should qualify other nouns (black people, not blacks; gay people, not gays). Some groups, however, prefer the direct noun (many Jews, for example, prefer to use that noun rather than Jewish people).
The term Arab (never to be confused with Muslim or Islamic) refers to people and things of ethnic Arab origin. The term Arabic refers to the Arabic language or writing system, and related concepts (Not all Arab people write or converse in Arabic.)
As always in a direct quotation, use the original text, even if the quoted text is inconsistent with the preceding guidelines.

Gender-neutral language

ထႅမ်းပလဵတ်ႉ:Seealso

Consider using gender-neutral language where this can be done with clarity and precision. This does not apply to direct quotations or the titles of works (The Ascent of Man), or where all referents are of one gender, such as in an all-female school (if any student broke that rule, she was severely punished).

Images

တူဝ်ယေႃႈ:

The following general guidelines should be followed in the absence of a compelling reason to do otherwise.

Images of faces should be placed so that the face or eyes look toward the text, on the grounds that the reader's eyes will tend to follow their direction. Therefore, portraits of a face looking to the reader's right should be left-aligned, looking into the main text.
Start an article with a right-aligned lead image. This image is often resized to about 300px.
Multiple images in the same article can be staggered right-and-left (for example: Timpani).
See Wikipedia:Picture tutorial#Avoiding image "stackups" for how to group images and avoid "stack ups".
Avoid sandwiching text between two images facing each other.
Use {{Commons}} to link to more images on Commons, wherever possible. If there are too many images in a given article, a link to the Commons is a good solution. Use of galleries should be in keeping with Wikipedia's image use policy.
Do not place left-aligned images directly below second-level (===) headings, as this disconnects the heading from the text it precedes. Instead, either right-align the image, remove it, or move it to another relevant location.
Use captions to explain the relevance of the image to the article (see #Captions).
Some users need to configure their systems to display large text; forced large thumbnails can leave little width for text, making reading difficult.

Images should not be reversed simply to resolve a conflict between these guidelines; doing so misinforms the reader for the sake of our layout preferences. If an image is ever reversed or otherwise substantially altered, there should be a clear advantage to the reader in doing so (for example, cropping a work of art to focus on a detail that is the subject of commentary), and the alteration must be noted in the caption.

The current image markup for landscape-format and square images is:

[[Image:picture.jpg|thumb|right|Insert caption here]]

and for portrait-format images:

[[Image:picture.jpg|thumb|upright|right|Insert caption here]]

This will result in default image width of 180px and 140px respectively, which may vary proportionately by user preferences. Image rendering in this markup does not depend on image height.

Image size

တူဝ်ယေႃႈ: WP:FORCED

Specifying the size of a thumbnail image is not necessary. The default size is 180px, although logged-in users can override this in their user preferences (up to a maximum of 300px). If an image displays satisfactorily at the default size, it is recommended that no explicit size be specified. Examples of images which typically need more than the default size include lead images (see above) and detailed maps.

Images as text

Textual information should be entered as text rather than as an image. Such text is not searchable and is slow to download over low-bandwidth connections; the image is unlikely to be read as text by devices for the visually impaired, and will deprive those users of information. Text may be colored and decorated with CSS tags and templates if necessary. Even if the problems can be worked around, as by including a caption or internal information, editors should still consider whether fancy text adds anything to the encyclopedia.

Captions

Usage

Photographs and other graphics should always have captions, unless they are "self-captioning" (such as reproductions of album or book covers) or when they are unambiguous depictions of the subject of the article. For example, in a biography article, a caption is not mandatory for a portrait of the subject pictured alone, but might contain the name of the subject and additional information relevant to the image, such as the year or the subject's age.

Formatting

Captions normally start with a capital letter.
Most captions are not complete sentences, but merely nominal groups (sentence fragments) that should not end with a period. If a complete sentence occurs in a caption, that sentence and any sentence fragments in that caption should end with a period.
Captions should not be italicized, except for words that are conventionally italicized.
Captions should be succinct; more information about the image can be included on its description page, or in the main text.

Bulleted and numbered lists

Do not use lists if a passage reads easily using plain paragraphs.
Use numbers rather than bullets only if:
- there is a need to refer to the elements by number;
- the sequence of the items is critical; or
- the numbering has value of its own, for example in a track listing.
All elements in a list should use the same grammatical form and should be consistently either complete sentences or sentence fragments.
- When the elements are complete sentences, they are formatted using sentence case and a final period.
- When the elements are sentence fragments, they are typically introduced by a lead fragment ending with a colon, are formatted using consistently either sentence or lower case, and finish with a final semicolon or no punctuation, except that the last element typically finishes with a final period.

Links

Wikilinks

ထႅမ်းပလဵတ်ႉ:Seealso

Make links only where they are relevant to the context: It is not useful and can be very distracting to mark all possible words as hyperlinks. Links should add to the user's experience; they should not detract from it by making the article harder to read. A high density of links can draw attention away from the high-value links that you would like your readers to follow up. Redundant links clutter the page and make future maintenance harder. A link is the equivalent of a footnote in a print medium. Imagine if every second word in an encyclopedia article were followed by "(see: ...)". Hence, links should not be so numerous as to make the article harder to read.

Check links: After linking, ensure that the destination is the intended one; many dictionary words lead to disambiguation pages and not to complete articles on a concept. An anchor into a targeted page—the label after a pound/hash sign (#) in a URL—will get readers to the relevant area within that page.

Initial capitalization: Wikipedia's MediaWiki software does not require that wikilinks begin with an upper-case character. Only capitalize the first letter where this is naturally called for, or when specifically referring to the linked article by its name:

Snakes are often venomous, but lizards only rarely (see Poison).

Piped links: The use of piped links can be avoided in many cases when adding a grammatical suffix to a wikilink that is not part of an article title, by placing the suffix outside the brackets. The suffix will still appear as part of the link, but will not be included in the link's target. For example, the markup [[transformer]]s appears in the article text as transformers, but links to the article Transformer.

External links

Articles can include an external links section at the end to list links to websites outside Wikipedia for the purpose of providing further information, as opposed to citing sources. The standard format is a primary heading named == External links == followed by a bulleted list of links. External links should identify the link and briefly summarize the website's contents, and why the website is relevant to the article. For example:

*[http://history.nih.gov/exhibits/history/index.html History of NIH]

*[http://www.nih.gov/ National Institutes of Health homepage]

When wikified, the link will appear as:

Refrain from using too many links in articles: a sea of speckled blue often looks messy.

Miscellaneous

Keep markup simple

Use the simplest markup to display information in a useful and comprehensible way. Markup may appear differently in different browsers. Use HTML and CSS markup sparingly and only with good reason. Minimizing markup in entries allows easier editing.

In particular, do not use the CSS float or line-height properties because they break rendering on some browsers when large fonts are used.

Formatting issues

တူဝ်ယေႃႈ: WP:MOSCOLOR

Formatting issues such as font size, blank space and color are issues for the Wikipedia site-wide style sheet and should not be dealt with in articles except in special cases. If you absolutely must specify a font size, use a relative size, that is, font-size: 80%; not an absolute size, for example, font-size: 8pt. It is also almost never a good idea to use other style changes, such as font family or color.

Typically, the use of custom font styles will

reduce consistency—the text will no longer look uniform with typical text;
reduce usability—it will likely be impossible for people with custom stylesheets (for accessibility reasons, for example) to override it, and it might clash with a different skin as well as bother people with color blindness; and
increase arguments—there is the possibility of other Wikipedians disagreeing with choice of font style and starting a debate about it for aesthetic purposes.

For such reasons, it is typically not good practice to apply inline CSS for font attributes in articles.

Color coding

Using color alone to convey information (color coding) should not be done. This is not accessible to people with color blindness (especially monochromacy), on black-and-white printouts, on older computer displays with fewer colors, on monochrome displays (PDAs, cell phones), and so on.

If it is necessary to use colors, try to choose colors that are unambiguous (such as orange and violet) when viewed by a person with red-green color blindness (the most common type). In general, this means that shades of red and green should not both be used as color codes in the same image. Viewing the page with Vischeck can help with deciding if the colors should be altered.

It is certainly desirable to use color as an aid for those who can see it, but the information should still be accessible without it.

Invisible comments

Editors use invisible comments to communicate with each other in the body of the text of an article. These comments are visible only in the wiki source (i.e. in edit mode), not in read mode.

Invisible comments are useful for flagging an issue or leaving instructions about part of the text, where this is more convenient than raising the matter on the talk page. They should be used judiciously, because they can clutter the wiki source for other editors. Check that your invisible comment does not change the formatting, such as introducing unwanted white space in read mode.

To leave an invisible comment, enclose the text you intend to be read only by editors within . For example:

Pronunciation

Pronunciation in Wikipedia is indicated using the International Phonetic Alphabet (IPA). For ease of understanding across dialects, fairly broad IPA transcriptions are usually provided for English pronunciations. See Help:Pronunciation (English) and Help:IPA (general) for keys, and {{IPA}} for templates that link to these keys. For English pronunciations, pronunciation respellings may be used in addition to the IPA.
