This page,Help:Punctuation, explains the use ofpunctuation marks in Wikipedia pages. In general, pages can contain the type of punctuation marks used in major English style guides. However, some characters entered into column 1 of a line, or combinations of punctuation characters, have special meanings as markup directives to perform extra text formatting.
Ampersand is a prefix to accessentities in Wiki code, just like in HTML. Ampersand itself should be encoded as& to avoid possible syntactic interference.
The typewriterapostrophe', along with its use as a (single)quotation mark, also encodesitalic text''...'' orboldface text'''...''' orbold italic text'''''...'''''.
A leadingasterisk*, in column 1 of a line, denotes the start of an indentedbulleted list. The bulleted list can be indented further by prepending other asterisks colon** or two*** or three**** (etc.), for more indentation, each of which creates a newunordered list.Template:Indent and similar templates offer an accessible-friendly means of creating visual indentations without changing the bullet appearance.
The double-braces, orcurly brackets{{ }}, are used to denote a markup function, variable, or template call (such as{{convert|7|km|mi}}. Within template definitions, triple braces allow a template to refer to one of its parameters (such as parameter 1{{{1}}}).
The singlesquare brackets[ ] are used to link to an external website, with theURL address in brackets (such as[http://www.google.com Google]). More often, the double-bracket notation[[ ]] is used to denote awp:wikilink (orhyperlink) connecting to another page. See also:{{Bracket}} andWikipedia:Manual of Style#Brackets and parentheses.
A leading colon: on a line causes the line to be displayed as the value part of adescription list.
Whenlinking to category pages, it prevents the current page from becoming a member of the linked category -- seeColon trick for further information.
Dashes (such as anen dash–, which can be coded by–, and a longerem dash—, which can be coded by—) are punctuation marks with a variety of uses in English typography; seeMOS:DASH.
Thehyphen-minus-, also known as the keyboard hyphen and keyboard stroke, has several uses along its role as a word joiner. A separate line of 4 hyphens---- causes a horizontal-rule line to display. Also, a pipe-stroke, orvertical bar with hyphen|- denotes a row inside awp:wikitable. The use of hyphens as a substitute for dashes is substandard in English Wikipedia; seeMOS:HYPHEN.
The hyphen-minus is used as a minus sign in computer programming languages, and in math mode, but in text, the proper typographical symbol for negation or subtraction is the minus sign, available in the "Special characters" dropdown of the edit pane among the "Symbols" in the list ≥ ± − × ÷ ← → · § ‽ where the third character is the "minus". Minus signs may also be coded by−.
Another kind ofhyphen is thenon‑breaking hyphen, available in the Wiki code as{{nbhyph}}. This character has the sole purpose to be a non-breaking word joiner.
Unlike the hyphen-minus, the dashes and minus sign do not have any special role in the MediaWiki markup language.
Like in HTML code,< > are used in Wiki code fortags. That's why< sometimes needs to be written as<.
A pipe symbol, orvertical bar|, is used for several purposes. Inside a wikilink, the bar separates the link from the displayed anchor text (such as[[boat anchor|anchor]]). In a template call, the bar separates parameters from each other. In awp:wikitable, a brace with vertical bar begins a table{|, a lone bar denotes a column cell, and a bar-hyphen|- denotes another row in the table. A wikitable ends with the bar-brace token|}.
A leadingpound sign#, in column 1 of a line, causes the line to be displayed as an auto-numbered line in a list of numbered entries.The numbered line can be indented further by prepending a pound sign## or two### or three#### or such, for more indentation, each of which creates a new enumerated list.Template:Indent and other templates offer an accessible-friendly means of creating visual indentations without creating other lists.
A leadingsemicolon;, in column 1 of a line, causes the line to be displayed as the name part of adescription list. These lists contain a name, followed by one or more descriptions that apply to it (e.g. in a glossary). These descriptions are indicated by starting them with:. Although most browsers will display the name term in boldface, this should not be used to createartificial headings foraccessibility reasons.
