A Wikipedia '''namespace''' is a set of Wikipedia pages whose [[Help:page name|names]] begin with a particular reserved word recognized by the [[MediaWiki]] software (followed by a colon). For example, in the ''user namespace'' all titles begin with the prefix ''User:''. In the case of the article (or main) namespace, in which encyclopedia articles appear, the reserved word and colon are absent. (Note: main space articles can optionally include a colon at the beginning with no reserved word, so <code>[<nowiki/>[Article]]</code> and <code>[<nowiki/>[:Article]]</code> are equivalent. This is usually only necessary for the advanced technique of [[WP:Transclusion|transcluding]] a main space article into another page.)

The aliases '''WP''' for '''Wikipedia''', and '''WT''' for '''Wikipedia&nbsp;talk''', work for page names in the search box, and making links as well as inclusions. See [[#Aliases|Aliases]] below for other aliases. (The pseudo-namespaces such as '''H''' for '''Help''', and '''CAT''' for '''Category''', are extremely limited. See ''[[#Pseudo-namespaces|Pseudo-namespaces]]'' below.)

* '''[[Wikipedia:Module namespace|Module namespace]]''' (prefix '''Module:'''): contains [[mw:Extension:Scribunto|Scribunto]] modules&nbsp;– Lua scripts implementing special-purpose [[mw:Manual:Parser functions|parser functions]] for use in templates, beyond the [[Help:Magic words#Parser functions|basic set]] included with MediaWiki and its [[mw:Extensions FAQ|extensions]].

* '''Gadget namespace''' (prefix '''Gadget:'''): installed but not currently in use.<ref>[[Wikipedia:Village pump (technical)/Archive 139#New "Gadget:" and "Gadget definition:" namespaces?]]</ref> [[Wikipedia:Gadget|Gadgets]], which are small [[Snippet (programming)|snippets]] enabled in [[Special:Preferences#mw-prefsection-gadgets|user preferences]], currently use the [[Help:MediaWiki namespace|Mediawiki namespace]] with the ''MediaWiki:Gadget-'' page name prefix. It is a [[mw:Manual:Using custom namespaces|custom namespace]] installed by the [[mw:Extension:Gadgets|Gadget extension]].

* '''Gadget definition namespace''' (prefix '''Gadget definition:'''): installed but not currently in use; see above for more information. Gadget definitions currently use the [[MediaWiki:Gadgets-definition]] page.

===Not installed===

On [[MediaWiki]] installations other than the English Wikipedia, additional namespaces may be installed by [[mw:Manual:Extensions|MediaWiki extension]]s; the list of default IDs for these namespaces is at [[mw:Extension default namespaces|Extension default namespaces]].

===Aliases and pseudo-namespaces===

=== Special ===

{{main|Help:Special page}}

You can create a [[Wikipedia:redirect|redirect]] to a Special page, but the redirect will not be followed automatically.

To learn some of these shortcuts, first follow the pseudo-namespace link above, then follow one of the redirects listed on that page. It will take you to the target, where you then notice any {{tl|shortcut}} boxes to the right of the page, which may also list some additional shortcuts to that same area. By observing these steps repeatedly, you can discover ways to shorten your typing. You will use pseudo-namespace names more often if you are an advanced editor, highly active in many namespaces, or constantly linking to pages that have a pseudo-namespace shorcut.

As a final example, every [[Wikimedia Foundation]] project has a "[[m:Help:Transwiki|Transwiki:]]" pseudo-namespace (sometimes a real namespace) for importing articles manually. A wiki project that would manually move many pages between [[wp:sister|sister projects]] uses this tag. Redirects/shortcuts are not directly involved here, as described above. Instead the page title is [[WP:move|move]]d to "Transwiki:''namespace:pagename''", and that content is then copied and pasted into a new page name of that temporary title on the target wiki. When it is accepted the title is then moved out of the '''Transwiki''' pseudo-namespace there and becomes a real page name in its respective namespace.

Important points to note:

When making links to other language Wikipedias, add an initial colon if you want the link to appear inline rather than in the skin's sidebar under "Languages"; see [[Help:Colon trick]] for an explanation. So <code><nowiki>[[:de:Internet]]</nowiki></code> is an inline link to "[[:de:Internet|Internet]]" in the German Wikipedia; but if using an interwiki prefix this is unnecessary, for example <code><nowiki>[[w:de:Internet]]</nowiki></code> is the same inline link.

* Change the functionality of <kbd><nowiki>{{</nowiki>[[WP:Transclusion|pagename]]<nowiki>}}</nowiki></kbd> so that it defaults to the set of pagenames in '''Template'''.

* Tailor ''[[Wikipedia:Edit notices|edit notices]]'' to a particular namespace's edit page, informing an editor of certain aspects about the content of that namespace.

The namespace functionality is often visible in the URL, where you will see a namespace number. These are given in the table below.

All namespaces with a positive number or zero in this list are searchable. Specifically, the {{ns:-2}} and {{ns:-1}} namespaces are not searchable.
