Interlanguage links are links from any page (most notably articles) in one Wikipedia language to one or more nearly equivalent or exactly equivalent pages in another Wikipedia language, between language versions of Wiktionary, and the same within Wikisource, Wikiquote, and Wikibooks.

The interlanguage link feature works also on Commons, and produces links to the Wikipedias. This is not reciprocal: a link from a Wikipedia to Commons is an in-page link. They appear at one or two edges of the webpage (in Monobook on the left, in Classic at the top and bottom) after Languages, and show the names of languages for which a link is available. Interlanguage links look like external links (or different, depending on CSS), but the syntax is more like internal links. They are a form of interwiki links.

Contents

Syntax

The interlanguage links take the following form:

[[language code:Title]]

where the language code is the two-letter code as per ISO 639-1. (See Complete list of language Wikipedias available. English is "en", German is "de", etc.) So for example in the English language article on Plankton, which is available on many other wikis, the interlanguage links might look like this:

[[ar:عوالق]]
[[de:Plankton]]
[[eo:Planktono]]
[[es:Plancton]]
[[fr:Plancton]]
[[nl:Plankton]]
[[ja:プランクトン]]
[[ko:플랑크톤]]
[[pl:Plankton]]
[[ru:Планктон]]
[[simple:Plankton]]
[[zh:浮游生物界]]

NOTE: These links are treated specially, and don't show up in the body of the text, but in a special sidebar section "in other languages" listed by language name. Technically they can go anywhere in the article source; placement does not alter the visual appearance of the links on the rendered page except for the order. However, the convention is to put them at the bottom of the wikitext.

You should not include the link to the language in which you are writing.

To create an inline link (a clickable link within the text), see the section Inline interlanguage links below.

To mark one or more of these links as a featured article in a specific language, just add the Template:Link FA below right before the interlanguage links:

{{Link FA|language code}}

For example, if the Tomato article is a featured one in French and German, you should write:

{{Link FA|fr}} {{Link FA|de}}

[edit] Bots and links to and from a section

Various bots add and attempt to correct interlanguage links: if A links to B, B will be linked to A, and if A links to B and B to C, A will be linked to C. The downside is that an error in an interlanguage link in one Wikipedia propagates to other Wikipedias. Thus if a bot produces a wrong result one may have to search for the underlying error in another language version of Wikipedia.

The activity of the bots also requires that interlanguage links are only put from an article to an article covering the same subject, not more and not less. It is technically possible to make an interlanguage link from an article to a section of an article, just like any link to a section. The bots can handle this. They will not try to link back from a section to the article that links to it. Maintaining such a link by hand, however, is complicated, so linking to a section is still not recommended.

If interwiki bots persistently add an interwiki link that human editors consider wrong, it is no use revert-warring against the bots: they won't understand and will always add the link back in. A simple solution is not to remove the offending link, but to enclose it in html comment marks ("<!-- [[ex:Example]] -->"). The bots understand this convention and will not re-add a link marked in this way.

[edit] Specific languages

[edit] Hebrew and Russian

In the Hebrew Wikipedia there is a thorough project to add relevant interwiki links to all possible pages and categories or to mark them as unlikely to need an interwiki link (for example, disambiguation pages for Hebrew-only homographs). If you know Hebrew and want to help the project or if you want to learn from our experience and apply it to the Wikipedia in your language:

[edit] Chinese

In the past the Chinese Wikipedia had two versions of many articles written in Simplified and Traditional script. Nowadays the conversion between the scripts is made automatically, so there is no need for linking script-specific versions of articles. Please take a few moments to read Wikipedia:Chinese interlanguage links to avoid unnecessary extra work.
