{{Language templates}}

This template links conditionally to pages on non-English Wikipedias. If the specified article {{em|does not exist}} on the English Wikipedia, this template {{em|intentionally}} displays a red link to that anticipated but still-nonexistent article, followed by link(s) to the specified article(s) on the non-English Wikipedia(s), shown under the corresponding [[language code]](s), in brackets. Hovering over a non-English link displays the name of the article on the non-English Wikipedia, as normal. Links to non-English Wikipedia articles are always blue; it is up to the editor to make sure they link to the intended article.

If the specified article {{em|exists}} (that is, after the anticipated article has been created) on the English Wikipedia, this template will only show the blue link to that article, and no longer to the non-English link(s).{{efn|name=preserve|Use {{para|preserve}} or its alias {{para|display}} to show the language links even if the English Wikipedia page exists. Using either parameter also eliminates the expensive parser function call. {{U|Cewbot}} will NOT convert this template into a regular link if either parameter is set. Cewbot will also not convert this template into a regular link if the English Wikipedia page exists but is a redirect back to the same page where the template appears.}}

Because {{tl|ill}} normally produces a working link along with a redlink, it is appropriate for use in hatnotes, in spite of the general advice to avoid redlinks in hatnotes.{{efn|Discussed [[Template talk:Interlanguage link#Use in hatnotes|in 2022]].}}

Please be aware [[:User:Cewbot|Cewbot]] '''removes''' this template when it detects the target article has been created on English Wikipedia, converting {{tl|ill}} links to regular (blue) links.{{efn|name=preserve}}

{{see also|Wikipedia:Database reports/Interlanguage link templates need to fix}}

==Usage==
There are several ways of using this template. It can produce links to one or more specific languages, [[User:Magnus Manske|Magnus Manske]]'s [https://tools.wmflabs.org/reasonator/ Reasonator], or to the Wikidata table of languages.

The shortcut {{tl|ill}} may be used.

A full list of language codes can be found at {{section link|List of Wikipedias|Active editions}}.

{{As of|2016|2}}, if there is a redirect for the term in English Wikipedia, both the redirected (blue) link and interlanguage link(s) are displayed. This is why "casa" appears as a bluelink in the example [[#Link to multiple languages|below]].

Where there are multiple interlanguage links readers may be confused about their purpose. The template {{tl|interlanguage link info}} may be placed at the head of a page or section.

==Link to one foreign language==
To link to a foreign language article with the {{em|same}} title as the English Wikipedia, the parameters are:

{{tlc|ill|''Article title''|''language code''}}
*{{tlc|ill|Hanning Schröder|de}} produces: {{ {{PAGENAMETDOC}}|Hanning Schröder|de}} (the English article exists),
whereas 
*{{tlc|ill|Richard J. Youle|de}} produces: {{ {{PAGENAMETDOC}}|Richard J. Youle|de}} (as of June 2022, no English article exists)

To link to a foreign language article with a {{em|different}} title, the parameters are:

{{tlc|ill|''English article title''|''language code''|''Title in foreign language''}}
*{{tlc|ill|Hooglede town hall|nl|Gemeentehuis van Hooglede}} produces: {{ {{PAGENAMETDOC}}|Hooglede town hall|nl|Gemeentehuis van Hooglede}}

==Link to multiple languages==
To link to multiple languages with the same title as the English language page, the titles of the page are not necessary; the parameters are:

<code>{{((}}ill|''English article title''|''language 1 code''||''language 2 code''||...}}</code>
* for example <code><nowiki>{{ill|casa|es||it||ro||de|haus}}</nowiki></code> produces: {{ {{PAGENAMETDOC}}|casa|es||it||ro||de|haus}}

Note: As of February 2016, [[casa]] above is a redirect. Redirects appear as blue links even while foreign-language links are still shown.

To link to multiple language articles, the parameters are:

{{tlc|ill|''English article title''|''language 1 code''|''Title in language 1''|''language 2 code''|''Title in language 2''|...}}

* for example {{tlc|ill|Olena Chaplynska|uk|Олена Чаплинська|ru|Чаплинская, Гелена|ja|モトローナ・チャプリーンシカ}} produces: {{ {{PAGENAMETDOC}}|Olena Chaplynska|uk|Олена Чаплинська|ru|Чаплинская, Гелена|ja|モトローナ・チャプリーンシカ}}

==Modifying the display==
===Displaying different text===
To create a [[WP:piped link|piped link]] (text displayed that is different from the title of the page to which the text links), use the {{para|lt}} parameter (which stands for "link text"). This is useful if [[WP:disambiguation|disambiguation]] is necessary, for example to hide the (botanist) in [[Charles Darwin (botanist)]]:
* {{tlx|ill|Charles Darwin (botanist)|lt{{=}}Charles Darwin|fr|Charles Darwin|de|Charles Darwin|es|Charles Darwin}} produces: {{ {{PAGENAMETDOC}}|Charles Darwin (botanist)|lt=Charles Darwin|fr|Charles Darwin|de|Charles Darwin|es|Charles Darwin}}

'''Do not''' use {{tlf|!}} to create piped links, as doing so will prevent the foreign language links from disappearing if an English article is created:

{{!xt|{{tlx|ill|Maze (band){{tlf|!}}Mazy|...}}}} is not equivalent to {{xt|{{tlx|ill|Maze (band)|lt{{=}}Mazy|...}}}}.

===Forcing links===
To display the interlanguage links even if the English Wikipedia article exists, add any of the values <code>1</code>, <code>y</code>, <code>yes</code> or <code>force</code> for the parameter {{para|display}} or its alias, {{para|preserve}}.{{efn|name=preserve}}

{| class="wikitable"
|-
! Input !! Output
|-
| <code><nowiki>{{ill|Joke|fr|Blague|hu|Vicc|de|Witz}}</nowiki></code> || {{ {{PAGENAMETDOC}}|Joke|fr|Blague|hu|Vicc|de|Witz}}
|-
| <code><nowiki>{{ill|Joke|fr|Blague|hu|Vicc|de|Witz|display=1}}</nowiki></code> || {{ {{PAGENAMETDOC}}|Joke|fr|Blague|hu|Vicc|de|Witz|display=1}}
|}

{{em|This feature should not be used in articles under most circumstances. However, in pages that are primarily lists of pages that link to the same language, it might be desirable all links on a page should link to other languages whether or not an English page exists. This feature can also be used as a work-around to eliminate [[WP:EXPENSIVE|expensive parser function calls.]]}}

Note: As of February 2016, redirects appear as blue links even while foreign-language links are still shown (i.e. you do not need to force-show them).

===Remove bold formatting from links===
Usually the display of the Interlanguage or Wikidata or the Reasonator (the "appended link") are in normal font, but if the appended link is for example in a title line of table, then along with the rest of the line the appended link will be bold. In such circumstances the appended link can be set to display unbolded by adding any value for the parameter {{para|nobold}}.

{| class="wikitable"
|-
! Input !! Output
|-
| <code><nowiki>'''{{ill|Charles Darwin (botanist)|fr|Charles Darwin|de|Charles Darwin}}'''</nowiki></code> || '''{{ {{PAGENAMETDOC}}|Charles Darwin (botanist)|fr|Charles Darwin|de|Charles Darwin}}'''
|-
| <code><nowiki>'''{{ill|nobold=1|Charles Darwin (botanist)|fr|Charles Darwin|de|Charles Darwin}}'''</nowiki></code> || '''{{ {{PAGENAMETDOC}}|nobold=1|Charles Darwin (botanist)|fr|Charles Darwin|de|Charles Darwin}}'''
|}

===Italics and quotation marks===
If the linked material should be in italics (e.g., it is a major work such as a film title), use {{para|italic|y}} (or {{para|italic|yes}}, etc.) to generate italic markup around the link but not around the square-bracketed inter-language links.{{tnull|ill|Un papillon sur l'épaule|fr|italic{{=}}y}} produces: {{ill|Un papillon sur l'épaule|fr|italic=y}}

If the linked material should have quotation marks around it (e.g., it is a minor work such as a song title), use {{para|quote|y}} (or {{para|quote|yes}}, etc.) to generate them around the link, but not around the square-bracketed inter-language links, and not themselves part of the link. This only does double quotation marks: {{tnull|ill|Maman ne le sait pas|fr|quote{{=}}y}} produces: {{ill|Maman ne le sait pas|fr|quote=y}}

If both are used, quotation marks will appear around an italicized title, without italicizing the quotation marks.

===Punctuation before language links===
If punctuation such as a comma or period/full stop follows the expression, you may wish to display the punctuation before the interlanguage link(s), especially if combining it with superscript display. So, rather than have:
: ...the French concept of {{ill|freedom of instruction|fr|Liberté d'enseignement|v=sup}}.
which awkwardly displays the sentence-final punctuation after the French link, you can display it before:
: ...the French concept of {{ill|freedom of instruction|fr|Liberté d'enseignement|lt=freedom of instruction.|v=sup}}
The second example above is achieved simply by borrowing the {{para|lt}} parameter, and including the punctuation in it, like this:
: {{tlc|ill|freedom of instruction|fr|Liberté d'enseignement|lt{{=}}freedom of instruction.|v{{=}}sup}}

===Vertical alignment===

The vertical alignment of the interlanguage/Wikidata/Reasonator links can be altered by adding:
*<code><nowiki>vertical-align=sup</nowiki></code> to place the links in superscript
*<code><nowiki>vertical-align=sub</nowiki></code> to place the links in subscript

The parameter aliases {{para|valign}} or {{para|v}} may be used instead.

{| class="wikitable"
|-
! Input !! Output
|-
| <code><nowiki>{{ill|Charles Darwin (botanist)|fr|Charles Darwin|de|Charles Darwin|vertical-align=sup}}</nowiki></code> || {{ {{PAGENAMETDOC}}|Charles Darwin (botanist)|fr|Charles Darwin|de|Charles Darwin|vertical-align=sup}}
|-
| <code><nowiki>{{ill|Charles Darwin (botanist)|fr|Charles Darwin|de|Charles Darwin|valign=sub}}</nowiki></code> || {{ {{PAGENAMETDOC}}|Charles Darwin (botanist)|fr|Charles Darwin|de|Charles Darwin|valign=sub}}
|-
| <code><nowiki>{{ill|Charles Darwin (botanist)|fr|Charles Darwin|de|Charles Darwin|v=sup}}</nowiki></code> || {{ {{PAGENAMETDOC}}|Charles Darwin (botanist)|fr|Charles Darwin|de|Charles Darwin|v=sup}}
|}

===Infobox font size===
When this template is placed within elements that already use a smaller font size, such as infoboxes, the interlanguage link drops below 85% of the page's default font size. To prevent this and adhere to [[MOS:SMALLTEXT]] the value <code>ib</code> can be used with the vertical alignment parameter: <code>vertical-align=ib</code> (or <code>v=ib</code>, etc.)

{| class="wikitable"
|-
! Input !! Output
|-
| <code><nowiki>{{ill|Charles Darwin (botanist)|fr|Charles Darwin|de|Charles Darwin|v=ib}}</nowiki></code> || {{ {{PAGENAMETDOC}}|Charles Darwin (botanist)|fr|Charles Darwin|de|Charles Darwin|v=ib}}
|}

''This feature should only be used when the template is placed within infoboxes or other elements that use a smaller font size.''

==Link to Reasonator and Wikidata==
To link to the Wikidata table of languages in which the article is available, the parameters are:

{{tlc|ill|''Article title in English Wikipedia''|WD{{=}}''Wikidata item code''}}
* {{tlc|ill|Jokery|WD{{=}}Q131138}} produces: {{ {{PAGENAMETDOC}}|Jokery|WD=Q131138}}
All links to other Wikipedias are ignored if {{para|WD}} is present.

To link to [https://tools.wmflabs.org/reasonator/ Reasonator], add any value for the parameter {{para|reasonator}}. If a Wikidata item is linked, then the Reasonator link goes to the page for that item; if not, then a search is performed on Reasonator for that item.
{| class="wikitable"
|-
! Input !! Output
|-
| <code><nowiki>{{ill|Jokery|WD=Q131138|reasonator=1}}</nowiki></code> || {{ {{PAGENAMETDOC}}|Jokery|WD=Q131138|reasonator=1}}
|-
| <code><nowiki>{{ill|Jokery|reasonator=1}}</nowiki></code> || {{ {{PAGENAMETDOC}}|Jokery|reasonator=1}}
|}

To display Wikidata link as "d", add any value for the parameter {{para|short}} or its alias, {{para|s}}:
* {{tlc|ill|Jokery|wd{{=}}Q131138|s{{=}}1|v{{=}}sup}} produces: {{ {{PAGENAMETDOC}}|Jokery|wd=Q131138|s=1|v=sup}}

==Automatic removal==
If you create an {{tl|interlanguage link}} and an English Wikipedia article is later created, this template will appear as a regular (blue) link as explained [[#top|above]]. The underlying template, however, will eventually be edited automatically (it is one of the tasks assigned to bot [[:User:Cewbot|Cewbot]]), removing the template and resulting in a regular (blue) link. While this is intended to save on the computational load, it does mean users will '''not''' again be directed to the foreign-language article if the article is later deleted as this information is lost. The link will become a [[WP:REDLINK|red link]]. Use {{para|preserve}} or {{para|display}} to prevent automatic removal.{{efn|name=preserve}}

==Limitations==

=== Non-existent foreign article ===
On Wikipedia, links to nonexistent pages normally show as [[WP:REDLINK|red links]]. There is no way for this template, or any code on Wikipedia, to check [[mw:Help:Extension:ParserFunctions##ifexist|whether an article on another language's Wikipedia exists]]. Links to all foreign-language articles, including nonexistent foreign-language articles, show as blue links.

=== Interactions with other templates ===

This template may interact unfavorably with the {{tl|lang}} template. For example, the following code will not work in article space (it works on talk and some other types of pages):
* <code><nowiki>{{ill|Machsor Lipsiae|de|lt={{lang|he-LA|Machsor Lipsiae}}}}</nowiki></code> → {{ill|Machsor Lipsiae|de|lt={{lang|he-LA|Machsor Lipsiae}}}}
For an alternative way to code this that works in all namespaces, please see [[Template:Lang#Links]]. [[User:Mathglot|Mathglot]] ([[User talk:Mathglot|talk]]) 02:57, 27 January 2024 (UTC)

==Examples==
* <code><nowiki>{{ill|TC Matic|af|TC Matic|nl|TC Matic|fr|TC Matic|es|TC Matic}}</nowiki></code> produces: {{ {{PAGENAMETDOC}}|TC Matic|af|TC Matic|nl|TC Matic|fr|TC Matic|es|TC Matic}}, because [[TC Matic]] exists here
* <code><nowiki>{{ill|TC Matic (band)|af|TC Matic|nl|TC Matic|fr|TC Matic|es|TC Matic}}</nowiki></code> produces: {{ {{PAGENAMETDOC}}|TC Matic (band)|af|TC Matic|nl|TC Matic|fr|TC Matic|es|TC Matic}}, because [[TC Matic (band)]] does not exist here
* <code><nowiki>{{ill|TC Matic (band)|af||nl||fr||es|}}</nowiki></code> produces: {{ {{PAGENAMETDOC}}|TC Matic (band)|af||nl||fr||es|}} – although shown in blue the interwiki links won't work because they default to the title "TC Matic (band)" which is wrong
* <code><nowiki>{{ill|TC Matic (band)|lt=TC Matic|af|TC Matic|nl|TC Matic|fr|TC Matic|es|TC Matic}}</nowiki></code> produces: {{ {{PAGENAMETDOC}}|TC Matic (band)|lt=TC Matic|af|TC Matic|nl|TC Matic|fr|TC Matic|es|TC Matic}} – the text "TC Matic" now redlinks to "TC Matic (band)"
* <code><nowiki>{{ill|TC Matic|lt=TC Matic (band)|af|TC Matic|nl|TC Matic|fr|TC Matic|es|TC Matic}}</nowiki></code> produces: {{ {{PAGENAMETDOC}}|TC Matic|lt=TC Matic (band)|af|TC Matic|nl|TC Matic|fr|TC Matic|es|TC Matic}} – the text "TC Matic (band)" now links to "TC Matic" which exists
