{{documentation subpage}}
This template is for having shorter links to an English Wikipedia article when the link is identical to its label. It takes the following parameters:

* {{para|1|req=1}} – the page title on Wikipedia to which you wish to link
* {{para|2}} – the text that the template displays. Default is the value entered in {{para|1}}
* {{para|lang}} – the ISO language code of the target Wikipedia. Default is <code>en</code>, for English.

A similar effect can be accomplished using the [[w:Help:Pipe trick|pipe trick]]: <code>[[w:Chicken&#124;]]</code> is converted to <code>[[w:Chicken&#124;Chicken]]</code> during the pre-save transform, which renders as [[w:Chicken|Chicken]]. Only one interwiki prefix can be stripped in this way. <code>[[w:fr:Académie française&#124;]]</code> transforms to <code>[[w:fr:Académie française&#124;fr:Académie française]]</code>.

See also [[Template:wikipedia]], which inserts a box with a link to the Wikipedia article, and has no required parameters.

===Examples===
* just using parameter 1 – {{temp|w|The History of the Decline and Fall of the Roman Empire}} gives: {{w|The History of the Decline and Fall of the Roman Empire}}
* using parameters 1 and 2 – {{temp|w|William Shakespeare|Shakespeare}} gives: {{w|William Shakespeare|Shakespeare}}
* also using parameter lang – {{temp|w|William Shakespeare|Shakespeare|lang=fr}} gives: {{w|William Shakespeare|Shakespeare|lang=fr}} (linking to the French Wikipedia article)

===Notes===
Because of its simplicity, the template can be substituted using <code>subst:</code>
* {{temp|subst:w|William Shakespeare|Shakespeare}} gives: <code>[[w:William Shakespeare&#124;Shakespeare]]</code>

However, substituting {{temp|subst:w|The History of the Decline and Fall of the Roman Empire}} gives an unwieldy duplication of content the template is here to avoid in the first place: <code>[[w:The History of the Decline and Fall of the Roman Empire&#124;The History of the Decline and Fall of the Roman Empire]]</code>
