This magic word allows "=" to be used in unnamed template parameters, rather than being interpreted as the separator between the parameter name and value. It evaluates to the equals sign, =. Alternatively, the [[HTML]] entity "&amp;#61;" can be used if there is no need for it to be interpreted as wikimarkup, such as when the literal equals-sign is to be displayed to the user. Until June 2022, there was a template at this location with the same function, but it was replaced with a magic word for performance reasons in [[Phab:T91154]].

Do not use syntax like <code><nowiki>{{Template:=}}</nowiki></code>, and do not supply a parameter, for example <code><nowiki>{{=|foo}}</nowiki></code>. In those cases, the template transcludes as an error message: {{!xt|Error: The retired template <nowiki>{{=}}</nowiki> has been transcluded; see mw:Help:Magic words#Other for details. To fix this, use only the code <nowiki>{{=}}</nowiki> to generate the &#61; character.}}

Do not use the magic word in URLs rather use [[percent-encoding]] or no encoding:
*Wrong: <code><nowiki>https://example.com/?arg{{=}}789</nowiki></code>
*Correct: <code><nowiki>https://example.com/?arg%3D789</nowiki></code>
*Correct: <code><nowiki>https://example.com/?arg=789</nowiki></code>

== Usage ==
* <code><nowiki>{{Font color|black|yellow|2 + 2 {{=}} 4}}</nowiki></code> produces: {{Font color|black|yellow|2 + 2 {{=}} 4}}

You can also use named parameters to bypass the restriction:
* <code><nowiki>{{Font color|black|yellow|3= 2 + 2 = 4}}</nowiki></code> produces: {{Font color|black|yellow|3= 2 + 2 = 4}}

Unlike <code>&amp;#61;</code>, the magic word only delays the interpretation of the symbol as code:
<syntaxhighlight lang="html">
{{concat|<div style{{=}}"font-style:italic">This should be italicised.</div>}}
{{concat|<div style&#61;"font-style:italic">This will not be italicised.</div>}}
</syntaxhighlight>
produces:
{{concat|<div style{{=}}"font-style:italic">This should be italicised.</div>}}
{{concat|<div style&#61;"font-style:italic">This will not be italicised.</div>}}
