The template {{Abbr}} is used to write an abbreviation with its meaning. It is a front-end for the HTML element <abbr>...</abbr>, the element used by most web browsers to create a tooltip indicating the meaning of an abbreviation or acronym.

Please note: Do not use {{abbr}} or <abbr> to mark up material other than abbreviations or acronyms. Using it to generate tooltips elsewhere is a misuse of the underlying HTML and causes accessibility problems.


The template {{abbr}} takes two unnamed parameters, in order:

  • abbreviation: The abbreviation; shows as text.
  • meaning: The meaning; shows as the tooltip.

A third unnamed parameter accepts the following values:

Named parameters:

  • class: Adds a CSS class.
  • id: Adds a HTML id; this must be unique on the entire page.
  • style: Adds a style attribute.


Markup Renders as
{{abbr|MSLP|Mean Sea Level Pressure}}


When hovering over the text "MSLP", something like Mean Sea Level Pressure will appear as a tooltip in most browsers. Popular screen readers, used by visually impaired readers, give the meaning in a different way.

Markup Renders as
{{abbr|UK|United Kingdom|class=country-name|id=foobar}}
