The acronym tag is used to define an acronym. An optional title attribute can be used to specify the expansion for the acronym.

The <acronym> tag has been removed in HTML 5. Use <abbr> tag instead.

Expansion of the acronym (what you specify in the title attribute) is shown when you bring mouse over it.
