< abbr>

If you use an abbreviation or an acronym, then the < abbr> element can be used. A title attribute on the opening tag is used to specify the full term.
In HTML 4 there was a separate < acronym> element for acronyms. To spell out the full form of the acronym, the title attribute was used (as with the < abbr> element above). HTML5 just uses the < abbr> element for both abbreviations and acronyms.
