Abbreviations are shortened forms of words or phrases that are commonly used in written communication. In HTML, several elements can be used to represent abbreviations and provide additional context or meaning to the content:

The <abbr> element represents an abbreviation or acronym. It can provide the complete form of a shortened word or phrase, typically when the abbreviation is first used in a document.

Note

An acronym is a word formed from the initial letters of a name or phrase, such as NASA or AIDS.

The <acronym> element is similar to the <abbr> element but is intended explicitly for acronyms.
