<term>

Definition List: Term

Word, phrase, graphic, chemical structure, equation, or other noun that is being defined or described.

This element is typically used in conjunction with a definition in a definition list (two-part list). The term occupies the first column of the two-part list and is the subject of the definition or description, which occupies the second column.

Related Elements

A <def-list> may take a <label> that provides it with a number or other designator, followed by an optional <title> naming the entire list, followed by optional headings for terms and their definitions. <term-head> contains the heading over the first (term) column, and <def-head> contains the heading for the second (definition) column; neither serves as a container element for terms or definitions. Individual <term>s and their <def>s are paired in <def-item>s. Definition lists are recursive, so following all the terms and definitions, there may be one or more embedded <def-list> elements.
