The dt element encapsulates a term in a definition list.

dl is a definition list.

dt is a definition term.

dfn is a definition.

dd is a definition description.

* See note below regarding dt vs. dfn

A live example:


Router
A device used to deliver packets between computer networks.
DNS
A protocol to convert between domain names and IP addresses.

Does my router support DNS?


* If the definition term (dt) contains additional text around the term, then the dfn element should encapsulate only the word or words being defined.
E.g.


 <dt>
     The <dfn>TCP/IP</dfn> protocol
 </dt>
