<p>L'<em>Element HTML Definició</em> (&lt;dfn&gt;) representa la instància de definició d'un terme.</p>

<div class="note"><strong>Notes d'ùs en HTML5:</strong>

<ul>
 <li>L'element &lt;<code>dfn</code>&gt; indica el terme definit; la definició del terme ve determinat  per {{HTMLElement("p")}}, {{HTMLElement("section")}} o grup de llista de definicions circumdant (normalment un parell {{HTMLElement("dt")}}, {{HTMLElement("dd")}}).</li>
 <li><span id="result_box" lang="ca"><span>El valor</span> <span>exacte del</span> <span>terme que</span> <span>es</span> <span>defineix és</span> <span>determinat</span> <span>per les</span> <span>regles següents:</span></span>
  <ol>
   <li>Si l'element &lt;<code>dfn</code>&gt; té un atribut <strong><code>title</code></strong>, llavors el terme és el valor d'aquest atribut.</li>
   <li>Ara bé, si només conté un element {{HTMLElement("abbr")}} amb un atribut {{htmlattrxref("title", "abbr")}}, llavors el terme és el valor d'aquest atribut.</li>
   <li>Altrament, el contingut del text de l'element &lt;<code>dnf</code>&gt; és el terme definit.</li>
