+<h2>Translating Field Names</h2>
+
+<p>If you would like to store the "human" name you passed to the <dfn>set_rules()</dfn> function in a language file, and therefore make the name able to be translated, here's how:</p>
+
+<p>First, prefix your "human" name with <dfn>lang:</dfn>, as in this example:</p>
+
+<code>
+$this->form_validation->set_rules('first_name', '<kbd>lang:</kbd>first_name', 'required');<br />
+</code>
+
+<p>Then, store the name in one of your language file arrays (without the prefix):</p>
+
+<code>$lang['first_name'] = 'First Name';</code>
+
+<p><strong>Note:</strong> If you store your array item in a language file that is not loaded automatically by CI, you'll need to remember to load it in your controller using:</p>
+
+<code>$this->lang->load('file_name');</code>
+
+<p>See the <a href="language.html">Language Class</a> page for more info regarding language files.</p>
