Verbs that are affected by this spelling change include verbs whose stem end in a vowel (exceptions: verbs ending in <span style="font-style: italic;">-guir</span>, e.g. <span style="font-style: italic;">seguir</span>; verbs ending in <span style="font-style: italic;">-quir</span>, e.g. <span style="font-style: italic;">delinquir</span>).</p>
