<div class="conjugation_explanation_title">Variable verbs (Context matters)</div>
<p>Some verbs can take either <span style="font-style: italic;">haben</span> or <span style="font-style: italic;">sein</span>. The rule is typically:</p>
<ul>
<li><strong>Sein:</strong> When the verb expresses the movement itself and has no direct object.</li>
<li><strong>Haben:</strong> When the verb has a <span class="brown_emphasis">direct object</span> (transitive usage).</li>
</ul>
<p>Here are common examples:</p>
