Which auxiliary verb to use for 'potere'?
<p>The verb
<a class="conjugation_explanation_link_intext verb_link" href="/study/conjugations/ita/potere/" title="Click to see conjugations for potere" target="_blank">potere</a>
(<span style="font-style: italic;">to be able to, can</span>) is a <strong>modal verb</strong> (or <span style="font-style: italic;">verbo servile</span>). Like<a class="conjugation_explanation_link_intext" href="/conjugationExplanation/italian_auxiliary_verb_dovere/" target="_blank">dovere</a>
and<a class="conjugation_explanation_link_intext" href="/conjugationExplanation/italian_auxiliary_verb_volere/" target="_blank">volere</a>
, its choice of auxiliary verb in compound tenses usually depends on the <strong>main verb</strong> that acts as the infinitive.</p><div class="conjugation_explanation_title">General Rule: The Chameleon Effect</div>
<p>Think of <span style="font-style: italic;">potere</span> as a chameleon: it takes the "color" (the auxiliary verb) of the verb it serves. If the main verb uses
<a class="conjugation_explanation_link_intext verb_link" href="/study/conjugations/ita/avere/" title="Click to see conjugations for avere" target="_blank">avere</a>
, then <span style="font-style: italic;">potere</span> uses <span style="font-style: italic;">avere</span>. If the main verb uses<a class="conjugation_explanation_link_intext verb_link" href="/study/conjugations/ita/essere/" title="Click to see conjugations for essere" target="_blank">essere</a>
, <span style="font-style: italic;">potere</span> uses <span style="font-style: italic;">essere</span>.</p><div class="conjugation_explanation_title">1. With verbs using Avere</div>
<p>Most verbs, particularly transitive verbs like
<a class="conjugation_explanation_link_intext verb_link" href="/study/conjugations/ita/fare/" title="Click to see conjugations for fare" target="_blank">fare</a>
(<span style="font-style: italic;">to do</span>) or<a class="conjugation_explanation_link_intext verb_link" href="/study/conjugations/ita/parlare/" title="Click to see conjugations for parlare" target="_blank">parlare</a>
(<span style="font-style: italic;">to speak</span>), use <strong>avere</strong>. In these cases, <span style="font-style: italic;">potere</span> also uses <span style="font-style: italic;">avere</span>.</p><div class="conjugation_explanation_example_sentence">Noi non <strong>abbiamo potuto</strong> <span class="green_emphasis">fare</span> a meno di piangere. (<span style="font-style: italic;">We could not help but cry.</span>)</div>
<div class="conjugation_explanation_example_sentence_note">The verb <strong>fare</strong> uses <strong>avere</strong>, so <strong>potere</strong> uses <strong>avere</strong>.</div>
<div class="conjugation_explanation_example_sentence">Non <strong>ho potuto</strong> <span class="green_emphasis">parlare</span> con Marco. (<span style="font-style: italic;">I wasn't able to speak with Marco.</span>)</div>
<div class="conjugation_explanation_title">2. With verbs using Essere</div>
<p>Intransitive verbs indicating motion or change of state, such as
<a class="conjugation_explanation_link_intext verb_link" href="/study/conjugations/ita/andare/" title="Click to see conjugations for andare" target="_blank">andare</a>
(<span style="font-style: italic;">to go</span>) or<a class="conjugation_explanation_link_intext verb_link" href="/study/conjugations/ita/partire/" title="Click to see conjugations for partire" target="_blank">partire</a>
(<span style="font-style: italic;">to leave</span>), use <strong>essere</strong>. In this case, <span style="font-style: italic;">potere</span> also takes <span style="font-style: italic;">essere</span>, and the past participle must agree with the subject.</p><div class="conjugation_explanation_example_sentence">Non <strong>sono potuto</strong> <span class="green_emphasis">andare</span> al lavoro. (<span style="font-style: italic;">I couldn't go to work.</span>)</div>
<div class="conjugation_explanation_example_sentence_note">The verb <strong>andare</strong> uses <strong>essere</strong>, so <strong>potere</strong> uses <strong>essere</strong>.</div>
<div class="conjugation_explanation_example_sentence">Loro <strong>sono potuti</strong> <span class="green_emphasis">partire</span> presto. (<span style="font-style: italic;">They were able to leave early.</span>)</div>
<div class="conjugation_explanation_title">Reflexive Verbs</div>
<p>When <span style="font-style: italic;">potere</span> is used with a reflexive verb (like
<a class="conjugation_explanation_link_intext verb_link" href="/study/conjugations/ita/svegliarsi/" title="Click to see conjugations for svegliarsi" target="_blank">svegliarsi</a>
or<a class="conjugation_explanation_link_intext verb_link" href="/study/conjugations/ita/mettersi/" title="Click to see conjugations for mettersi" target="_blank">mettersi</a>
), the auxiliary depends on where you place the reflexive pronoun.</p><p><strong>1. Pronoun before the verb → Essere</strong></p>
<p>If the reflexive pronoun (mi, ti, si, ci, vi) is placed <strong>before</strong> the conjugated form of <span style="font-style: italic;">potere</span>, the entire construction behaves like a reflexive verb. Therefore, use <strong>essere</strong>.</p>
<div class="conjugation_explanation_example_sentence"><span class="green_emphasis">Si</span> <strong>sarebbero potuti</strong> <span class="green_emphasis">mettere</span> dei vestiti puliti. (<span style="font-style: italic;">They could have put on some clean clothes.</span>)</div>
<p><strong>2. Pronoun attached to the infinitive → Avere</strong></p>
<p>If the reflexive pronoun is attached to the <strong>end of the infinitive</strong>, the reflexive nature is contained within the infinitive. The modal verb <span style="font-style: italic;">potere</span> acts as a standard active verb and generally takes <strong>avere</strong>.</p>
<div class="conjugation_explanation_example_sentence"><strong>Avrebbero potuto</strong> <span class="green_emphasis">mettersi</span> dei vestiti puliti. (<span style="font-style: italic;">They could have put on some clean clothes.</span>)</div>
<div class="conjugation_explanation_title">Exceptions and Special Cases</div>
<p><strong>1. Used with Essere</strong></p>
<p>There is a notable exception: if the main verb following <span style="font-style: italic;">potere</span> is
<a class="conjugation_explanation_link_intext verb_link" href="/study/conjugations/ita/essere/" title="Click to see conjugations for essere" target="_blank">essere</a>
itself, the auxiliary must be <strong>avere</strong>, even though <span style="font-style: italic;">essere</span> normally takes <span style="font-style: italic;">essere</span>.</p><div class="conjugation_explanation_example_sentence">Tutto <strong>avrebbe potuto</strong> <span class="green_emphasis">essere</span> diverso. (<span style="font-style: italic;">Everything could have been different.</span>)</div>
<p><strong>2. Used Alone (Absolute Use)</strong></p>
<p>When <span style="font-style: italic;">potere</span> is not followed by another verb (often because the infinitive is implied), it always uses <strong>avere</strong>. This is common in phrases like "doing everything one could."</p>
<div class="conjugation_explanation_example_sentence">L'hanno presa in giro finché lei non ne <strong>ha potuto</strong> più. (<span style="font-style: italic;">They teased her until she could take no more.</span>)</div>
