Conjugation of irregular verbs: While the majority of Italian verbs are regular, many of the most commonly used ones are irregular; they do not follow the regular pattern of conjugation (infinitive stem + endings). In particular, the auxiliary verbs essere and avere, and the common modal verbs potere (ability, to be able to), dovere (duty, to have to), stare (to stand, to be in a particular state), sapere (to know), and volere (to want to) are all irregular.
