Compound tenses such as the passato prossimo are formed with the present indicative of the auxiliary verb avere or essere and the past participle (participio passato). The past participle of regular verbs is formed by dropping the infinitive ending -are, -ere, or -ire and adding the appropriate final ending: -ato, -uto, or -ito (see tables below).
