The passato prossimo is the most commonly used past tense in Italian.

It is a compound tense consisting of two words:

  2. The verb’s past participle (participio passato).

The participio passato of regular verbs is conjugated as follows:

  • verbs ending in -are take -ato to form their past participle (example: the past participle of mangiare is mangiato)
  • verbs ending in -ere take -uto to form their past participle (example: the past participle of cadere is caduto)
  • verbs ending in -ire take -ito to form their past participle (example: the past participle of capire is capito)

The basic rules to form the past participle of regular verbs are fairly simple, but unfortunately, many frequently used verbs in Italian, especially those ending in -ere, have an irregular past participle, which therefore does not follow the patterns of the table above.

The same happens in English: regular verbs take -ed to form the past participle. For example, the past participle of the regular verb to walk is walked, but many verbs do not follow this rule and have irregular forms, such as eaten, thought, gone, done, etc.

The only way for learners to use irregular forms correctly it’s to memorize them through constant use. The more you encounter an irregular form, the more natural it will sound to you.
