Irregular Past Participles

Many of the most frequently used Italian verbs have irregular past participles — forms that do not follow the standard -ato, -uto, or -ito patterns. Since these verbs appear in everyday conversation, mastering their participles is essential for fluent use of the passato prossimo.

Why Are Some Participles Irregular?

Italian irregular past participles are mostly inherited from Latin. They tend to be shorter than what you would expect from the regular pattern. For example, scrivere (to write) would regularly produce scrivuto, but the actual past participle is scritto. These forms must simply be memorised, but patterns exist that make the task easier.
