In English the past perfect tense (trapassato prossimo) is formed with the auxiliary "had" the past participle of the main verb. In Italian, the trapassato prossimo, a compound tense, is formed with the imperfetto of the auxiliary verb avere or essere and the past participle of the acting verb.

Here are a few examples of the trapassato prossimo:

Già erano partiti quando sono arrivato. (They had already left when I arrived.)

Avevo chiuso le finestre quando è cominciato a piovere. (I had shut the windows when it started to rain.)

La macchina sbandava perché aveva piovuto. (The car was sliding because it had rained.)
