Past gerund (avendo…, essendo…)

Forming the Past Gerund

The past gerund (gerundio passato) means "having done" or "having been." It is formed with two parts:

  • The present gerund of the auxiliary (avendo or essendo)
  • The past participle of the main verb (e.g., finito, analizzato)

Choose the auxiliary exactly as you would for the passato prossimo. Most verbs take avendo, but verbs of movement, states of being, and reflexives take essendo.

As always, when using essendo, the past participle must agree in gender and number with the subject.

Avendo analizzato l'invenzione, l'ingegnere l'ha capita facilmente.
Having finished the calculation, the scientist explained the theory.

Expressing Sequence and Cause

The past gerund shows that an action was completed before the action in the main clause. Because it sets up the background, it often implies a cause-and-effect relationship, translating to "since" or "because [subject] had..."

As with the present gerund, the subject of the past gerund must match the subject of the main verb.
