Past Subjunctive

In brief

The past subjunctive (congiuntivo passato) describes an action that is already complete from the viewpoint of a present opinion, doubt, hope, or feeling. It often follows che when the main clause expresses one of these attitudes toward what happened.

Form

Present subjunctive of avere or essere + past participle: abbia finito, sia arrivato. With essere, the participle agrees with the subject: sia arrivata, siano arrivati.

Usage

• Use it after a present-tense expression of doubt or opinion about a completed event.
• Use it after a present-tense expression of emotion or hope concerning something that has already happened.

Examples

• Penso che Marco abbia già finito il lavoro. — I think Marco has already finished the work.
• Non credo che abbiano visto il messaggio. — I don’t think they’ve seen the message.
• Sono contenta che Giulia sia arrivata in tempo. — I’m glad Giulia arrived on time.

Common mistake

❌ Non credo che hanno visto il messaggio.

✅ Non credo che abbiano visto il messaggio.

After non credo che, use the past subjunctive for an action that may already have happened, rather than the present perfect indicative.

Remember

The auxiliary is in the present subjunctive; the participle places the action before the present viewpoint.
