1. What Is the Past Subjunctive?

The past subjunctive (le subjonctif passé) is a verb tense in French used to express a completed action in situations where the subjunctive mood is required. It combines the idea of doubt, emotion, or necessity with the fact that the action has already happened. Think of it as the “finished version” of the present subjunctive.

For example, instead of saying “I’m glad you are here” (present), you would say “I’m glad you came” — the action of coming is now in the past.
