French conjugation in past subjunctive


The past subjonctive or passé du subjonctif in french, is a compound tense, which means it has two parts:
  • the auxiliary verb in present subjonctive (either avoir or être)
  • the past participle of the main verb

Grammatical agreement

Like all French compound conjugations, the past subjonctive may be subject to grammatical agreement:
  • When the auxiliary verb is être, the past participle must agree with the subject, except for reflexive verbs (same rules as conjugation with auxiliary avoir) and invariable past participles.
  • When the auxiliary verb is avoir, the past participle must agree with its direct object when the direct object is placed before the verb.
