The past infinitive is a compound verb form, which means its conjugation has two components:
verb | conjugation | |
1. | auxiliary (avoir or être) | infinitive |
2. | main verb | past participle |
Par exemple…
Avoir verb: donner (to give)
avoir donné |
Être verb: sortir (to go out)
être sorti(e)(s) |
Pronominal verb: s’habiller (to get dressed)
s’être habillé(e)(s) |
Since the auxiliary verb stays in the infinitive, the conjugation for avoir verbs is the same for all subject pronouns.
Par exemple…
Après avoir donné du sang, je suis parti. | After having given blood, I left.![]() |
|
Après avoir donné du sang, nous sommes partis. | After having given blood, we left.![]() |
However, in the case of être and pronominal verbs, agreement of the past participle is required, and the reflexive pronoun must agree with the implied subject.
Par exemple…
Après être partie, elle a attrapé le bus. | After having left, she caught the bus.![]() |
|
Il faut nous être levés avant midi. | We have to have gotten up by noon.![]() |
Past participle agreement
As in all compound conjugations, the past participle in the past infinitive may need to agree in gender and number with the word it modifies – learn more.
