Day 44 — Être and Avoir in Passé Composé

1. Topic Introduction

In French, passé composé is built with an auxiliary verb plus a past participle. The two auxiliary verbs are:

Thank you for reading this post, don't forget to subscribe!
  • avoir (to have)
  • être (to be)

Every verb in passé composé must choose one of these two auxiliaries.

This means:

  • many verbs use avoir
  • some verbs use être

Understanding this choice is extremely important because it controls:

  • sentence construction
  • agreement rules
  • negatives
  • questions
  • pronunciation

Examples:

French SentenceMeaningPronunciation
J’ai parlé.I spokezhay par-lay
Elle est venue.She cameel ay vuh-ny

The first uses avoir.

The second uses être.
