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 Sentence | Meaning | Pronunciation |
|---|---|---|
| J’ai parlé. | I spoke | zhay par-lay |
| Elle est venue. | She came | el ay vuh-ny |
The first uses avoir.
The second uses être.
