4. Avoir and Être in Compound Tenses

Compound tenses, such as the passé composé, are formed using an auxiliary verb (avoir or être) combined with the past participle of the main verb. The choice of auxiliary verb depends on the main verb being used.

Verbs that Use Avoir as an Auxiliary Verb

Most verbs in French use avoir as their auxiliary verb in compound tenses. For example:

• J’ai mangé (I ate)
• Nous avons fini (We finished)

Verbs that Use Être as an Auxiliary Verb

A small group of verbs, known as Dr. & Mrs. Vandertramp verbs, use être as their auxiliary verb in compound tenses. These verbs are often used to express motion or change of state. For example:

• Je suis arrivé(e) (I arrived)
• Elles sont parties (They left)

Note that when using être as an auxiliary verb, the past participle must agree in gender and number with the subject. For example:

• Elle est allée (She went)
• Ils sont allés (They went)

Some expressions in English use “to be” or “to have,” but their French equivalents use the other verb. For example:
