Conjugation of Irregular Verbs

Être and Avoir

Être (to be) and avoir (to have) are two of the most important verbs in French. They are used both as main verbs and as auxiliary verbs.

As main verbs, they are used to describe who you are, what you have, and many everyday situations. As auxiliary verbs, they are used to form compound tenses such as the passé composé.

In addition, être is used in many impersonal expressions.

Because être and avoir are irregular verbs and are among the most frequently used verbs in French, it is essential to learn their conjugations by heart.
