Introduction to auxiliary verbs in French
In French, an auxiliary verb (verbe auxiliaire) is a verb that is used alongside another verb to form compound tenses, passive voice constructions, and other complex verb forms. For example when you say I have eaten (J’ai mangé), ai (from avoir) is the auxiliary verb. The two main auxiliary verbs in French are “avoir” (to have) and “être” (to be).
Avoir (to have) as an auxiliary verb
- Usage: Avoir is the most commonly used auxiliary verb in French. It is used in compound tenses such as the passé composé to indicate actions that have occurred in the past.
- Example: J’ai mangé. (I have eaten.) – ai is the conjugated form of avoir in the passé composé, and mangé is the past participle of the main verb manger (to eat).
Être (to be) as an auxiliary verb
- Usage: Être is also used as an auxiliary verb in certain circumstances, particularly with a subset of verbs that express motion, change of state, or a reflexive action.
- Example: Elle est partie. (She has left.) – est is the conjugated form of être in the passé composé, and partie is the past participle of the main verb partir (to leave).
Other Auxiliary Verbs:
- Modal Verbs: Some modal verbs, such as devoir (must/have to), pouvoir (can/to be able to), and vouloir (want), can also function as auxiliary verbs in compound tenses.
- Passive Voice: In passive voice constructions, the past participle of the main verb is combined with être to form the passive voice. For example, _La porte est fermée. (The door is closed.)
