Auxiliary verbs – what are they?

Auxiliary verbs are most commonly used when forming the perfect and pluperfect in French and they come from avoir and être. They are called auxiliaries because they support the main verb you want to write in a past tense.

You will either use them in their present or imperfect tense form, and add on a past participle.
