The passé composé is a tense used to express an action or a state that happened in the past. We call it “composé” because it’s composed of two parts: An auxiliary, either the auxiliary “être”
to be or the auxiliary “avoir”
to have and a past participle of a verb. In this part we will only tackle the passé composé of the verbs of the third group that require the auxiliary “avoir” .
The verbs of the third group are called irregular because they don’t follow a specific rule when they are conjugated. Because there are so many irregular verbs, we will classify them here according to the formation of their past participle. In this lesson, we will study the verbs of the third group ending in “oire”, “ire” and also verbs that don’t follow any specific pattern or rule.
