The passé composé is a French verb tense used to talk about actions completed in the past. It is formed using an auxiliary verb (avoir or être) plus a past participle. For regular verbs, the past participle ends in é, i, or u depending on the verb conjugation. Irregular verbs have unpredictable past participle forms that must be memorized. When used with a direct object pronoun, the pronoun comes before the auxiliary verb and the past participle agrees in gender and number with the pronoun. Examples are provided of forming and using the passé composé.
