The passé composé with avoir.

Passé composé with avoir: the core idea

To talk about a finished past action, French often uses:

• avoir (present) + past participle

Step-by-step: how to build the sentence

1. Choose the right form of avoir (ai / as / a / avons / avez / ont).

2. Add the past participle of the main verb (ex. joué, perdu, marqué).

3. Keep the usual word order: Subject + avoir + past participle.

Past participle: common patterns (quick recognition)

You often recognize the past participle like this:

Important: some verbs are irregular (ex. perdre → perdu, courir → couru), so it’s normal to learn them one by one.

Agreement: when does the past participle change?

• With avoir, the past participle is usually invariable (no extra letters).

• It changes only if the direct object (COD) is placed before the verb.

Agreement endings (when needed):

• feminine: + e (mangé → mangée)
• masculine plural: + s (mangé → mangés)
• feminine plural: + es (mangé → mangées)

A1 tip: if this feels complex, focus first on the main structure avoir + past participle. You can add agreement later when you meet it (often with que or pronouns like la, les).

Negation and questions (very common in conversation)

• Negation: ne + avoir + pas + past participle

  Je n’ai pas gagné. / Nous n’avons pas couru.

• Simple question (spoken): Est-ce que + subject + avoir + past participle

  Est-ce que tu as perdu ?

Self-check: choose the right helper fast

• Ask: Who did it? → that decides ai / as / a / avons / avez / ont.

• Ask: What action is completed? → that decides the past participle.

• Quick warning sign for agreement: do you see a direct object before the verb (often with que, le/la/les)? If not, don’t change the participle.

Common mistakes to avoid

• Don’t mix up the forms of avoir:

  Nous a couru → Nous avons couru

• Don’t add agreement automatically with avoir:

  Elles ont mangées une pomme → Elles ont mangé une pomme

• Watch elision with je:

  Je ai → J’ai
