Passé Composé in French: The Complete Beginner's Guide

Once you can handle the present tense, the next thing you'll want to say is what already happened — what you ate, where you went, who you saw. That's the job of the passé composé, French's most common past tense. It looks intimidating at first because it's built from two parts instead of one, but the logic is simple once you see the pattern. In this guide you'll learn how to build the passé composé with avoir and être, when to use each one, how past participles change to agree with the subject, and the mistakes that trip up almost every English speaker.

What the passé composé actually is

The passé composé is a compound tense: it's made of two pieces glued together.

1. A helping verb (avoir or être) conjugated in the present tense

2. The past participle of the main verb

So "I ate" becomes j'ai mangé — literally "I have eaten." English does something similar ("I have eaten"), which makes this tense far more intuitive for English speakers than it looks on paper. The hard part isn't the concept; it's knowing which helping verb to use and how to form the past participle.

Step 1: Form the past participle

For regular verbs, the past participle follows the infinitive ending:

So manger (to eat) becomes mangé, choisir (to choose) becomes choisi, and attendre (to wait) becomes attendu. Many common verbs are irregular here, though — avoir → eu, être → été, faire → fait, voir → vu. These irregular participles just have to be memorised, since there's no shortcut.

Step 2: Choose the right helping verb — avoir or être?

Here's the part that actually causes confusion. Most verbs use avoir. Only a small, specific list of verbs uses être instead — mostly verbs of movement or state change. A popular trick to remember them is the acronym DR & MRS VANDERTRAMP, where each letter is a verb that takes être:

Every other verb — manger, parler, finir, voir, faire — takes avoir. If you're not sure, default to avoir; it covers the large majority of verbs.

Passé composé with avoir

Take manger (to eat): conjugate avoir in the present, then add the past participle mangé, which stays the same for every subject.

Notice the participle mangé never changes — that's the key difference from être verbs, below.

Passé composé with être — and the agreement rule

Take aller (to go): conjugate être in the present, then add the past participle allé. But with être verbs, the participle must agree in gender and number with the subject, just like an adjective:

Add -e for feminine subjects, -s for plural subjects, -es for feminine plural. This is the single biggest source of passé composé mistakes for English speakers, since English past tense never changes based on gender.

The passé composé in real sentences

Making it negative

Wrap the helping verb — not the participle — in ne ... pas:

• Je n'ai pas mangé. (I didn't eat.)

• Elle n'est pas venue. (She didn't come.)

The participle (mangé, venue) always stays outside the ne ... pas, right after it.

Common mistakes English speakers make

• Using avoir for every verb. The DR & MRS VANDERTRAMP verbs need être, and forgetting the agreement that comes with it is the most common slip-up.

• Forgetting participle agreement with être. Elle est allé (wrong) should be elle est allée (right) — the extra -e matters, even though it's often silent in speech.

• Mixing up irregular participles. Avoir → eu, not avoir-é. Faire → fait, not fais. These have to be learned individually.

• Confusing passé composé with imperfect. The passé composé is for completed, one-time actions ("I ate breakfast"); ongoing or habitual past actions ("I used to eat breakfast every day") use the imparfait instead — a different tense worth learning next.

Quick practice

Answers: 1. ai mangé · 2. est allée · 3. avons fini · 4. sont partis · 5. as eu

Frequently Asked Questions

When do you use avoir vs être in the passé composé? Most verbs use avoir. A small set of movement and state-change verbs — often remembered with the acronym DR & MRS VANDERTRAMP (aller, venir, partir, sortir, arriver, entrer, rester, tomber, naître, mourir, and their compounds) — use être instead, and their past participles must agree with the subject.

How do you form the past participle in French? For regular verbs: -er verbs end in -é (parlé), -ir verbs end in -i (fini), and -re verbs end in -u (vendu). Many common verbs, like avoir (eu), être (été), and faire (fait), are irregular and must be memorised.

Does the past participle always change to match the subject? No — only with être verbs. With avoir verbs, the participle stays the same regardless of who's speaking. With être verbs, add -e for feminine, -s for plural, and -es for feminine plural.

What's the difference between passé composé and imparfait? Passé composé describes a completed, specific action in the past ("I went to the store"). Imparfait describes ongoing, habitual, or background actions ("I used to go to the store every week" or "It was raining"). Many sentences actually use both together.
