Passé Composé vs Imparfait
The passé composé describes a completed event that moves the story forward; the imparfait describes the background — what things were like, what used to happen, what was already going on. Both talk about the past, which is exactly why English speakers find the choice hard: English usually has just one simple past ("I ate", "it rained") where French forces you to pick.
The good news: the choice is not random, and it is not about how long ago something happened. It is about the role a verb plays in the story you are telling. Once you see that role, the right tense usually picks itself.
In short
- Passé composé = a snapshot: a completed event, something that happened. It moves the story forward.
- Imparfait = the film rolling in the background: descriptions, habits, and actions that were in progress. It sets the scene.

Think of a camera
Imagine you are filming the scene you are describing.
When the camera takes a snapshot — click, one finished event — that is the passé composé. The event has clear edges: it started, it ended, and the story has moved on.
When the camera just keeps rolling over the scene — the weather, people’s moods, what everyone was busy doing — that is the imparfait. Nothing is finished or starts; you are describing how things were.
Yesterday, I ate a crêpe at the market.
— One finished event with clear edges: snapshot, passé composé.
It was raining and the streets were empty.
— Pure scene-setting — nothing happens, so the camera keeps rolling.
Passé composé: the events of the story
Use the passé composé for the plot — the things that happened, one after another. If you could list them as bullet points of what occurred, they belong in the passé composé.
Use the passé composé for
- A completed action: it happened, it’s over
- A sequence of events: first this, then that
- A sudden change or interruption
- An action with a stated, finished duration ("pendant deux heures")
She closed the door and left.
— Two events in sequence — each one a snapshot.
Suddenly, everyone stood up.
— "Soudain" almost always announces a passé composé.
Imparfait: the background
Use the imparfait for everything that surrounds those events: descriptions, repeated habits, and actions that were already in progress when something else happened.
Use the imparfait for
- Descriptions in the past: weather, places, feelings, age
- Habits and repetition: "every Sunday", "used to"
- An action in progress that another event interrupts
- Background states: what you knew, wanted, could do
When I was little, I ate crêpes every Sunday.
— A repeated habit — English often says "used to".
Before, he could run ten kilometers.
— A lasting ability in the past, not a single event.
Using both in one sentence
This is where the system really shines. A very common French sentence shape is: imparfait for the action in progress, passé composé for the event that interrupts it. The camera is rolling — and then, click.
imparfait — background action + quand + passé composé — interrupting event
I was reading when the phone rang.
— Reading = in progress (film). The ring = one event (snapshot).
We were watching a movie when someone knocked at the door.
Signal words
Some time expressions strongly suggest one tense or the other. Treat them as hints, not laws — the story logic always wins.
| Points to passé composé | Points to imparfait |
|---|---|
| hier, ce matin-là | tous les jours, chaque été |
| soudain, tout à coup | d’habitude, souvent |
| une fois, deux fois | pendant que |
| puis, ensuite, après | quand j’étais petit(e) |
Verbs that change meaning
A handful of verbs shift meaning depending on the tense, because "state" and "event" versions of them mean different things in English too. These pairs are favorite exam questions — and they make great intuition tests.
| Verb | Imparfait (state) | Passé composé (event) |
|---|---|---|
| savoir | je savais — I knew | j’ai su — I found out |
| connaître | je connaissais — I knew (someone) | j’ai connu — I met |
| vouloir | je voulais — I wanted | j’ai voulu — I tried / decided to |
| pouvoir | je pouvais — I was able | j’ai pu — I managed to |
I knew the answer, but I only found out the result the next day.
— Knowing = ongoing state; finding out = one-moment event.
She wanted to leave, but she stayed.
— Imparfait "voulait" = the desire existed; nothing says she acted on it.
Common mistakes
✗Quand j’étais petit, j’ai joué au foot tous les jours.
✓Quand j’étais petit, je jouais au foot tous les jours.
A repeated habit ("tous les jours") takes the imparfait, even though each game was a finished event.
✗Je regardais la télé, puis je faisais mes devoirs.
✓J’ai regardé la télé, puis j’ai fait mes devoirs.
"Puis" signals a sequence of completed events — that’s plot, not background, so both verbs need the passé composé.
✗Il a dormi quand je suis arrivé.
✓Il dormait quand je suis arrivé.
The sleeping was already in progress when you arrived. The arrival is the snapshot; the sleeping is the film.
✗Hier, il a fait beau pendant que j’ai lu dans le parc.
✓Hier, il faisait beau pendant que je lisais dans le parc.
"Pendant que" introduces two ongoing, parallel backgrounds — both stay in the imparfait.

Frequently asked questions
Is the imparfait the same as the English past continuous ("was doing")?
It overlaps with "was doing", but it is broader. The imparfait also covers habits ("I used to play") and simple descriptions ("the house was old"), which English expresses with the plain past.
Can passé composé and imparfait appear in the same sentence?
Yes, constantly — it is one of the most common sentence shapes in spoken French. The imparfait describes what was going on, and the passé composé reports the event that happened: "Je dormais quand tu as appelé."
Do signal words like "soudain" or "souvent" always decide the tense?
No. They are reliable hints — "soudain" almost always goes with the passé composé, "tous les jours" with the imparfait — but the deciding factor is always whether the verb is a completed event or background.
Why does "je savais" mean something different from "j’ai su"?
A few verbs (savoir, connaître, vouloir, pouvoir) describe states in the imparfait and one-time events in the passé composé. "Je savais" means the knowledge was already there; "j’ai su" points to the moment you found out.
Memory tip
When you hesitate, ask: snapshot or film? If you could caption the verb "and then this happened", take the passé composé. If you would caption it "meanwhile, this is how things were", take the imparfait.
