By Michael McGettrickUpdated 12 October 2026

Quick check
Three quick questions on what you have just read. The full practice is further down.
Pick the right one
0/3Passé composé (a finished event) or imparfait (a habit, an action in progress or a description)?
Hier soir, je un film. (regarder: I watched)
Je un film tous les soirs. (regarder)
Quand je suis arrivé, Marie au téléphone. (parler: was talking)
The choice at a glance
Ask these questions about the verb, in order. The first yes decides. The colour marks the tense all page long.
| Test | Tense | Example |
|---|---|---|
| "used to" | imparfait | . - I used to play in the park. |
| "was ...-ing" | imparfait | . - He was reading. |
| a description | imparfait | . - It was cold. |
| it happened, done | . - He left. | |
| a counted length | . - I waited two hours. | |
| a sudden change | . - I got scared. |
The imparfait come first on purpose. English speakers reach for the by default, so the useful check is whether there is a reason not to.
To build the forms, see the passé composé guide and the imparfait guide.
Same verb, two tenses
One English past, two French ones. The column happened and is over; the imparfait column is a habit, a scene or an open stretch.

Words that point to each tense
Time phrases settle most choices. A point in time or a count takes the ; repetition or a long stretch takes the imparfait.

Watch . With a length it closes the action: . - I slept for two hours. With it opens a background: - while I was sleeping.
The interruption: je dormais quand...
The commonest way the two tenses meet: an action in progress (imparfait) is cut across by an event ( ).
je dormais (imparfait: going on)
le téléphone a sonné (passé composé: it happened)
Timeline from past to now, with now marked.
.- I was sleeping when the phone rang., .- When I arrived,was reading., .- While I was talking, he came in.
The order of the clauses can change; the tenses cannot. The action in progress keeps the imparfait wherever it sits.
Both tenses in one story
Read the story one sentence at a time. The imparfait paints the scene; each is a step forward.
| Step | French | Tense and why |
|---|---|---|
| 1 | . | imparfait: the time |
| 2 | . | imparfait: the weather |
| 3 | . | imparfait: in progress |
| 4 | . | : it happened |
| 5 | . | : next step |
| 6 | . | : next step |
| 7 | . | imparfait: description |
| 8 | . | imparfait: how he looked |
It was eight o'clock and it was cold. I was reading in my room. Someone knocked at the door. I got up. I opened the door. It was my brother. He looked tired.
When the story stops to describe, the tense goes back to the imparfait, as it does for the brother.
Verbs that change meaning
A few verbs say something different in each tense. The imparfait gives the state; the gives the moment it changed.
| Verb | Imparfait: state | P. composé: event |
|---|---|---|
- I knew | - I found out | |
- I knew | - I met | |
- I wanted | - I tried to | |
- I could | - I managed to | |
- I had | - I got | |
- I was supposed to | - I had to (and did) |
Marie.- I knew Marie (we were already acquainted).Marie 2010.- I met Marie in 2010.
Common mistakes English speakers make
| Wrong | Right | Why |
|---|---|---|
| | a counted event |
| | background state |
, | , | a sudden event |
| | a counted length is closed |
What to do next
- Retell yesterday in five sentences: two in the imparfait for the scene, three in the
for what happened. - Underline the time words first; they settle most choices.
- Add the third past tense with the plus-que-parfait.
