The core difference: snapshot vs background

The passé composé presents a completed event. The imparfait describes the background, habit, state or situation around that event.

J’ai vu un film. → I saw a film: one completed event.
Quand j’étais enfant, je regardais des films le dimanche. → I used to watch films on Sundays: a habit.
Il pleuvait quand je suis sorti. → It was raining when I went out: background plus event.

How to form each tense

The form matters, but the meaning matters more. Learn the structure, then practise choosing the right viewpoint.

Passé composé = auxiliary avoir or être + past participle.
Imparfait = nous present stem + endings: -ais, -ais, -ait, -ions, -iez, -aient.
Many movement/reflexive verbs use être in passé composé.
Descriptions, emotions, age, weather and repeated habits often use imparfait.

Time expressions that help you choose

Some phrases often point toward one tense, but do not treat them as automatic rules. Ask whether the action is a completed event or ongoing background.

Hier, soudain, puis, ensuite often support passé composé.
Tous les jours, souvent, quand j’étais petit often support imparfait.
Pendant que often introduces background with imparfait.
One sentence can use both tenses when an event interrupts a situation.

Practice with contrast pairs

Use pairs of sentences to train your ear and your instinct.

Je lisais quand tu as appelé. → I was reading when you called.
Nous habitions à Lyon, puis nous avons déménagé. → We lived in Lyon, then moved.
Elle était fatiguée, alors elle est rentrée. → She was tired, so she went home.

Imparfait vs Passé Composé: Practical Questions

When should I use passé composé instead of imparfait?

Use passé composé for a completed event, a sequence of finished actions, or a sudden change: what happened, what someone did, or what interrupted the background.

When should I use imparfait?

Use imparfait for background, description, age, weather, emotions, ongoing situations and repeated habits in the past: what was happening or what things were like.

Can passé composé and imparfait appear in the same sentence?

Yes. A very common pattern is background in imparfait plus event in passé composé, such as “Je lisais quand il a appelé.”

Are time expressions enough to choose the tense?

They help, but meaning matters more. “Souvent” often points to imparfait and “soudain” to passé composé, but always ask whether you mean habit/background or completed event.
