Passé composé vs Imparfait

A Tale of Two Tenses


When talking about the past in French, there are two different tenses that work together: the passé composé and the imparfait. Although English has verb forms that appear to be exact equivalents for each of these, they don’t quite match up in the two languages, so this is an area of difficulty for French students. The trick is to understand when, why, and how to use each French tense.

Structurally speaking, the passé composé is exactly the same as the English present perfect:

J’ai mangé. = I have eaten.

Both languages have a subject pronoun, a conjugated helping verb, and a past participle. But the passé composé is also equivalent to two other English tenses.

1. Present perfect J’ai mangé. I’ve eaten.
2. Simple past J’ai mangé à 7h. I ate at 7am.
3. Emphatic past Oui, j’ai mangé. Yes, I did eat.

In a nutshell, the passé composé names something that happened, with a clear beginning and end.

In contrast, the imperfect describes something incomplete. It’s in the past, but has no clear beginning or end. It’s often equivalent to the English past progressive.

Je mangeais. = I was eating.

Any time you’d use the English past progressive, it’s a pretty safe bet to use the French imperfect. The problem is that some English verbs aren’t typically used in the past progressive.

  • Il faisait froid. = It was cold. Not "It was being cold."
  • J’avais un chien. = I had a dog. Not "I was having a dog."

The imperfect is descriptive: it expresses what was happening, what something was like, or how something felt.

Here are some practical examples to help you understand the difference.

Il a plu ce soir. = It rained this evening.
Il pleuvait à 16h. = It was raining at 4pm.

Nous avons marché devant le Louvre. = We walked in front of the Louvre.
Nous marchions sous la pluie. = We were walking in the rain.

J’ai coupé des oignons. = I cut some onions.
Je coupais des oignons quand …. = I was cutting onions when ….

In the last example, a verb in the passé composé is going to interrupt the verb in the imperfect, such as Je coupais des oignons quand il est arrivé. = I was cutting onions when he arrived. This is a very typical construction.

Il était dans l’eau quand il a vu une méduse. = He was in the water when he saw a jellyfish.

Nous étions à la plage quand j’ai pris cette photo. = We were at the beach when I took this picture.

    I am a French teacher and was wondering if I could put a link on my class blog to your passé composé vs. imparfait video? It’s a challenging concept for kids and I love the way you capture it so clearly. It could bring more traffic your way :).
