Passé Composé vs Imparfait: Think Photo vs Video
Passé composé is a photo - a completed action. Imparfait is a video - background or habit. The clearest explanation of French's trickiest tense pair.
Think photo vs video: passé composé captures a completed action, like a photo (j’ai mangé - I ate). Imparfait describes background, ongoing states or habits, like a video (je mangeais - I was eating / I used to eat). They combine naturally: j’étais dans le jardin quand le téléphone a sonné.

Side-by-side comparison table
| Passé composé | Imparfait | |
|---|---|---|
| Job | completed, punctual event | background, ongoing, habitual |
| Signal words | hier, soudain, un jour | tous les jours, quand j’étais petit, souvent |
| Example | j’ai mangé | je mangeais |
Passé composé: the photo (completed action)
Single, finished events with a clear start and end. Signal words: hier (yesterday), soudain (suddenly), un jour (one day), plusieurs fois (several times, with a specific count).
Imparfait: the video (background, ongoing, habitual)
Descriptions, ongoing states, habits, “used to.” Signal words: tous les jours (every day), quand j’étais petit (when I was little), souvent (often), autrefois (in the old days).
The classic combo: both in one sentence
J’étais dans le jardin quand le téléphone a sonné (I was in the garden when the phone rang) - imparfait sets the scene, passé composé interrupts it. More examples: Il pleuvait quand je suis sorti. (It was raining when I went out.) Nous regardions la télé quand elle est arrivée. (We were watching TV when she arrived.)
Common mistakes
Using passé composé for descriptions - il était grand, not “il a été grand,” for an ongoing physical description. Overusing imparfait for a single, completed event.
