Passé Composé vs Imparfait — Choosing the Right Tense

Why this matters

This is the lesson most French learners find hardest — and most satisfying to crack. The choice between passé composé and imparfait isn't random. There's a clear logic, and once you see it, you'll be able to tell stories in French with real nuance. This is what separates A2 learners from B1 speakers.

🦝 Remy says: "Imagine you're making a movie. The imparfait is the continuous background footage — the scenery, the atmosphere. The passé composé is each scene's key action — the moments that move the story forward. You need both to make a good film!"

The Core Rule

| Tense | Use it for... | Signal words | |

-|

--|

-| | Passé composé | Completed actions, specific events, what happened | soudain, puis, ensuite, un jour, hier | | Imparfait | Background, ongoing actions, states, habits | quand, pendant que, chaque jour, autrefois, toujours |

Side by Side

| Passé composé | Imparfait | |

|

--| | J'ai mangé une pizza. (I ate a pizza — done.) | Je mangeais quand il a appelé. (I was eating when he called.) | | Elle est arrivée à 8h. (She arrived at 8 — event.) | Elle arrivait toujours en retard. (She always arrived late — habit.) | | Il a plu hier. (It rained yesterday — fact.) | Il pleuvait quand je suis sorti. (It was raining when I went out — background.) |

Classic Pattern: Interruption

One of the most common patterns in storytelling:

Imparfait (ongoing) + quand + Passé composé (interruption)

• Je dormais quand le téléphone a sonné. = I was sleeping when the phone rang.
• Elle lisait quand il est entré. = She was reading when he came in.
• Nous regardions la télé quand la lumière est tombée. = We were watching TV when the power went out.

🦝 Remy's memory trick: "The imparfait is a river flowing calmly along. The passé composé is a stone thrown into it — it creates a moment, a splash, an event. River + stone = good storytelling."
