English mostly gets by with one simple past tense and leaves the rest to context. French makes you choose between two — passé composé and imparfait — every time. Getting this right is less about memorizing endings — you already practice those on the conjugator — and more about deciding what kind of past you're describing.
Passé composé is for a completed action — it started and it finished. Imparfait is for the backdrop — something that was ongoing, repeated, or just describing how things were.
One event, start to finish
Ongoing, repeated, or descriptive
Je dormais quand le téléphone a sonné.
I was sleeping when the phone rang.
The imparfait draws the wavy background line — sleep was already in progress. The passé composé is the single point that cuts across it: the moment the phone rang.
A handful of verbs are usually about mental or physical states rather than actions — so switching them to passé composé doesn't just change duration, it changes what happened.
| Verb | Imparfait | Passé composé |
|---|---|---|
| savoir | savaisknew (already had the info) | ai sufound out (the moment it landed) |
| connaître | connaissaisknew, was acquainted with | ai connumet for the first time |
| vouloir | voulaiswanted (an ongoing wish) | ai vouludecided to (and it took real effort) |
| pouvoir | pouvaiswas able to (in general) | ai pumanaged to (this one time) |
