Definition: The imperfect tense (l'imparfait) is used to describe actions that were ongoing or habitual in the past, setting a background scene, or describing mental states and physical sensations.
Formation: To form the imperfect in French, take the nous form of the present tense, drop the ons, and add the imperfect endings:
Endings:
je: -ais
tu: -ais
il/elle/on: -ait
nous: -ions
vous: -iez
ils/elles: -aient
Examples:
Habitual Actions: "Quand j'étais jeune, je jouais au football tous les weekends." (When I was young, I used to play soccer every weekend.)
Describing Background: "Il faisait beau et les oiseaux chantaient." (It was nice outside and the birds were singing.)
Mental States: "Elle avait peur de l'obscurité." (She was afraid of the dark.)
Common Time Expressions:
"tous les jours" (every day),
"souvent" (often),
"chaque été" (every summer)
Key Differences: Distinguish from the passé composé, which describes completed actions. Use l'imparfait for ongoing actions or background details while using passé composé for specific events.
