For regular -er verbs:

Take the infinitive form (e.g., parler, finir, rendre) Remove the -er ending Add the imparfait endings: -ais, -ais, -ait, -ions, -iez, -aient 

For regular -ir verbs

Take the infinitive form (e.g., choisir, grandir, finir) Remove the -ir ending Add the imparfait endings: -issais, -issais, -issait, -issions, -issiez, -issaient 

For regular -re verbs

Take the infinitive form (e.g., vendre, attendre, entendre) Remove the -re ending Add the imparfait endings: -ais, -ais, -ait, -ions, -iez, -aient

Common Everyday Usage Patterns

Description of Past Habits

Background Information

It’s used to provide background information or set the stage for a main event in the past. For instance: “Il faisait beau ce jour-là.” (The weather was nice that day.) 

Mental and Emotional States

Points to Note About the Imparfait Tense

Passé Composé vs. Imparfait

The imparfait and passé composé (a compound past tense) are often used together to express the completion of an action in the past (passé composé) and provide context or background (imparfait). For example: “Il regardait la télévision quand son ami est arrivé.” (He was watching TV when his friend arrived.) 

Conditional

The imparfait is used as the base for forming the conditional mood in French. For instance, “Je mangerais” (I would eat) is formed from “je mangeais” (I was eating). 

Si Clauses

In hypothetical or “if” clauses (si clauses), the imparfait is often used to express a condition in the past. For example: “Si j’avais de l’argent, j’achèterais une nouvelle voiture.” (If I had money, I would buy a new car.) 

Narration

In storytelling or writing, the imparfait is frequently used to set the scene and describe ongoing actions while the passé composé is used for specific events or actions that interrupted the ongoing ones.
