What is l’imparfait?
L’imparfait (the imperfect) is a French past tense. It describes states and actions that were ongoing or repeated in the past.
The imperfect can correspond to the English simple past tense (I did, I went …), but also to structures such as used to and would and even the past progressive (I was doing, I was going …).
L’imparfait is used to tell stories and report on past actions, mostly in written contexts. We conjugate the imperfect by adding the endings -ais, -ais, -ait, -ions, -iez and -aient to the root of the present tense nous form of the verb.

How to conjugate the imperfect tense in French
To conjugate the imperfect tense in French, we take the present-tense stem of the 1st person plural form of the verb (the nous form), and add the following endings (identical for verbs of all groups):
Person | er-verbs (nous aimons) |
ir-verbs (nous finissons)* |
ir-verbs (nous dormons)** |
re-verbs (nous vendons) |
---|---|---|---|---|
1st person singular (I) | j’aimais | je finissais | je dormais | je vendais |
2nd person singular (you) | tu aimais | tu finissais | tu dormais | tu vendais |
3rd person singular (he/she/it) | il/elle/on aimait | il/elle/on finissait | il/elle/on dormait | il/elle/on vendait |
1st person plural (we) | nous aimions | nous finissions | nous dormions | nous vendions |
2nd person plural (you) | vous aimiez | vous finissiez | vous dormiez | vous vendiez |
3rd person plural (they) | ils/elles aimaient | ils/elles finissaient | ils/elles dormaient | ils/elles vendaient |
* Most ir-verbs are conjugated like finir. Choisir, réagir, réfléchir and réussir belong to this group. Here we add an -iss- to the word stem in the plural forms.
** The ir-verbs that are not conjugated like finir, are conjugated like dormir. Mentir, partir and sentir are part of this group. We do not add -iss- to form the plural.
The verb avoir is regular in the imperfect; only être has an irregular conjugation in this tense.
Person | avoir | être |
---|---|---|
1st person singular (I) | j’avais | j’étais |
2nd person singular (you) | tu avais | tu étais |
3rd person singular (he/she/it) | il/elle/on avait | il/elle/on était |
1st person plural (we) | nous avions | nous étions |
2nd person plural (you) | vous aviez | vous étiez |
3rd person plural (they) | ils/elles avaient | ils/elles étaient |

Exceptions to the conjugation rules
- For verbs that end in -cer, the present form in the 1st person plural is constructed with ç (in order to preserve the soft c sound). This ç remains unchanged in the imparfait (except in the 1st and 2nd person plural forms).
- Example:
- lancer - nous lançons
je lançais, tu lançais, il lançait, nous lancions, vous lanciez, ils lançaient
- For verbs that end in -ger, the present form in the 1st person plural is constructed with e (in order to preserve the soft g sound). This e remains unchanged in the imparfait (except in the 1st and 2nd person plural forms).
- Example:
- manger – nous mangeons
je mangeais, tu mangeais, il mangeait, nous mangions, vous mangiez, ils mangeaient
- The verbs falloir and pleuvoir, which are only used in the 3rd person singular, are conjugated as follows in the imparfait:
- Example:
- falloir → il fallait
pleuvoir → il pleuvait
