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, but also to structures such as used to and would and even the past progressive. 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
