Imperfect Tense and Irregular Verbs

Irregular verbs follow the same imperfect formation rules as do regular verbs. Drop the -ons from the nous form and add the imperfect endings. Consider the following examples:

  • Tous les ans ils allaient à la plage. (They used to go to the beach every year.)

  • Je faisais mes devoirs. (I was doing my homework.)

The following is a list of the most common irregular present tense verbs whose imperfect forms follow the general rules:

  • aller (to go): nous allons

  • avoir (to have): nous avons

  • boire (to drink): nous buvons

  • conduire (to drive): nous conduisons

  • connaître (to know): nous connaissons

  • croire (to believe): nous croyons

  • devoir (to have to): nous devons

  • dire (to say, tell): nous disons

  • dormir (to sleep): nous dormons

  • écrire (to write): nous écrivons

  • faire (to make, do): nous faisons

  • lire (to read): nous lisons

  • mettre (to put): nous mettons

  • offrir (to offer): nous offrons

  • ouvrir (to open): nous ouvrons

  • pouvoir (to be able to): nous pouvons

  • prendre (to take): nous prenons

  • recevoir (to receive): nous recevons

  • savoir (to know): nous savons

  • venir (to come): nous venons

  • voir (to see): nous voyons

  • vouloir (to wish, want): nous voulons

Falloir (to be necessary) and pleuvoir (to rain) are used only in the third person singular form in the imperfect: il fallait (it was necessary) and il pleuvait (it was raining).

The only verb that does not follow the rule for the formation of the imperfect is être: j'étais; tu étais; il, elle, on était; nous étions; vous étiez; ils, elles étaient.
