- L'Imparfait (Imperfect)
The imperfect is used for: (1) An action that was going on in the past at the same time as another action. (2) An action that was going on in the past when another action occurred. (3) An action that a person did habitually in the past. (4) A description of a mental or physical condition in the past. (5) An action or state of being that occurred in the past and lasted for a certain length of time prior to another past action. In English, it is usually translated as a pluperfect tense ("had been", etc) and is formed with "had been" plus the present participle of the verb you are using. It is like the special use of the present tense, except that the action on state of being no longer exist in the present.
It is created using special endings attached to the stem verb.
