On the other hand, the imperfect tense (el imperfecto) is used to describe past habitual actions or to talk about what someone was doing when they were interrupted by something else. In general, the imperfect is used to talk about past actions, conditions, or events that occurred regularly or frequently or that were in progress in a moment in the past. It is also used to tell time, talk about dates, give a person's age, and describe features, conditions, and feelings in the past. As in the preterite tense, there are two forms in this verbal tense, namely: <em>Regular Imperfect Forms</em> and <em>Irregular Imperfect Forms.</em>
The regular verb forms for both the preterite and the imperfect are given in three ways, that is, for <em>ar,</em> <em>er</em> and<em> ir</em> endings. So the conjugation will depend on the pronoun of the sentence and the verb ending. On the other hand, the irregular verb forms don't have a defined structure.
