The imperfect tense in Spanish is a verb form used to express happenings and actions in the past that are viewed as incomplete, continuous, repeated, or habitual.
When using the imperfect, the action is considered ‘incomplete.’ It doesn’t have a definite beginning or end. Maybe the time frame is unknown or unimportant.
We can use the imperfect to provide contextual or background information for past actions. It gives us more detail about when the past action happened.
