Preterite vs Imperfect: Part III

Notes:

  1. The written lesson is below.
  2. Links to quizzes, tests, etc. are to the left.

 

You have already learned that the preterite and the imperfect are used in different situations. The preterite is used for actions that are viewed as completed, while the imperfect is used for actions that did not have a definite beginning or a definite end.

Estudié dos horas.

I studied two hours.
(completed action)

Yo estudiaba antes de los exámenes.

(no definite beginning or end)

Some verbs actually change meaning, depending upon whether they are used in the preterite or the imperfect. This is not surprising, since the difference in meaning can be traced back to the different way in which these two past tenses are used.
