Creer (to believe, to think) in the imperfect: 14 free exercises with an explanation after every answer, plus the full conjugation table.

IWhat to watch for

The imperfect of creer is regular — creía, creías, creía, creíamos, creíais, creían — with no spelling change, because the í of the ending is stressed and stays an í.

Creía is the natural way to describe what someone used to believe (de niño creía en los Reyes Magos) or a belief that turned out to be wrong: creía que eras mayor, I thought you were older. The preterite creí or creyó reports a single moment instead.
