Spanish Verbs: Preterite vs Imperfect

There are two past tenses in the Spanish language: preterite and imperfect. As both of these tenses refer to actions in the past, it can be difficult for new learners to know when to use the preterite tense versus when use the imperfect tense. Below we'll explore the rules that will help you determine which past tense to use and when to use it.


The preterite tense is used for past actions that have been entirely completed. These actions have specific beginning and end points. These actions may be single events, actions that occurred repeatedly but for a specific number of times, or actions that were part of a chain of events. Read, study, and listen to the following examples, then repeat each out loud.

He went to the market last night.
Él fue al mercado anoche.
I walked to the store, bought some food, and went to my sister's house.
Caminé a la tienda, compré comida, y fui a la casa de mi hermana.

cumplir años
to get married
to die
to graduate


The imperfect tense is used for past actions that do not have a definite end. These actions have not yet been completed or refer to actions that were repeated habitually. The imperfect tense is used for "setting the stage" for another action, for telling time, to describe people (characteristics) in the past, to communicate past physical or mental states, and for stating one's age. Read the following examples, then repeat each out loud.
