Preterite vs imperfect in Spanish: when to use each

preterite vs imperfect Spanish

What is the difference between preterite and imperfect?

The preterite, also called pretérito indefinido or pretérito perfecto simple, presents an event as a complete unit: Llegué, vi el mensaje y llamé. It can describe a brief event or a long but bounded period, so duration alone does not decide the tense.

The imperfect opens a view inside a past situation: Vivía allí, llovía, eran las ocho. It commonly describes habits, ongoing background, age, time, weather and states without presenting their endpoints.

Time expressions are clues, not switches. Siempre can appear with a bounded summary, and durante tres años can take either viewpoint. Ask whether you are reporting the event as a whole or looking inside the situation.

Choose in four questions

Is the event counted, completed, begun, ended or treated as one bounded whole? Choose the preterite.

Is it a habit, description, state or action in progress with no endpoint in focus? Choose the imperfect.

Does one event interrupt or enter an ongoing scene? Put the background in the imperfect and the event in the preterite.

Could both be grammatical? Decide whether the speaker means a completed result or an ongoing state; the tense changes the viewpoint and sometimes the English translation.

32 preterite vs imperfect examples

The table moves from clear completed events and background uses to mixed narration and verbs whose meaning shifts with viewpoint.

Four decisions that cover most cases

First separate bounded events from background; then practise both together and compare meaning-changing pairs.

Do signal words decide the tense?

Words such as ayer, una vez and de repente often accompany the preterite; siempre, de niño and mientras often accompany the imperfect. They are useful evidence, but the intended viewpoint remains decisive.

Compare Viví allí tres años, which packages the period as complete, with Vivía allí cuando nos conocimos, which supplies background. A long action can be preterite; a short state can be imperfect.

In narration, the imperfect acts like the open scene and the preterite like a marked event. This is a meaning contrast, not a rule that one tense is simply “long” and the other “short”.
