Preterite vs. imperfect

Build the past world with the imperfect and move through its events with the preterite.

The short answer

Use the imperfect to present open background, description, habits, and actions viewed in progress. Use the preterite to present bounded events as complete. The same real-world action can use either tense when the storyteller changes viewpoint.

The useful model

Start with meaning, then choose the form.

The imperfect opens a window inside a past situation: the weather, the setting, a repeated habit, or an action already in progress. The preterite views an event from outside as a complete boundary and often changes that scene.

A strong story coordinates both layers. Describe what the world was like and what people were doing, then use the preterite for the arrival, discovery, decision, or other event that advances the narrative. Tense choice is a storytelling decision, not simply a property of the verb.

Decision routine

Work through the message in a dependable order.

Decide what role the verb plays

Separate scene, description, habit, and ongoing background from completed events on the main timeline.

Choose the viewpoint

Use the imperfect to stay inside an open past situation and the preterite to bound an event as a whole.

Coordinate the story

Let background create context, events create change, and pronouns keep known people and things connected across sentences.

Check the idea

Can you explain the decision?

You are describing rain already in progress when Ana arrived. Which tense frames the rain, and which advances the arrival?

Reveal the answer

Use imperfect for llovía and preterite for llegó.

The rain is open background; Ana’s arrival is the bounded event that changes the scene.
