Preterite vs. imperfect

Grade 9 · Spanish · Free lesson

¡Hola! Ready to master the Spanish past tense? Let's explore how to choose the right past tense for your stories!

In Spanish, we have two main ways to talk about the past. The preterite tense is for completed actions, while the imperfect tense is for ongoing or repeated actions.

to learn

Think of the preterite as a single point in time. We use it for actions that started and finished at a specific moment, like 'Yo corrí (I ran)'.

Yo corrí (I ran) One completed action!

Think of the imperfect as a wavy line with no clear start or end. We use it for ongoing habits, like 'Yo corría (I used to run)'.

Yo corría (I used to run) Habitual or ongoing action!

We often combine both tenses in one sentence. The imperfect sets the background scene, and the preterite interrupts it with a sudden action.

✏️ Worked example

Analyze this sentence and choose the correct past tense verbs: 'While I was reading (leer), the phone rang (sonar).'

  1. Analyze the first action: 'was reading' (leer). This is an ongoing background action with no clear start or end.
  2. Justify the first verb: Because it is ongoing, we must use the imperfect tense. 'Yo leía (I was reading)'.
  3. Analyze the second action: 'the phone rang' (sonar). This is a sudden, completed event that interrupts the reading.
  4. Justify the second verb: Because it is a sudden interruption, we must use the preterite tense. 'El teléfono sonó (the phone rang)'.
  5. Combine your evidence to build the final correct sentence: 'Mientras yo leía, el teléfono sonó.'
