Preterite vs. Imperfect: The Big Choice
The defining A2 challenge: preterite = completed event, imperfect = background/habit/state. 10 contrast pairs with analysis.
A lesson of Spanish A2 — Elementary, in Reflexive Verbs, about 10 minutes.
By the end of this lesson, you will be able to choose correctly between the preterite and the imperfect by applying a clear decision framework and recognizing the contrast in paired sentences.
The Core Rule
| Tense | Ask yourself | Signal words |
|---|---|---|
| Preterite | Did this action start and finish? Is it a single event? | ayer, una vez, de repente, el lunes pasado |
| Imperfect | Was this ongoing, habitual, or a background state? | siempre, a veces, todos los días, cuando era niño |
A useful mental image: the imperfect is the stage set (what was already there) and the preterite is the actors' entrance (what happened on that stage).
