FAQ: Tense Comparisons Pairs
What is the difference between preterite and imperfect in Spanish?
The preterite describes completed actions with clear endpoints ("I ate lunch"), while the imperfect describes ongoing, habitual, or background actions ("I was eating lunch" or "I used to eat lunch"). Think of the preterite as a photograph capturing a specific moment, and the imperfect as a video showing continuous action.
When should I use the subjunctive instead of the indicative in Spanish?
Use the subjunctive for situations involving doubt, desire, emotion, recommendation, or unreality. The indicative states facts and certainties. A helpful trigger list includes verbs like "querer que," "esperar que," "dudar que," and expressions like "es posible que." If the action is uncertain or wished for, it likely needs the subjunctive.
