Imperfect vs Preterite Practice
DELE speaking and writing punish “almost-right” storytelling: you chose the wrong past tense, then everything downstream gets messy.
This drill trains the real skill: picking the tense quickly and producing the form without hesitation.
Use it when you’re confident on rules but still freeze mid-sentence deciding between background (imperfect) and completed events (preterite).
DELE outcomes
- Choose tense faster with time cues (siempre, de repente, mientras, ayer).
- Tell cleaner past narratives with fewer self-corrections.
- Improve writing accuracy on narration tasks (letters, stories, opinions).
Common mistakes to fix
- Using preterite for a habitual background (“Siempre fui…”).
- Using imperfect for a completed event (“Ayer iba al banco…”).
- Missing the “interrupt” pattern: Estaba + imperfect → pretérito.
- Correct tense, wrong ending under speed (especially 3rd person).
