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 + imperfectpretérito.
  • Correct tense, wrong ending under speed (especially 3rd person).
