Common Mistakes
Mistake: Using the imperfect for a single, completed staining event.
Correct: For a specific completed action, use the preterite: 'Manchó la pared' (He stained the wall), not 'Manchaba la pared'.
Why: The imperfect is for ongoing/habitual past actions, while the preterite is for completed ones.
Mistake: Confusing imperfect and preterite when describing past events.
Correct: Remember: imperfect for descriptions and ongoing/habitual actions ('manchaba'), preterite for completed actions ('manchó').
Why: Distinguishing between ongoing/habitual and completed past actions is a key challenge.
