Common Mistakes
Mistake: Using 'penetró' (preterite) instead of 'penetraba' (imperfect) for a background action.
Correct: For actions that were ongoing or habitual in the past, use the imperfect 'penetraba'.
Why: The preterite is for single, completed events, while the imperfect describes the past scene or repeated actions.
Mistake: Forgetting the accent on 'penetró' (él/ella/usted).
Correct: The él/ella/usted form requires an accent: penetró.
Why: The accent distinguishes this form from the present indicative 'penetra' and indicates stress.
