Common Mistakes
Mistake: Using the imperfect 'instalaba' instead of the preterite 'instalé' for a single, completed action.
Correct: For a specific past action like 'I installed it yesterday', use 'instalé'.
Why: The preterite is for completed events, while the imperfect describes ongoing or habitual past actions.
Mistake: Forgetting the accent on 'instaló' (él/ella/usted) and 'instalé' (yo).
Correct: The forms are instaló and instalé, with accents on the final 'o' and 'é' respectively.
Why: These accents are crucial for distinguishing these preterite forms and indicating stress.
