Common Mistakes
Mistake: Using the imperfect instead of the preterite for a single completed action.
Correct: For sewing one specific item, use 'cosí' (preterite), not 'cosía' (imperfect).
Why: The preterite marks a finished action, while the imperfect describes ongoing or habitual past actions.
Mistake: Forgetting the accent on 'cosió' and 'cosí'.
Correct: The forms are 'cosió' and 'cosí', with accents on the 'o' and 'i' respectively.
Why: The accent marks the stressed syllable and distinguishes these forms.
