Common Mistakes

  • Mistake: Using 'transformamos' (preterite) when referring to a habitual past action.

    Correct: For past habits, use the imperfect: 'transformábamos'. 'Transformamos' implies a specific, completed instance.

    Why: The preterite marks completed actions, while the imperfect describes ongoing or habitual past actions.

  • Mistake: Forgetting the accent on the 'yo' form.

    Correct: The correct form is 'transformé' with an accent on the 'é'.

    Why: The accent on the final vowel distinguishes the preterite 'yo' form from the present tense and indicates the stress.
