Common Mistakes
Mistake: Using the imperfect for a single, completed tuning action.
Correct: For a specific, finished act of tuning, use the preterite: 'Afiné la trompeta' (I tuned the trumpet), not 'Afinaba la trompeta'.
Why: The preterite marks completed actions, while the imperfect describes ongoing or habitual past actions.
Mistake: Confusing the yo and él/ella/usted forms.
Correct: Both 'yo afinaba' and 'él/ella/usted afinaba' use the same form. Context is key.
Why: This is a feature of the imperfect tense for -ar verbs; the subject pronoun clarifies who is performing the action.
