Common Mistakes

• Mistake: Using the imperfect ('penetraba') for a single, completed past action.

  Correct: For a specific, completed action in the past, use the preterite ('penetró').

  Why: The imperfect describes ongoing or habitual past actions, not punctual completed ones.

• Mistake: Confusing 'penetrabamos' (nosotros, imperfect) with 'penetramos' (nosotros, preterite/present).

  Correct: Ensure you use the '-aba' ending for the imperfect: 'penetrabamos'.

  Why: The '-aba' ending is crucial for the imperfect tense to distinguish it from the preterite and present.
