Common Mistakes

• Mistake: Using the preterite instead of the imperfect for ongoing past actions, e.g., 'Ayer fundamentó su teoría' (implying a single completed act) vs. 'Antes fundamentaba su teoría' (describing a past habit).

  Correct: Use the imperfect ('fundamentaba') for descriptions or habits in the past, and the preterite ('fundamentó') for completed actions.

  Why: The imperfect describes the setting or ongoing nature, while the preterite marks a specific, finished event.

• Mistake: Confusing the nosotros and vosotros forms, e.g., 'fundamentabais' for 'nosotros'.

  Correct: The correct forms are 'fundamentábamos' (nosotros) and 'fundamentabais' (vosotros).

  Why: These endings are distinct and indicate different grammatical persons.
