Common Mistakes
Mistake: Forgetting the accent on the 'yo' form.
Correct: The 'yo' form is 'infiltré', not 'infiltre'.
Why: The accent mark is crucial to indicate the stress on the final syllable and distinguish it from other forms like the present subjunctive.
Mistake: Using the imperfect tense instead of the preterite for a single, completed action.
Correct: Say 'Me infiltraba en la fiesta' is usually wrong if it was a one-time event. Use 'Me infiltré'.
Why: The preterite marks a specific, completed action, while the imperfect describes ongoing or habitual past actions.
