Common Mistakes
Mistake: Using the infinitive instead of the subjunctive.
Correct: Use 'no firmar' only in very specific contexts, but for direct negative commands, use 'no firmes' (tú) or 'no firme' (usted).
Why: The subjunctive is required for negative commands directed at a specific person.
Mistake: Confusing 'tú' and 'usted' forms.
Correct: Use 'no firmes' for 'tú' and 'no firme' for 'usted'.
Why: These are distinct commands and carry different levels of formality.
