Common Mistakes
Mistake: Using the infinitive with 'no'.
Correct: Use 'no' followed by the present subjunctive form, e.g., 'no alternes'.
Why: Spanish negative commands require the subjunctive mood, not the infinitive.
Mistake: Confusing negative imperative with other negative constructions.
Correct: Remember that negative commands are direct orders not to do something, using the subjunctive.
Why: It's easy to mix up direct negative commands with general statements about not doing something in other tenses.
