Common Mistakes
Mistake: Using the infinitive with 'no' for negative commands.
Correct: For negative commands, use the present subjunctive form preceded by 'no', e.g., 'no observes'.
Why: The infinitive is used for positive commands with 'nosotros' and 'vosotros' (e.g., '¡Vamos a observar!'), but negative commands always require the subjunctive.
Mistake: Confusing the negative imperative with the simple present.
Correct: Remember that negative commands use the subjunctive mood, not the indicative. 'No observas' is a statement, while 'no observes' is a command.
Why: The subjunctive mood is essential for expressing commands, wishes, and doubts.
