Common Mistakes
Mistake: Using the infinitive with 'no'.
Correct: Say 'No acelerar' is incorrect; use 'No aceleres' (tú) or other subjunctive forms.
Why: Spanish commands, positive or negative, require conjugated verb forms, not the infinitive.
Mistake: Confusing 'no' with 'nunca'.
Correct: Use 'no aceleres' for 'don't speed up' and 'nunca aceleres' for 'never speed up'.
Why: 'No' negates a specific instance, while 'nunca' implies a general prohibition.
