Common Mistakes
Mistake: Using 'estar + gerund' for habitual actions.
Correct: Say 'Yo alerto' (I alert) for habits, not 'Yo estoy alertando' (I am alerting) unless it's happening right now.
Why: The simple present is used for habitual actions, while 'estar + gerund' emphasizes an action in progress.
Mistake: Confusing 'alerta' (he/she alerts) with 'alerta' (alert!).
Correct: The context usually makes it clear, but remember 'Él alerta' is a statement, while '¡Alerta!' is a command.
Why: The same form can be a present indicative conjugation or an imperative command.
