Frequently Asked Questions
Can 'avisar' ever be used for something negative?
Yes, but it's about the act of informing, not the act of warning. You can say 'Me avisaron de su muerte' (They informed me of his death). The focus is on the transmission of information, even if the news itself is bad. 'Advertir' would imply you were being warned of a danger related to the death, which doesn't make sense.
What's the difference between 'una advertencia' and 'un aviso'?
They are the noun forms and follow the exact same logic! 'Una advertencia' is a warning (e.g., 'una advertencia de tornado' is a tornado warning). 'Un aviso' is a notice, announcement, or ad (e.g., 'un aviso clasificado' is a classified ad).
