Quick answer
Advertir carries a caution or corrective warning; avisar is the broader everyday verb for notifying.
A reliable test is to identify the job of the word before translating from English.
What each word does
advertir
to warn or admonish
Use advertir for calling attention to a risk, fault, or serious consequence.
avisar
to notify or let know
Use avisar for giving practical information or a warning in everyday language.
How to choose
- advertir: Choose advertir if the sentence points to calling attention to a risk, fault, or serious consequence.
- avisar: Choose avisar if the sentence points to giving practical information or a warning in everyday language.
Examples
O médico advertiu sobre os riscos do tratamento.
The doctor warned about the risks of the treatment.
Avise quando você chegar.
Let me know when you arrive.
Common trap
An aviso can be neutral. Advertir normally presupposes something the listener should avoid, correct, or take seriously.
Practice it in context
Pick one sentence from your real life and write it twice: once with advertir, then once with avisar. If both versions feel possible, name the meaning shift.
