The Vietnamese word "cảnh cáo" is a verb that translates to "to warn" or "to give a strong warning" in English. It implies a serious notification about potential consequences if certain behaviors continue.
In more advanced contexts, "cảnh cáo" can also relate to official warnings given by authorities (like a school or workplace) when someone breaks rules or laws. It can indicate that further actions may be taken if the behavior continues.
While "cảnh cáo" primarily means "to warn," it carries a connotation of seriousness and potential punishment. In contrast, "cảnh báo" (which means "to alert") may not imply any severe consequences but simply inform someone about a situation.
