Definition

Do not; must not; used in signs, notices, and rules to express a command or prohibition.

How it's used

This character is strictly reserved for formal written notices, public signage, and official rules. It carries a sense of authority and distance that makes it sound unnatural in casual, face-to-face conversation. Using it in spoken Cantonese to tell a friend not to do something will sound like you are reading a legal document or acting like a stern official.

Common mistake

Learners often mistakenly use this in daily speech because they see it on signs. In everyday conversation, always use 唔好 instead of 勿 to express prohibition or advice.
