How it's used

非 is primarily used in formal, written, or literary contexts in Cantonese. It often appears in set idioms or formal expressions to add emphasis to a negation. In everyday spoken Cantonese, 唔係 or 唔係要 is almost always preferred over 非.

Examples

This matter is no small thing, you need to be careful.
He insists on going to buy clothes today, no matter how I try to persuade him.

Common mistake

Learners often try to use 非 as a direct replacement for 唔 in casual speech, which sounds unnatural or overly dramatic. It is not a general purpose negation particle.
