How it's used
Functions as a formal idiom that carries a sense of complete lack of awareness or information. While it is widely understood in speech, it often sounds slightly more serious or emphatic than using plain phrases like 咩都唔知. It is frequently used to describe a total absence of knowledge regarding a specific topic or situation.
Examples
I really know absolutely nothing about this matter.
Are you completely in the dark about this plan?
Common phrases
to know nothing about...
Common mistake
Avoid using this in very casual, lighthearted contexts, as it can sound overly dramatic or literary compared to everyday spoken alternatives. It is not a verb that takes objects directly in the same way as simple verbs, so it is almost always preceded by 對於 or 對.
