How it's used

Expresses strong disbelief or skepticism when an outcome contradicts expectations. It functions as a rhetorical device to challenge the validity of a situation rather than literally questioning the lack of a reason. Often paired with sentence-final particles like 㗎 or 嘛 to emphasize the speaker's incredulity.

Examples

He is usually so hardworking, it is impossible that he would fail.
That cannot be right, I clearly put it on the table.

Common phrases

That cannot be possible.

Common mistake

Do not use this to mean 'no reason' in a literal sense, such as 'I did it for no reason'. For that meaning, use 冇原因 or 無端端 instead.
