How it's used

This expression is used to describe someone who has incomplete information or a superficial understanding of a situation. It often carries a slightly critical tone, implying that the person should not be acting like an expert or sharing information they do not fully grasp. It is a very common way to dismiss someone who is speculating based on rumors or partial facts.

Examples

gin2件si6事keoi5佢zi1知di1啲m4唔zi1知di1啲，m4唔hou2好man6問keoi5佢laa3喇。

He only knows bits and pieces about the matter, don't ask him.

nei5你hai6係mai6咪zi1知di1啲m4唔zi1知di1啲zau6就lyun6亂gam3咁gong2講aa4呀？

Are you just spreading rumors when you only know half the story?

Common phrases

Common mistake

Avoid using this to describe someone who is simply ignorant or knows nothing at all. It specifically refers to the state of having some, but not enough, information to form a complete picture.
