How it's used
Functions primarily as a formal, written-style morpheme rather than a standalone verb in spoken Cantonese. It is almost exclusively encountered in compound words like 知悉 or 獲悉, typically within professional correspondence or news reports. Using it in casual conversation will sound overly stiff or pretentious.
Examples
I was already informed about this matter earlier.

Common mistake
Learners often mistakenly use it as a direct synonym for 知道 in daily speech, but it lacks the natural, conversational flow of the latter. It is better to stick to 知道 or 收到 for everyday communication.
