How it's used
Functions as a formal nominalizer that turns a preceding verb phrase into a noun phrase, effectively acting as a formal way to say "the matter of" or "the issue of". It is almost exclusively used in formal writing, business correspondence, or serious public announcements. Using it in casual, everyday speech will make you sound overly stiff or like you are reading from a legal document.
Examples
Have you thought clearly about the matter of moving house?
They have strong opinions regarding the matter of a salary increase.

Common mistake
Learners often overuse it in daily conversation where a simple 嘅事 or just the verb phrase itself would be more natural. It is not a generic suffix for all nouns, but specifically for framing an event or action as a topic of discussion.
