How it's used
Emphasizes a strong warning or urgent advice, often functioning as a more intense version of 記得 or 唔好. It carries a sense of earnest concern, suggesting that the speaker has considered the potential negative consequences if the advice is ignored. It is almost exclusively used in imperative sentences to guide the listener's future actions.
Examples
You must be sure to watch for cars when crossing the road.
Whatever you do, don't tell him where we are going.

Common mistake
Learners often mistake it for a general adverb meaning 'definitely', but it is specifically reserved for instructions or warnings. You cannot use it to describe a past event, such as saying 'I definitely went there', which would require a different adverb like 一定.
