How it's used

While often used in formal warnings or signs, in spoken Cantonese it carries a slightly more serious or cautionary tone than the more common 小心. It is frequently used when advising someone to be alert to a specific, potentially dangerous situation rather than just general caution. You will often hear it paired with 啲 to soften the command, making it sound more like friendly advice than a stern order.

Examples

Be careful of cars when crossing the road.
Watch your step while walking, the ground is very slippery.

Common phrases

be a bit more careful
take care of your health

Common mistake

Learners often confuse this with 小心, but 小心 is much more versatile and used in almost every daily situation. Using 當心 in casual, low-stakes contexts can sound slightly stiff or overly dramatic.
