How it's used

This character is almost exclusively used as a bound morpheme in formal compounds like 告誡 or 戒條. It carries a sense of serious, moral, or authoritative advice that goes beyond a casual reminder. You will rarely hear it used as a standalone verb in spoken Cantonese, where people would prefer 警告 or 提點 instead.

Examples

His father warned him not to spend money recklessly again.

Common mistake

Learners often mistake this for 戒, which means to abstain from something like smoking or drinking. While they share a similar visual component, 誡 is about verbal warnings or rules, whereas 戒 is about personal discipline and self-restraint.
