How it's used

Cantonese speakers rarely use this character as a standalone verb for 'to be' in daily speech, preferring 係 instead. It is mostly preserved in formal idioms or compound words like 是非, which refers to gossip or disputes. Using it as a direct translation for 'correct' in casual conversation will sound unnatural or overly literary.

Common mistake

Learners often mistake this for the common copula 係. While they share a written origin, they are distinct in modern usage, and using 是 in place of 係 will make your speech sound like a textbook or a period drama.
