How it's used

Beyond the physical act of fastening, this verb is frequently used in financial contexts to mean deducting money from a balance or salary. It carries a sense of securing something in place, whether it is a physical buckle or a metaphorical hold on funds. When referring to clothing, it specifically targets the action of engaging buttons or hooks.

Examples

Have you buttoned up the buttons on your shirt yet?

Common mistake

Do not confuse this with the Mandarin usage where it can mean to frame or accuse someone, as that sense is not standard in Cantonese. Learners often use it incorrectly for tying knots, but for knots, use 綁 instead.
