U+6263 "扣" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

扣

U+6263 "扣" CJK Unified Ideograph-# is a Chinese character that primarily conveys the meanings of to knock, to strike, to fasten, or to deduct, and it is commonly used in modern Chinese vocabulary. In practical terms, this character appears in words like "扣子" meaning a button, "扣除" meaning to deduct or subtract, and "扣留" meaning to detain or hold back, reflecting its semantic range from physical actions of joining or hitting to abstract concepts of withholding. The character is composed of the radical 扌 (shǒu, meaning hand) on the left, indicating manual action, and the phonetic component 口 (kǒu, meaning mouth) on the right, though its pronunciation has evolved from that component. As a standard element in the CJK Unified Ideographs block, "扣" is used across Chinese, Japanese, and Korean writing systems, where it retains similar but sometimes contextually varied functions, such as in Japanese where it can mean to strike or to ask.
