U+78AC "碬" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
碬
U+78AC "碬" CJK Unified Ideograph-# is a Chinese character used primarily in classical and historical texts, representing a type of whetstone or sharpening stone, often associated with the act of grinding or honing tools. It belongs to the Kangxi radical 112 (石, meaning "stone") and carries the phonetic component "叚" (jiǎ), indicating its sound while contributing to its meaning of a stone used for abrasion. In modern usage, this character is quite rare, appearing mostly in literary or specialized contexts rather than everyday communication, and it is not included in standard simplified Chinese character sets, remaining more common in traditional and premodern vocabulary.
