礱
U+7931 "礱" CJK Unified Ideograph-# is a traditional Chinese character that primarily means "to grind" or "to sharpen," often referring to the action of using a millstone or whetstone. It is composed of the radical 石 (stone) combined with a phonetic component, and it appears in classical texts and some modern terms related to milling, grinding tools, or the process of smoothing surfaces.
