U+82A5 "芥" CJK Unified Ideograph-# Unicode Character
U+82A5 "芥" CJK Unified Ideograph-# is a Chinese character (hanzi) that represents a type of mustard plant, specifically referring to the species Brassica juncea, and by extension its seeds which are used to produce mustard condiment. In classical and modern Chinese, it also carries the metaphorical meaning of something trivial or insignificant, as seen in the common compound "芥蒂" (jiè dì), which describes a minor grievance or petty dissatisfaction. The character is composed of the "grass" radical (艹) on top, indicating its botanical nature, and the phonetic component "介" (jiè) below, which provides a clue to its pronunciation. It appears frequently in both literary and culinary contexts across East Asian languages that use Chinese characters, including Japanese and Korean.
