About
The character 疖 is a phono-semantic compound, with the sickness radical 疒 providing the semantic category of skin or bodily ailments. The internal component 卩 serves as the phonetic element, replacing the more complex phonetic component 節 used in the traditional form 癤. Etymologically, the character specifically denotes a boil or furuncle, a localized skin infection caused by bacteria in a hair follicle. Its meaning has remained consistent throughout history, used exclusively as a medical noun without developing any metaphorical or abstract senses in common or formal language.
