About
癀 is a phono-semantic compound character belonging to medical and veterinary terminology. Historically, it denoted jaundice or a severe epidemic disease, primarily affecting domesticated draft animals like cattle and horses. The character's structure is a semantic enclosure: the radical 疒, meaning sickness or disease, indicates the pathological nature of the term. Enclosed within this radical is the phonetic component 黃, pronounced huáng and meaning yellow. This component provides the pronunciation and also supplies a secondary semantic clue, as the yellowing of the skin and eyes is a prominent symptom of jaundice. In historical veterinary and medical texts, 癀 functioned as a highly specific diagnostic label, its use entirely confined to physical pathology.
