About
The character "癞", with its traditional form "癩", is structured as a semantic-phonetic compound combining the disease radical 疒 with the phonetic component 赖 or 賴, indicating a pronunciation akin to "lài" and a semantic link to illness. Originally denoting various skin diseases, its meaning evolved to specify leprosy or a mangy, scabby condition, reflecting a narrowing from broader dermatological references. The components in both forms consistently align with this functional design, where the radical categorizes the character within the domain of ailments and the phonetic element provides auditory distinction.
