About
The character "瘐" is structured with the sickness radical 疒 combined with the component 庾, which serves as a phonetic indicator while also evoking associations with granaries and material measures. Etymologically, the character initially denoted a broad concept of physical wasting or deterioration due to illness, but over centuries its semantic scope narrowed to specifically describe death resulting from malnutrition or disease while in imprisonment, as seen in the term "瘐死". This specialization reflects a shift in usage toward legal and penal contexts, where the character has been employed to document fatalities under conditions of confinement.
