Etymology
The word 'gangrene' entered English in the mid-16th century from Latin 'gangraena', which itself was borrowed from Greek 'gangraina'. The Greek term literally meant 'an eating sore' and is related to the verb 'gran', meaning 'to gnaw'. This vivid, literal imagery of a condition that seems to gnaw or consume living tissue was carried directly into the medical Latin terminology. From there, it passed into English, retaining its specific and graphic meaning for tissue death caused by a lack of blood supply. The word's journey encapsulates the direct transfer of a precise medical concept from ancient languages into modern scientific vocabulary.
