gangrenous

The word 'gangrenous' describes the condition of being afflicted with gangrene, a state of tissue death. Its core, 'gangrene', originates from the Greek 'gangraina', meaning an eating sore, which itself is derived from the verb 'gran', to gnaw—a vivid depiction of the necrosis consuming flesh. This Greek term passed into Latin as 'gangraena', retaining its medical sense. The English adjective was formed by appending the Latinate suffix '-ous', meaning 'full of' or 'characterized by', directly to the noun 'gangrene', thus creating a term that literally means 'characterized by the gnawing sore'.

Structure: gangrene + ous - gangrene: From Latin gangraena, from Greek gangraina (an eating sore, gangrene), related to gran (to gnaw). - ous: A suffix forming adjectives, from Latin -osus (full of, prone to).
