dysentery

The word 'dysentery' is a direct borrowing from the Latin 'dysenteria', which itself originated from the Greek 'dysenteria'. The Greek term is a compound of the prefix 'dys-', meaning 'bad' or 'difficult', and 'enteron', meaning 'intestine'. The literal construction 'bad intestine' precisely describes the disease's primary symptom: a severe, painful infection of the bowels. This medical term has remained remarkably stable in form and meaning from its ancient origins, passing through Latin and Old French before entering Middle English, always retaining its core logic of denoting a disorder of the intestines.

Structure: dys (bad) + enter (intestine) + y (noun suffix) dys- (Greek origin, a prefix meaning 'bad', 'difficult', or 'faulty'); enter- (Greek origin, from 'enteron', meaning 'intestine' or 'gut'); -y (English suffix of Greek/Latin origin, forming nouns denoting a state, condition, or action).
