Origin of feverMiddle English from Old English fefor and from Old French fievre both from Latin febris
- A higher than normal body temperature of a person (or, generally, a mammal), usually caused by disease.
From Middle English, from Old French fievre, reinforced by native Old English fēfor, from Latin febris (“a fever”), from ferveō (“to be hot, burn, boil”); or perhaps literally 'a trembling', akin to Greek φέβεσθαι (febesthai, “to flee affrighted”), φόβος (phobos, “flight, panic fear, fear, terror”).
