Origin of fever

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”).
