Pronunciation

  • IPA: /ˈfiːvə/ (UK); /ˈfivɚ/ (US)[1]

Etymology

It is inherited from Old English fēfor, fēfer, borrowed from Latin febris (“fever”),[2][3][4][5] reinforced in Middle English by Anglo-Norman fevre, Old French fievre.[4][6][7] The Latin word is related to fovēre (“to warm”),[2][3][5] perhaps from PIE Proto-Indo-European *dhegh- (“to burn”).[3] It was taken into most Germanic languages, as German Fieber.[3][2]

Earliest recorded meaning

A disease marked by high body temperature: about 1000 in Barnhart and the OED.[2][8]

Semantic evolution

Old English also had hriþ for fever,[3] and the verb feferian.[3] Intense nervous excitement or agitation, as a fever of impatience, is from 1586, the 1580s in Etymonline.[8][3] Fever ague (1338) translated Old French fievre ague, acute fever.[8] Feverish meant causing fever before 1398 and excited, restless from 1634, in Milton.[2] The verb, to throw into a fever, is from 1606 in MWU.[5] Word Origins notes that the plant feverfew was a traditional cure, from Latin febrifugia.[9]
