Origin of fiendMiddle English, from Old English fēond; see pē(i)- in Indo-European roots.
From Middle English feend (“enemy, demon”), from Old English fēond (“enemy”), from Proto-Germanic *fijandz. Cognate with Old Norse fjándi (Icelandic fjandi, Danish fjende, Swedish fiende), West Frisian fijân, Low German Feend, Fiend, Dutch vijand, German Feind, Gothic (fijands), all of them meaning foe. The Old Norse and Gothic terms are present participles of the corresponding verbs fjá/fijan, to hate. Akin to Sanskrit पियति (piyati, “(he) reviles”).
