Krampus（n.）
also Krampusz, 1872, name of a Germanic folkloric figure who assists St. Nicholas at Christmas-time by punishing the wicked with abduction and/or flogging.
In older German texts often spelled Grampus or Grampes. The name is of uncertain etymology. Encyclopedia Britannica derives it from German Krampen, "claw." OED ventures no further than to suggest "the Germanic base of cramp." This would include among possibilities Bavarian dialect gramp, a scolding word for a naughty child, from Middle High German grimpfen, krimpfen, meaning bent or crooked (for sense evolution compare crook); there is also Swiss dialect grampen, "to grab; to snatch."
Ich sage es jezt immer allen Kindern, daß sie sich nicht erschrecken lassen sollen, und daß der Nikola sowohl, als der Grampus gemeiniglich Hausknechte senn, wie es mir mein Herr Vater gesagt hat. [ "Die Lebkuchen oder der vernünftige Knab," Die Heiligen nach den Volksbegriffen, vol. III, 1791]
