Etymology
From Middle English *maskeren, malskren (“to bewilder”) (compare Middle English bimalscren (“to bewitch”)), from Old English *malscrian (attested in derivative malscrung (“enchantment, charm”)), ultimately from Proto-Germanic *malskaz (“haughty”), from Proto-Indo-European *(s)mel- (“to beat, crush, grind”). Cognate with Middle Dutch malsch (“headstrong, zealous”). More at mask.
