From Middle English nasty, nasti, naxty, naxte (“unclean, filthy”), whence also Early Modern English nasky (“nasty”), of obscure origin. Probably from earlier Middle English *naskty, *naskedy, from Middle English *nasked (“dirty, messy”) + -y, ultimately of North Germanic origin (comparable to Danish nasket (“dirty, foul, unpleasant”), Swedish naskot (“dirty, filthy”), Swedish naskig, naskug (“nasty, dirty, messy”)), themselves all probably related to Proto-Germanic *hnaskuz (“tender, soft”). Likely doublet of nesh and nosh. Cognate with Scots nastie, nestie (“dirty, filthy”).
