Etymology

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”).
Alternative theories have also been proposed, which include:
* From Low German nask (“nasty”) + -y.
* Middle Dutch nestich, nistich ("nasty, dirty, unpleasant" > Modern Dutch nestig (“dirty, filthy, unclean; lazy, cranky”)), perhaps ultimately connected to the Scandinavian word above, or related to *nest (“nest”).
* From Old French nastre (“lowly, strange”), shortened form of villenastre (“infamous, bad”), from vilein (“villain”) + -astre (pejorative suffix), from Latin -aster.
* Other suggestions include Old High German naz (“wet”), hardening of English nesh(y) (“soft”), or alteration of English naughty.
* Modern use of the word is sometimes attributed to the popular and often derogatory 19th century American political cartoons of Thomas Nast, but the word predates him.

From Old English æt þæm eastan hæge (“at the eastern hedged enclosure”).
