Pronunciation

  • IPA: /ˈnɑː.sti/ (UK); /ˈnæs.ti/ (US)[1]

Etymology

It is Middle English nasti, of uncertain origin.[2][3][4][5] Barnhart proposes Old French nastre (“bad, spiteful”), short for villenastre, infamous, from vilein (see villain) and the pejorative -astre, perhaps reinforced by a Scandinavian word;[6][2] Hoad and the Middle English Compendium point to Swedish dialect naskug, nasket, dirty, through early variants naxty and naskie;[3][2] the OED mentions Dutch nestig, dirty, like a bird's nest.[2]

Earliest recorded meaning

Disgustingly dirty, foul: about 1390 in Barnhart, before 1400 in the OED, the late 14th century in Etymonline.[6][7][2]

Semantic evolution

Indecent or obscene, morally filthy, is from about 1600,[2][7] and offensive to taste or smell from before 1548.[7] Of weather, foul or stormy, it is from the 1630s,[2][7] unpleasant or troublesome generally from 1705,[2][7] and of persons, ill-tempered or mean, from 1825.[2] Word Origins notes that the word's force has gradually weakened, though it remains stronger in American than British English;[8] De Vere wrote in 1872 that in America it was not fit to be used before ladies.[2] The noun, an unpleasant thing or person, is from 1935;[2] SOED also records nasty for a Nazi in the mid-20th century.[5]
