Pronunciation

Etymology

It is formed from English nut + -y.[2][3][4][5] The base noun is from Old English hnutu, from Proto-Germanic *hnut- and Proto-Indo-European *kneu- (“nut”).[3] The adjective appears in Middle English as notti,[6] also spelled notty, and the OED holds that these forms are not scribal errors for another adjective of ale.[2] The slang senses grew partly from nuts:[3][2] Green's Dictionary of Slang derives the sense "fond of" from nuts, and suggests that the sense "smart, attractive" comes from the phrase “sweet as a nut”.[7]

Earliest recorded meaning

Nut-like in taste or colour: before 1450, in Lydgate's Siege of Thebes, of "strong notty ale".[2][6] Etymonline dates it to the early 15th century.[3]

Semantic evolution

The sense "producing nuts", of trees and woods, is recorded from 1596 in the OED (the 1660s in Etymonline), and the sense "tasting of nuts" by 1828 in Etymonline.[2][3] Green's Dictionary of Slang finds "smart, attractive" in about 1785;[7] the OED's first record is from Byron's Don Juan (1823), where a footnote explains the word as "conjointly, amorous and fascinating".[2][3] "Fond, infatuated", usually nutty on or upon, is recorded from 1818 in Green, 1819 in the OED and 1821 in Etymonline.[7][2][3] The sense "crazy" is first American and colloquial: the OED dates it from 1892 and Etymonline from 1898,[2][3] and Etymonline thinks it was helped by nut for the head.[3] From 1915 it was also used of a ludicrous idea or object, and in jazz slang from 1955 of exciting music.[2] As a noun it has meant a crazy person since 1942, and in British naval slang chocolate or sweets since 1947.[2] In northern English and Devon dialect it formed compounds such as nutty-cock, a term of endearment, and nutty-crack night, the ninth night before Martinmas.[8]
