英文词源
not
**not: **[14] In Old English and early Middle English the simple particle _ne _was used for making negative sentences. But it was evidently often felt to be in need of some reinforcement, for purposes of emphasis, and to do this job _noht _was brought in. Ancestor of modern English _nought _[OE], it was a compound formed from _ne _and _ōwiht _‘anything’ (precursor of archaic modern English ought).
By the end of the 13th century this was being widely used as the sole negator in sentences, the _ne _having been dispensed with, and we soon find spellings reflecting the sort of reduction in pronunciation from _nought _to _not _that one would expect from its often weakly-stressed position.
=> nought, ought
not
negative particle, mid-13c., unstressed variant of noht, naht "in no way" (see naught). As an interjection to negate what was said before or reveal it as sarcasm, it is first attested 1900; popularized 1989 by "Wayne's World" sketches on "Saturday Night Live" TV show. To not know X from Y (one's ass from one's elbow, shit from Shinola, etc.) was a construction first attested c. 1930. Double negative construction not un- was derided by Orwell, but is persistent and ancient in English, popular with Milton and the Anglo-Saxon poets.
