N词源

N

in nickname, newt, and British dialectal naunt, the -n- belongs to a preceding indefinite article an or possessive pronoun mine.Other examples of this from Middle English manuscripts include a neilond (\"an island,\" early 13c.), a narawe (\"an arrow,\" c. 1400), a nox (\"an ox,\" c. 1400), a noke (\"an oak,\" early 15c.), a nappyle (\"an apple,\" early 15c.), a negge (\"an egg,\" 15c.). In 16c., an idiot sometimes became a nidiot, which, with still-common casual pronunciation, became nidget, which, alas, has not survived.The process also worked in surnames, from oblique cases of Old English at \"by, near,\" as in Nock/Nokes/Noaks from atten Oke \"by the oak;\" Nye from atten ye \"near the lowland;\" and see Nashville.But it is more common for an English word to lose an -n- to a preceding a: apron, auger, adder, umpire, humble pie, etc. The mathematical use of n for \"an indefinite number\" is first recorded 1852, in to the nth power.
