nutmegyoudaoicibaDictYouDict[nutmeg 词源字典]
nutmeg: [13] Etymologically, the nutmeg is the ‘musk-flavoured nut’. The word originated as a partial anglicization of Anglo-Norman *nois mugue, which came via Old French nois muguede from Vulgar Latin *nuce muscāta, literally ‘musky nut’. This ‘musky’ connection, now effectively concealed in English, is still apparent in, for example, German muskatnuss, Swedish muskotnöt, and French noix muscade.

nylonyoudaoicibaDictYouDict
nylon: [20] English has a long history of naming fabrics after their places of origin: denim from Nîmes, for instance, muslin from Mosul, and calico from Calicut in India. It is not surprising, therefore, that the popular myth has grown up that nylon took its name from New York (ny-) and London (-lon). The truth, however, is more prosaic. Du Pont, nylon’s inventors, took the element -on (as in cotton and rayon) and simply added the arbitrary syllable nyl-. The word was coined in 1938, and its plural was in use for ‘nylon stockings’ as early as 1940.
nymphyoudaoicibaDictYouDict
nymph: [14] Greek númphē originally meant ‘bride’ (it was related to Latin nūbere ‘take a husband’, source of English connubial and nubile). It subsequently became extended, however, to ‘beautiful young woman’ and ‘female nature spirit, particularly one frequenting water’, and it was in the latter sense that the word first entered English, via Latin nympha and Old French nimphe. The original sense ‘bride’ lies behind nymphomania, coined in the second half of the 18th century.

NyoudaoicibaDictYouDict
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.
