c. 1300, from Old French niece "niece, granddaughter" (12c., Modern French nièce), earlier niepce, from Latin neptia (also source of Portuguese neta, Spanish nieta), a more decidedly feminine form of neptis "granddaughter," in Late Latin "niece," fem. of nepos "grandson, nephew" (see nephew).

niggard (n.)youdaoicibaDictYouDict
"mean person, miser," late 14c., nygart, of uncertain origin. The suffix suggests French origin (see -ard), but the root word is possibly from earlier nig "stingy" (c. 1300), perhaps from a Scandinavian source related to Old Norse hnøggr "stingy," from Proto-Germanic *khnauwjaz (source of Swedish njugg "close, careful," German genau "precise, exact"), and to Old English hneaw "stingy, niggardly," which did not survive in Middle English.
niggardly (adj.)youdaoicibaDictYouDict
1560s, from niggard + -ly (1).
It was while giving a speech in Washington, to a very international audience, about the British theft of the Elgin marbles from the Parthenon. I described the attitude of the current British authorities as "niggardly." Nobody said anything, but I privately resolved -- having felt the word hanging in the air a bit -- to say "parsimonious" from then on. [Christopher Hitchens, "The Pernicious Effects of Banning Words," Slate.com, Dec. 4, 2006]
As an adverb from 1520s. Related: Niggardliness.
nigger (n.)youdaoicibaDictYouDict
1786, earlier neger (1568, Scottish and northern England dialect), from French nègre, from Spanish negro (see Negro). From the earliest usage it was "the term that carries with it all the obloquy and contempt and rejection which whites have inflicted on blacks" [cited in Gowers, 1965, probably Harold R. Isaacs]. But as black inferiority was at one time a near universal assumption in English-speaking lands, the word in some cases could be used without deliberate insult. More sympathetic writers late 18c. and early 19c. seem to have used black (n.) and, after the American Civil War, colored person.
"You're a fool nigger, and the worst day's work Pa ever did was to buy you," said Scarlett slowly. ... There, she thought, I've said "nigger" and Mother wouldn't like that at all. [Margaret Mitchell, "Gone With the Wind," 1936]
Also applied by English settlers to dark-skinned native peoples in India, Australia, Polynesia. The reclamation of the word as a neutral or positive term in black culture (not universally regarded as a worthwhile enterprise), often with a suggestion of "soul" or "style," is attested first in the U.S. South, later (1968) in the Northern, urban-based Black Power movement.

Used in combinations (such as nigger-brown) since 1840s for various dark brown or black hues or objects; euphemistic substitutions (such as Zulu) began to appear in these senses c. 1917. Brazil nuts were called nigger toes by 1896. Variant niggah, attested from 1925 (without the -h, from 1969), is found usually in situations where blacks use the word. Nigra (1944), on the other hand, in certain uses reflects a pronunciation of negro meant to suggest nigger, and is thus deemed (according to a 1960 slang dictionary) "even more derog[atory] than 'nigger.' " Slang phrase nigger in the woodpile attested by 1800; "A mode of accounting for the disappearance of fuel; an unsolved mystery" [R.H. Thornton, "American Glossary," 1912]. Nigger heaven "the top gallery in a (segregated) theater" first attested 1878 in reference to Troy, N.Y.
niggerhead (n.)youdaoicibaDictYouDict

niggle (v.)youdaoicibaDictYouDict

nigh (adv.)youdaoicibaDictYouDict
"near," Old English neah (West Saxon), neh (Anglian), common Germanic (cognates: Old Saxon nah, Old Frisian nei, Middle Dutch, Dutch na, Old High German nah, German nah, Gothic nehwa), with no cognates outside Germanic. The Old English progression was neah - near - niehsta, for "nigh - near - next." But the comparative near and the superlative nehst (see next) gradually evolved into separate words not felt as related to nigh. New comparative and superlative forms nigher, nighest developed 14c. as phonetic changes obscured the original relationships. As an adjective from Middle English.
night (n.)youdaoicibaDictYouDict
Old English niht (West Saxon neaht, Anglian næht, neht) "night, darkness;" the vowel indicating that the modern word derives from oblique cases (genitive nihte, dative niht), from Proto-Germanic *nakht- (cognates: Old Saxon and Old High German naht, Old Frisian and Dutch nacht, German Nacht, Old Norse natt, Gothic nahts).

The Germanic words are from PIE *nekwt- "night" (cognates: Greek nuks "a night," Latin nox, Old Irish nochd, Sanskrit naktam "at night," Lithuanian naktis "night," Old Church Slavonic nosti, Russian noch', Welsh henoid "tonight"), according to Watkins, probably from a verbal root *neg- "to be dark, be night." For spelling with -gh- see fight.
The fact that the Aryans have a common name for night, but not for day (q.v.), is due to the fact that they reckoned by nights. [Weekley]
Compare German Weihnachten "Christmas." In early times, the day was held to begin at sunset, so Old English monanniht "Monday night" was the night before Monday, or what we would call Sunday night. The Greeks, by contrast, counted their days by mornings.

To work nights preserves the Old English genitive of time. Night shift is attested from 1710 in the sense of "garment worn by a woman at night" (see shift (n.1)); meaning "gang of workers employed after dark" is from 1839. Night soil "excrement" (1770) is so called because it was removed (from cesspools, etc.) after dark. Night train attested from 1838. Night life "habitual nocturnal carousing" attested from 1852.
