personification of riches and worldliness, mid-14c., from Late Latin mammona, from Ecclesiastical Greek mamōnas, from Aramaic mamona, mamon "riches, gain;" a word left untranslated in Greek New Testament (Matthew vi.24, Luke xvi.9-13), retained in the Vulgate, and regarded mistakenly by medieval Christians as the name of a demon who leads men to covetousness.
also nymphet, nymphete, "sexually attractive young girl," 1955, introduced by Vladimir Nabokov (1899-1977) in his novel "Lolita" to describe an alluring (in the minds of some men) girl age 9 to 14; from nymph + diminutive suffix. Nymphet was used from 17c. in sense "a little nymph," but this was poetic only by late 19c.
inert gaseous element, 1898, coined by its discoverers (Sir William Ramsay and Morris W. Travers) from Greek krypton, neuter of adjective kryptos "hidden" (see crypt); so called because it remained undiscovered for so long and was so difficult to find. Scientific American (July 9, 1898) announced it as "the discovery of yet another element."
"9 times ten; the number which is one more than eighty-nine or 10 less than one hundred; a symbol representing this number;" Middle English nīntī (late 13c.), from Old English nigontig, from nine + -tig "group of ten" (see -ty (1)). Cognate with Old Frisian niontich, Middle Dutch negentich, Dutch negentig, German neunzig, Old Norse nintigir.
c. 1400, promisen, "make a promise of," from promise (n.). Meaning "afford reason to expect" is from 1590s. Related: Promised; promising. In Middle English also promit (promitten), from the Latin verb. The promised land (1530s, earlier lond of promission, mid-13c.; province of promissioun, late 15c.) is a reference to the land of Canaan promised to Abraham and his progeny (Hebrew xi:9, etc.; Greek ten ges tes epangelias).
"1 more than eighteen, nine more than ten; the cardinal number composed of 10 and 9; a symbol representing this number;" Middle English nīntene, from late Old English nigontene (Anglian), nigontyne (West Saxon); see nine + -teen.
