gypsumyoudaoicibaDictYouDict[gypsum 词源字典]
gypsum: [17] The word gypsum originated among the Semitic languages, with a relative or ancestor of Arabic jibs and Hebrew gephes ‘plaster’. Greek adopted this unknown form as gúpsos, which passed into Latin as gypsum. (An Italian descendant of gypsum is gesso ‘plaster’, borrowed by English in the 16th century for ‘plaster as a surface for painting on’.)

gypsyyoudaoicibaDictYouDict
gypsy: [16] It appears that in late medieval Europe, it was widely believed that the Roma people originated in Egypt. They first appeared in England around the beginning of the 16th century, and at first were generally referred to as ‘Egyptians’ (a name which survived well into the 18th century). Egyptian was soon eroded to gyptian, and by the end of the 16th century a new ending had been grafted on to the word to produce gypsy.

G-string (n.)youdaoicibaDictYouDict
1878, geestring, "loincloth worn by an American Indian," originally the string that holds it up, etymology unknown. The spelling with G (1882) is perhaps from influence of violin string tuned to a G (in this sense G string is first recorded 1831), the lowest and heaviest of the violin strings. First used of women's attire 1936, with reference to strip-teasers.
I AM the spirit of the silver "G":
I am silvered sadness,
I am moonlit gladness,
I am that fine madness
Of reverence half, and half of ecstasy
[from "Spirit of the 'G' String," Alfred L. Donaldson, in "Songs of My Violin," 1901]
G.A.R.youdaoicibaDictYouDict

G.I. (adj.)youdaoicibaDictYouDict
also GI, 1936 as an adjective meaning "U.S. Army equipment," American English, apparently an abbreviation of Government Issue, and applied to anything associated with servicemen. Transferred noun sense of "U.S. Army soldier" arose during World War II (first recorded 1943), apparently from the jocular notion that the men themselves were manufactured by the government.

An earlier G.I. (1908) was an abbreviation of galvanized iron, especially in G.I. can, a type of metal trash can; the term was picked up by U.S. soldiers in World War I as slang for a similar-looking type of German artillery shells. But it is highly unlikely that this G.I. came to mean "soldier." No two sources seem to agree on the entire etymology, but none backs the widespread notion that it stands for *General Infantry. GI Joe "any U.S. soldier" attested from 1942 (date in OED is a typo).
gab (v.)youdaoicibaDictYouDict
"talk much," 1786, probably via Scottish and northern England dialect from earlier sense "speak foolishly; talk indiscreetly" (late 14c.), from gabben "to scoff, jeer; mock (someone), ridicule; reproach (oneself)," also "to lie to" (late 13c.), from a Scandinavian source, such as Old Norse gabba "to mock, make fun of," and probably in part from Old French gaber "to mock, jest; brag, boast," which, too, is from Scandinavian. Ultimately perhaps imitative (compare gabble, which might have shaded the sense of this word). Gabber was Middle English for "liar, deceiver; mocker." Related: Gabbed; gabbing.
gab (n.)youdaoicibaDictYouDict
"action of talking," earlier "chatter, loquacity, idle talk" (mid-13c.), also "falsehood, deceit," originally "a gibe, a taunt" (c. 1200), mid-13c., probably from a Scandinavian source akin to Old Norse gabb "mocking, mockery," and in part from Old French gap, gab "joke, jest; bragging talk," which also is probably from Scandinavian (compare gab (v.)). Probably also there is influence from Scottish and northern English gab "the mouth" (see gob); OED reports the word "Not in dignified use." Gift of (the) gab "talent for speaking" is from 1680s.

type of igneous rock, 1823, introduced in geology 1809 by German geologist Christian Leopold von Buch (1774-1853), from Italian (Tuscan) gabbro, a word among the marble-workers, of obscure origin; perhaps from Latin glaber "bare, smooth, bald" (see glad). Related: Gabbroic.

masc. proper name, usually short for Gabriel.
gaberdine (n.)youdaoicibaDictYouDict
"long, loose outer garment," 1510s, from Spanish gabardina, which Watkins says is from Middle French galverdine, from a Germanic source such as Middle High German wallevart "pilgrimage" (German Wallfahrt) in the sense of "pilgrim's cloak." The compound would represent Proto-Germanic *wal- (source also of Old High German wallon "to roam, wander, go on a pilgrimage;" see gallant (adj.)) and Proto-Germanic *faran "to go" (see fare (v.)). The Spanish form perhaps was influenced by Spanish gabán "overcoat" and tabardina "coarse coat." Century Dictionary, however, says the Spanish word is an extended form of gabán and the Spanish word was borrowed and underwent alterations in Old French.
gabfest (n.)youdaoicibaDictYouDict
"session of conversation," 1895, American English colloquial, from gab + -fest.
gable (n.)youdaoicibaDictYouDict
"end of a ridged roof cut off in a vertical plane, together with the wall from the level of the eaves to the apex," mid-14c., "a gable of a building; a facade," from Old French gable "facade, front, gable," from Old Norse gafl "gable, gable-end" (in north of England, the word probably is directly from Norse), according to Watkins, probably from Proto-Germanic *gablaz "top of a pitched roof" (cognates: Middle Dutch ghevel, Dutch gevel, Old High German gibil, German Giebel, Gothic gibla "gable"). This is traced to a PIE *ghebh-el- "head," which seems to have yielded words meaning both "fork" (such as Old English gafol, geafel, Old Saxon gafala, Dutch gaffel, Old High German gabala "pitchfork," German Gabel "fork;" Old Irish gabul "forked twig") and "head" (such as Old High German gibilla, Old Saxon gibillia "skull").
Possibly the primitive meaning of the words may have been 'top', 'vertex'; this may have given rise to the sense of 'gable', and this latter to the sense of 'fork', a gable being originally formed by two pieces of timber crossed at the top supporting the end of the roof-tree." [OED]
Related: Gabled; gables; gable-end.
