"genetic constitution of an individual," 1910, from German Genotypus (Wilhelm Johannsen, 1909); see gene + type (n.). Earlier the same word was used with a sense of "type-species of a genus" (1897); in this case, the first element is from genus.[genotype etymology, genotype origin, 英语词源]
genre (n.)youdaoicibaDictYouDict
1770, "particular style of art," a French word in English (nativized from c. 1840), from French genre "kind, sort, style" (see gender (n.)). Used especially in French for "independent style." In painting, as an adjective, "depicting scenes of ordinary life" (a domestic interior or village scene, as compared to landscape, historical, etc.) from 1849.
Genro (n.)youdaoicibaDictYouDict

gens (n.)youdaoicibaDictYouDict
1847, in reference to ancient Rome, "tribe, clan, house (of families having a name and certain religious rites in common and a presumed common origin)," from Latin gens (genitive gentis) "race, clan, nation" (see genus).
gent (n.)youdaoicibaDictYouDict
colloquial shortening of gentleman, by 17c. (in early uses it is difficult to distinguish the shortening from the common abbreviation gent.), which is perhaps the origin of this use. "Early in the nineteenth century the word was colloquial and slightly jocular; about 1840 its use came to be regarded as a mark of low breeding" [OED].
genteel (adj.)youdaoicibaDictYouDict
1590s, "fashionably elegant; suitable to polite society, characteristic of a lady or gentleman; decorous in manners or behavior," from Middle French gentil "stylish, fashionable, elegant; nice, graceful, pleasing," from Old French gentil "high-born, noble" (11c.); a reborrowing (with evolved senses) of the French word that had early come into English as gentle (q.v.), with French pronunciation and stress preserved to emphasize the distinction. The Latin source of the French word is the ancestor of English gentile, but the main modern meaning of that word is from a later Scriptural sense in Latin. See also jaunty. OED 2nd ed. reports genteel "is now used, except by the ignorant, only in mockery" (a development it dates from the 1840s).
gentian (n.)youdaoicibaDictYouDict
type of herb, late 14c., genciane, from Old French genciane (13c.) and directly from Latin gentiana, said by Pliny to be named for Gentius, king of ancient Illyria who discovered its properties. This likely is a folk-etymology, but the word may be Illyrian nonetheless, because the suffix -an frequently occurs in Illyrian words.
gentile (n.)youdaoicibaDictYouDict
"one who is not a Jew," c. 1400; earlier "one who is not a Christian, a pagan" (late 14c.), from Late Latin noun use of Latin gentilis "of the same family or clan, of or belonging to a Roman gens," from gens (genitive gentis) "race, clan" (see genus, and compare gentle).

The Latin adjective also meant "of or belonging to the same nation," hence, as a noun, gentiles (plural) might mean "men of family; persons belonging to the same family; fellow countrymen, kinsmen," but also "foreigners, barbarians" (as opposed to Romans), those bound only by the Jus Gentium, the "law of nations," defined as "the law that natural reason establishes among all mankind and is followed by all peoples alike."

The Latin word then was used in the Vulgate to translate Greek ethnikos (see ethnic), from ta ethne "the nations," which translated Hebrew ha goyim "the (non-Jewish) nations" (see goy). Hence in Late Latin, after the Christianization of Rome, gentilis also could mean "pagans, heathens," as opposed to Christians. Based on Scripture, gentile also was used by Mormons (1847) and Shakers (1857) to refer to those not of their profession.
gentility (n.)youdaoicibaDictYouDict
mid-14c., "nobility of birth, gentle birth," from Old French gentilité (14c.), from Latin gentilitatem (nominative gentilitas) "relationship in the same family or clan," from gentilis "of the same family or clan" (see gentle; also compare gentry). From 1640s as "social superiority." Meaning "state of being gentile" is rare.
gentle (adj.)youdaoicibaDictYouDict
early 13c., gentile, gentle "well-born, of noble rank or family," from Old French gentil/jentil "high-born, worthy, noble, of good family; courageous, valiant; fine, good, fair" (11c., in Modern French "nice, graceful, pleasing; fine, pretty") and directly from Latin gentilis "of the same family or clan," in Medieval Latin "of noble or good birth," from gens (genitive gentis) "race, clan," from root of gignere "beget," from PIE root *gene- "to give birth, beget" (see genus).

Sense evolved in English and French to "having the character or manners of one of noble rank or birth," varying according to how those were defined. From mid-13c. in English as "gracious, kind" (now obsolete), manners prescribed for Christian or chivalrous nobility. From late 13c. as "courteous, polite, well-bred, charming;" c. 1300 as "graceful, beautiful." Meaning "mild, tender; easy; not harsh" (of animals, things, persons) is from 1550s. Older sense remains in gentleman, and compare gentile (adj.), an alternative form which tends to keep the Biblical senses of the Latin word (though gentle in Middle English sometimes meant "pagan, heathen"), and genteel, which is the same word borrowed again from French. From 1823 as "pertaining to the fairies."
gentleman (n.)youdaoicibaDictYouDict
c. 1200, perhaps mid-12c., "well-born man, man of good family or birth," also extended to Roman patricians and ancient Greek aristocrats, from gentle + man (n.); the compound probably is modeled on Old French gentilhomme (the English gentleman itself was borrowed into French in 18c.).

Given specific uses in late Middle English (small gentleman, gentleman-of-arms, gentleman-usher, etc.), hence in England the word often meant any man above the social rank of a yeoman, including the nobility, but it was sometimes restricted to those who bear a coat of arms but not a title; in U.S., "man of property, not engaged in business or a profession" (1789). The English word from the beginning also had a special sense "nobleman whose behavior conforms to the ideals of chivalry and Christianity," and gentleman came to be used loosely for any man of good breeding, courtesy, kindness, honor, strict regard for the feelings of others, etc.
The Gentleman is always truthful and sincere; will not agree for the sake of complaisance or out of weakness ; will not pass over that of which he disapproves. He has a clear soul, and a fearless, straightforward tongue. On the other hand he is not blunt and rude. His truth is courteous; his courtesy, truthful; never a humbug, yet, where he truthfully can, he prefers to say pleasant things. [J.R. Vernon, "Contemporary Review," 1869]
Eventually, in polite use, it came to mean a man in general, regardless of social standing. Related: Gentlemen. Gentleman's agreement is first attested 1929. Gentleman farmer recorded from 1749, "A man of means who farms on a large scale, employs hands, and does little or none of the work himself" [Craigie, "Dictionary of American English"].
gentlemanly (adj.)youdaoicibaDictYouDict
early 15c., "well-behaved, courteous," from gentleman + -ly (1).
gentleness (n.)youdaoicibaDictYouDict
c. 1300, "inherited nature," from gentle + -ness. Meaning "freedom from harshness or violence" is from 1610s.
gentlewoman (n.)youdaoicibaDictYouDict
early 13c., "woman of good family or breeding," from gentle + woman. It seems never to have developed the looser senses in gentleman; Bret Harte tried gentlewomanliness.
gently (adv.)youdaoicibaDictYouDict
early 14c., "befitting one of gentle rank, as of good family," from gentle + -ly (2). Meaning "quietly, softly, without rudeness, gradually" is from 1550s.
gentrification (n.)youdaoicibaDictYouDict
1973, noun of action from gentrify.
gentrify (v.)youdaoicibaDictYouDict
"renovate inner-city housing to middle-class standards," by 1972, from gentry + -fy. Related: Gentrified, which was used from early 19c. of persons.
gentry (n.)youdaoicibaDictYouDict
c. 1300, "nobility of rank or birth;" mid-14c., "a fashion or custom of the nobility;" late 14c., "nobility of character," from Old French genterie, genterise, variant of gentelise "noble birth, aristocracy; courage, honor; kindness, gentleness," from gentil "high-born, noble, of good family" (see gentle). Meaning "noble persons, the class of well-born and well-bred people" is from 1520s in English, later often in England referring to the upper middle class, persons of means and leisure but below the nobility. Earlier in both senses was gentrice (c. 1200 as "nobility of character," late 14c. as "noble persons"), and gentry in early use also might have been regarded as a singular of that. In Anglo-Irish, gentry was a name for "the fairies" (1880), and gentle could mean "enchanted" (1823).
genuflect (v.)youdaoicibaDictYouDict
"to bend the knee" as an act of worship or respect, 1620s, back-formation from genuflection. Related: Genuflected; genuflecting.
genuflection (n.)youdaoicibaDictYouDict
"act of bending the knee," especially in worship, early 15c., from Middle French génuflexion (14c.) and directly from Medieval Latin genuflectionem (nominative genuflexio) "bending of the knee," noun of action from past participle stem of Late Latin genuflectere "genuflect," properly genu flectere "to bend the knee," from Latin genu "knee" (see knee (n.)) + flectere "to bend" (see flexible).
