limerickyoudaoicibaDictYouDict[limerick 词源字典]
limerick: [19] The best-known writer of limericks is of course Edward Lear, but ironically the term limerick was not born until after Lear was dead. It is first recorded in 1896, and is said to have come from a Victorian custom of singing nonsense songs at parties, in the limerick rhymescheme (aabba), which always ended with the line ‘Will you come up to Limerick?’ (Limerick of course being a county and town in Ireland).

mendyoudaoicibaDictYouDict
mend: [12] Mend originated as a shortened form of amend [13] – or rather, of the Old French source of amend, which did not arrive in English until after mend. The Old French verb was amender, a descendant of Vulgar Latin *admendāre ‘remove faults, correct’. This in turn was an alteration of classical Latin ēmendāre (source of English emend [15]), a compound verb formed from the prefix exdenoting ‘removal’ and menda, mendum ‘fault, defect’. (Other Latin derivatives of mendum were mendīcus ‘injured’, which was used as a noun meaning ‘beggar’ – hence English mendicant [15]; and perhaps mendāx ‘speaking faultily’, hence ‘lying’, from which English gets mendacious [17].)
=> amend, emend, mendicant
offyoudaoicibaDictYouDict
off: [OE] Off originated simply as the adverbial use of of. The spelling off, denoting the extra emphasis given to the adverb, began to appear in the 15th century, but the orthographic distinction between off for the adverb, and for prepositional uses associated with it (‘removal, disengagement’), and of for the ordinary preposition did not become firmly established until after 1600.

sophisticateyoudaoicibaDictYouDict
sophisticate: [14] As those who hanker for the ancestral meanings of words never tire of pointing out, sophisticated originally meant ‘adulterated, corrupted’. The modern approbatory sense ‘worldly-wise, cultured’ did not emerge (via an intermediate ‘lacking primitive or original naturalness or naivety’) until the end of the 19th century; and ‘refined and elaborate’ (as in ‘a sophisticated missile system’) is more recent still, not being recorded until after World War II.

The verb was adapted from the past participle of medieval Latin sophisticāre. This was derived from Latin sophisticus, a borrowing from Greek sophistikós, which in turn was derived from sophistés, a noun which meant literally ‘expert, deviser’, but was also used for a school of 5thcentury BC Greek philosophers (the Sophists) who came to be despised for their specious and intellectually dishonest reasoning (hence English sophistry [14]). Sophistés itself came via sophízesthai ‘play subtle tricks’ from sophós ‘skilled, clever, wise’, a word of unknown origin. Sophomore ‘second-year student’ [17] is an alteration of an earlier sophumer ‘arguer’, a derivative of sophum, which is a now defunct variant of sophism.

=> sophistry, sophomore
air force (n.)youdaoicibaDictYouDict
1917, from air (n.1) + force (n.); first attested with creation of the Royal Air Force. There was no United States Air Force until after World War II. The Air Corps was an arm of the U.S. Army. In 1942, the War Department reorganized it and renamed it Army Air Forces. The National Security Act of 1947 created the Department of the Air Force, headed by a Secretary of the Air Force, and the U.S.A.F.
Arabic (adj.)youdaoicibaDictYouDict
early 14c., from Old French Arabique (13c.), from Latin Arabicus "Arabic" (see Arab). Old English used Arabisc "Arabish." Originally in reference to gum arabic; noun meaning "Arabic language" is from late 14c.

Arabic numerals (actually Indian) first attested 1727; they were introduced in Europe by Gerbert of Aurillac (later Pope Sylvester II) after a visit to Islamic Spain in 967-970. A prominent man of science, he taught in the diocesan school at Reims, but the numbers made little headway against conservative opposition in the Church until after the Crusades. The earliest depiction of them in English, in "The Crafte of Nombrynge" (c. 1350) correctly identifies them as "teen figurys of Inde."
arrow (n.)youdaoicibaDictYouDict
early 14c., from Old English arwan, earlier earh "arrow," possibly borrowed from Old Norse ör (genitive örvar), from Proto-Germanic *arkhwo (cognates: Gothic arhwanza), from PIE root *arku- "bow and/or arrow," source of Latin arcus (see arc (n.)). The ground sense would be "the thing belonging to the bow," perhaps a superstitious avoidance of the actual name.

A rare word in Old English, where more common words for "arrow" were stræl (cognate with the word still common in Slavic, once prevalent in Germanic, too; meaning related to "flash, streak") and fla, flan, a North Germanic word, perhaps originally with the sense of "splinter." Stræl disappeared by 1200; fla lingered in Scottish until after 1500. Meaning "a mark like an arrow in cartography, etc." is from 1834.
Robyn bent his joly bowe,
Therein he set a flo.
["Robyn and Gandelyn," in minstrel book, c. 1450, in British Museum]
cease-fire (n.)youdaoicibaDictYouDict
also ceasefire, "a cessation of shooting," 1916, from verbal phrase cease fire, 1847 as a military command (formerly also signaled by bugles), from cease (v.) + fire (n.) in the gunnery sense. Generally two words until after mid-20c.
cod (n.)youdaoicibaDictYouDict
large sea fish, mid-14c. (late 13c. in a surname, Thomas cotfich), of unknown origin; despite similarity of form it has no conclusive connection to the widespread Germanic word for "bag" (represented by Old English codd, preserved in codpiece). Cod-liver oil known since at least 1610s, was recommended medicinally since 1783, but not popular as a remedy until after 1825.
continental driftyoudaoicibaDictYouDict
1925, a translation of German Kontinentalverschiebung, proposed 1912 by German scientist Alfred Wegener (1880-1930); the theory was not widely accepted until after c. 1950.
discreet (adj.)youdaoicibaDictYouDict
mid-14c., "morally discerning, prudent, circumspect," from Old French discret "discreet, sensible, intelligent, wise," from Latin discretus "separated, distinct," in Medieval Latin "discerning, careful," past participle of discernere "distinguish" (see discern). Meaning "separate, distinct" in English is late 14c.

Spellings discrete and nativized discreet co-existed until after c. 1600, when discreet became the common word for "careful, prudent," and discrete was maintained in philosophy, medicine, music and other disciplines that remembered Latin and made effort to obey it. Related: Discreetly.
GeorgeyoudaoicibaDictYouDict
masc. personal name, from French Georges, Late Latin Georgius, from Greek Georgos "husbandman, farmer," properly an adjective, "tilling the ground," from ge "earth" (see Gaia) + ergon "work" (see organ). The name introduced in England by the Crusaders (a vision of St. George played a key role in the First Crusade), but not common until after the Hanoverian succession (18c.). St. George began to be recognized as patron of England in time of Edward III, perhaps because of his association with the Order of the Garter (see garter). His feast day is April 23. The legend of his combat with the dragon is first found in "Legenda Aurea" (13c.). The exclamation by (St.) George! is recorded from 1590s.
The cult of George reached its apogee in the later Middle Ages: by then not only England, but Venice, Genoa, Portugal, and Catalonia regarded him as their patron: for all he was the personification of the ideals of Christian chivalry. [The Oxford Dictionary of Saints]
middle (adj.)youdaoicibaDictYouDict
Old English middel, from West Germanic *middila (cognates: Old Frisian middel, Old Saxon middil, Middle Low German, Dutch middel, Old High German mittil, German mittel), from Proto-Germanic *medjaz (see mid). Middle name attested from 1815; as "one's outstanding characteristic," colloquial, from 1911, American English.
According to Mr. H.A. Hamilton, in his "Quarter Sessions from Queen Elizabeth," the practice of giving children two Christian names was unknown in England before the period of the Stuarts, was rarely adopted down to the time of the Revolution, and never became common until after the Hanoverian family was seated on the throne. "In looking through so many volumes of county records," he says, "I have, of course, seen many thousands and tens of thousands of proper names, belonging to men of all ranks and degrees,--to noblemen, justices, jurymen, witnesses, sureties, innkeepers, hawkers, paupers, vagrants, criminals, and others,--and in no single instance, down to the end of the reign of Anne, have I noticed any person bearing more than one Christian name ...." [Walsh]
Middle school attested from 1838, originally "middle-class school, school for middle-class children;" the sense in reference to a school for grades between elementary and high school is from 1960. Middle management is 1957. Middle-of-the-road in the figurative sense is attested from 1894; edges of a dirt road can be washed out and thus less safe. Middle finger so called from c. 1000.
non-fiction (adj.)youdaoicibaDictYouDict
also nonfiction, 1866, a librarians' word, first in the reports of the Boston Public Library, from non- + fiction. Apparently not in widespread use until after 1900.
relevant (adj.)youdaoicibaDictYouDict
"pertinent to the matter at hand," 1550s, from Middle French relevant "depending upon," originally "helpful," from Medieval Latin relevantem (nominative relevans), from stem of Latin relevare "to lessen, lighten" (see relieve). Not generally used until after 1800.
reticence (n.)youdaoicibaDictYouDict
c. 1600, from Middle French réticence (16c.), from Latin reticentia "silence, a keeping silent," from present participle stem of reticere "keep silent," from re- (see re-), + tacere "be silent" (see tacit). "Not in common use until after 1830" [OED].
sugar (n.)youdaoicibaDictYouDict
late 13c., sugre, from Old French sucre "sugar" (12c.), from Medieval Latin succarum, from Arabic sukkar, from Persian shakar, from Sanskrit sharkara "ground or candied sugar," originally "grit, gravel" (cognate with Greek kroke "pebble"). The Arabic word also was borrowed in Italian (zucchero), Spanish (azucar, with the Arabic article), and German (Old High German zucura, German Zucker), and its forms are represented in most European languages (such as Serbian cukar, Polish cukier, Russian sakhar).

Its Old World home was India (Alexander the Great's companions marveled at the "honey without bees") and it remained exotic in Europe until the Arabs began to cultivate it in Sicily and Spain; not until after the Crusades did it begin to rival honey as the West's sweetener. The Spaniards in the West Indies began raising sugar cane in 1506; first grown in Cuba 1523; first cultivated in Brazil 1532. The reason for the -g- in the English word is obscure (OED compares flagon, from French flacon). The pronunciation shift from s- to sh- is probably from the initial long vowel sound syu- (as in sure).

As a type of chemical compound from 1826. Slang "euphemistic substitute for an imprecation" [OED] is attested from 1891. As a term of endearment, first recorded 1930. Sugar-cane is from 1560s. Sugar-maple is from 1731. Sugar loaf was originally a moulded conical mass of refined sugar (early 15c.); now obsolete, but sense extended 17c. to hills, hats, etc. of that shape.
teachable (adj.)youdaoicibaDictYouDict
late 15c., "capable of being taught" (of persons), from teach (v.) + -able. Of subjects, from 1660s. Teachable moment, attested from 1917, not common until after c. 1960, extends the sense to "appropriate for instruction." Related: Teachableness.
tomato (n.)youdaoicibaDictYouDict
1753, earlier tomate (c. 1600), from Spanish tomate (mid-16c.) from Nahuatl (Aztecan) tomatl "a tomato," said to mean literally "the swelling fruit," from tomana "to swell." Spelling probably influenced by potato (1565). Slang meaning "an attractive girl" is recorded from 1929, on notion of juicy plumpness.

A member of the nightshade family, all of which contain poisonous alkaloids. Introduced in Europe from the New World, by 1550 they regularly were consumed in Italy but grown only as ornamental plants in England and not eaten there or in the U.S. at first. An encyclopedia of 1753 describes it as "a fruit eaten either stewed or raw by the Spaniards and Italians and by the Jew families of England." Introduced in U.S. 1789 as part of a program by then-Secretary of State Thomas Jefferson, but not commonly eaten until after c. 1830.

Alternative name love apple and alleged aphrodisiac qualities have not been satisfactorily explained; perhaps from Italian name pomodoro, taken as from adorare "to adore," but probably rather from d'or "of gold" (in reference to color) or de Moro "of the Moors."
urchin (n.)youdaoicibaDictYouDict
c. 1300, yrichon "hedgehog," from Old North French *irechon (cognates: Picard irechon, Walloon ireson, Hainaut hirchon), from Old French herichun "hedgehog" (Modern French hérisson), formed with diminutive suffix -on + Vulgar Latin *hericionem, from Latin ericius "hedgehog," enlarged form of er, originally *her, from PIE root *ghers- "to bristle" (cognates: Greek kheros "hedgehog;" see horror).

Still used for "hedgehog" in non-standard speech in Cumbria, Yorkshire, Shropshire. Applied throughout 16c. to people whose appearance or behavior suggested hedgehogs, from hunchbacks (1520s) to goblins (1580s) to bad girls (1530s); meaning "poorly or raggedly clothed youngster" emerged 1550s, but was not in frequent use until after c. 1780. Sea urchin is recorded from 1590s (a 19c. Newfoundland name for them was whore's eggs); Johnson describes it as "a kind of crabfish that has prickles instead of feet."
VIP (n.)youdaoicibaDictYouDict
also V.I.P., 1933, initialism (acronym) for very important person or personage; not common until after World War II.
At most, the greatest persons, are but great wens, and excrescences; men of wit and delightfull conversation, but as moales for ornament, except they be so incorporated into the body of the world, that they contribute something to the sustentation of the whole. [John Donne, letter to Sir Henry Goodere, Sept. 1608]
walk (v.)youdaoicibaDictYouDict
"travel on foot," c. 1200, a merger of two verbs, 1. Old English wealcan "to toss, roll, move round" (past tense weolc, past participle wealcen), and 2. wealcian "to roll up, curl," from Proto-Germanic *welk- (cognates: Old Norse valka "to drag about," Danish valke "to full" (cloth), Middle Dutch walken "to knead, press, full" (cloth), Old High German walchan "to knead," German walken "to full"), perhaps ultimately from PIE root *wel- (3) "to turn, roll" (see volvox).

The shift in sense is perhaps from a colloquial use of the Old English word or via the sense of "to full cloth" (by treading on it), though this sense does not appear until after the change in meaning. In 13c. it is used of snakes and the passage of time, and in 15c. of wheeled carts. "Rarely is there so specific a word as NE walk, clearly distinguished from both go and run" [Buck]. Meaning "to go away" is recorded from mid-15c. Transitive meaning "to exercise a dog (or horse)" is from late 15c.; meaning "to escort (someone) in a walk" is from 1620s. Meaning "move (a heavy object) by turning and shoving it in a manner suggesting walking" is by 1890. To walk it off, of an injury, etc., is from 1741. Related: Walked; walking.
wh-youdaoicibaDictYouDict
respelling of Old English hw- attested from 11c., but not the common form until after c. 1400. It represents PIE *kw-; in German reduced to simple w-, in Scandinavian as hv-, kv-, or v-.

Also added to some borrowed words (whisk, whiskey) and some native words formerly spelled with simple w- or h- (whole, whore). In the 15c. flowering of its use it also threatened to change the spelling of hot, home and many more. In northern English 16c.-18c., sometimes altered to quh- (see Q). Proper pronunciation has been much in dispute in educated speech.
