ace (n.)[ace 词源字典]: c. 1300, "one at dice," from Old French as "one at dice," from Latin as "a unit, one, a whole, unity;" also the name of a small Roman coin ("originally one pound of copper; reduced by depreciation to half an ounce" [Lewis]), perhaps originally Etruscan and related to Greek eis "one" (from PIE *sem- "one, as one"), or directly from the Greek word.

In English, it meant the side of the die with only one mark before it meant the playing card with one pip (1530s). Because this was the lowest roll at dice, ace was used metaphorically in Middle English for "bad luck" or "something of no value;" but as the ace is often the highest playing card, the extended senses based on "excellence, good quality" arose 18c. as card-playing became popular. Ace in the hole in the figurative sense of "concealed advantage" is attested from 1904, from crooked stud poker deals.

Meaning "outstanding pilot" dates from 1917 (technically, in World War I aviators' jargon, one who has brought down 10 enemy planes, though originally in reference to 5 shot down), from French l'ace (1915), which, according to Bruce Robertson (ed.) "Air Aces of the 1914-1918 War" was used in prewar French sporting publications for "top of the deck" boxers, cyclists, etc. Sports meaning of "point scored" (1819) led to that of "unreturnable serve" (1889).[ace etymology, ace origin, 英语词源]
Boeotian (adj.): 1590s, "ignorant, dull," from Boeotia, district around Thebes in ancient Greece (said to have been so called for its cattle pastures; Greek bous = "ox"), whose inhabitants were characterized as proverbially dull and countrified by their neighbors, the Athenians. The Boeotians presumably held reciprocal opinions, but their great writers, Plutarch and Pindar, though patriots, are full of praise for Athenian deeds and institutions.
Though his aim was to vindicate Boeotia, [Pindar] has probably done her a disservice, in that he has helped to immortalise the scurrilous proverb Βοιωτία ύς, which he wished to confute. ... If left to itself, the slander might have passed into oblivion long ago. [W. Rhys Roberts, "The Ancient Boeotians," 1895]
main line (n.): "principal line of a railway," 1841; meaning "affluent area of residence" is by 1917, originally (with capitals) that of Philadelphia, from the "main line" of the Pennsylvania Railroad which added local stops to a string of backwater towns west of the city late 19c. that helped turn them into fashionable suburbs.
The Main Line, Philadelphia's most famous suburban district, was deliberately conceived in the 1870's and 1880's by the [Pennsylvania] Railroad, which built high-toned housing developments, ran hotels, more or less forced its executives to plunk their estates out there, and created a whole series of somewhat spurious Welsh towns along the railroad tracks. ... Now everybody assumes these all date from 1682, like the Robertses; but as Chestnut Hill people like to say, "nobody but Welsh peasants lived on the Main Line till the Railroad built it up." [Nathaniel Burt, "The Perennial Philadelphians," 1963]
The original station stops were, in order out from the city, Overbrook, Merion, Narberth, Wynnewood, Ardmore, Haverford, Bryn Mawr, Paoli. The train line for commuters along it is the Paoli Local.
medicine (n.): c. 1200, "medical treatment, cure, remedy," also used figuratively, of spiritual remedies, from Old French medecine (Modern French médicine) "medicine, art of healing, cure, treatment, potion," from Latin medicina "the healing art, medicine; a remedy," also used figuratively, perhaps originally ars medicina "the medical art," from fem. of medicinus (adj.) "of a doctor," from medicus "a physician" (see medical); though OED finds evidence for this is wanting. Meaning "a medicinal potion or plaster" in English is mid-14c.

To take (one's) medicine "submit to something disagreeable" is first recorded 1865. North American Indian medicine-man "shaman" is first attested 1801, from American Indian adoption of the word medicine in sense of "magical influence." The U.S.-Canadian boundary they called Medicine Line (first attested 1910), because it conferred a kind of magic protection: punishment for crimes committed on one side of it could be avoided by crossing over to the other. Medicine show "traveling show meant to attract a crowd so patent medicine can be sold to them" is American English, 1938. Medicine ball "stuffed leather ball used for exercise" is from 1889.
It is called a "medicine ball" and it got that title from Prof. Roberts, now of Springfield, whose fame is widespread, and whose bright and peculiar dictionary of terms for his prescription department in physical culture is taught in every first-class conducted Y.M.C.A. gymnasium in America. Prof. Roberts calls it a "medicine ball" because playful exercise with it invigorates the body, promotes digestion, and restores and preserves one's health. ["Scientific American Supplement," March 16, 1889]
ribosome (n.): 1958, coined by U.S. microbiologist Richard B. Roberts (1910-1980) from ribo(nucleic acid) + -some "body."
spoof (n.): "hoax, deception," 1889, from spouf (1884), name of a game invented by British comedian Arthur Roberts (1852-1933). Sense of "a parody, satirical skit or play" is first recorded 1958, from verb in this sense (1914).
