Online Etymology Dictionary

imbecility (n.): early 15c., "physical weakness, feebleness (of a body part), impotence," from Middle French imbécillité and directly from Latin imbecillitatem (nominative imbecillitas) "weakness, feebleness, helplessness," from imbecillus "weak, feeble," of uncertain origin. "Weakness in mind" (as opposed to body) was a secondary sense in Latin but was not attested in English until 1620s.

The Latin word traditionally is said to mean "unsupported" or "without a walking stick" (Isidore: quasi sine baculo), from assimilated form of in- "not, opposite of" (see in- (1)) + baculum "a stick" (see bacillus), but Century Dictionary finds that "improbable" and de Vaan adds "it seems to me that exactly the persons who can walk without a support are the stronger ones."
impertinent (adj.): late 14c., "unconnected, unrelated, not to the point" (now obsolete; OED's last citation is from Coleridge), from Old French impertinent (14c.) or directly from Late Latin impertinentem (nominative impertinens) "not belonging," literally "not to the point," from assimilated form of Latin in- "not, opposite of" (see in- (1)) + pertinens (see pertinent). Sense of "rudely bold, uncivil, offensively presumptuous" is from 1680s, from earlier sense of "not appropriate to the situation" (1580s), which probably is modeled on similar use in French, especially by Molière, from notion of meddling in what is beyond one's proper sphere.
Impertinent means forward, intrusive, generally from curiosity but sometimes with undesired advice, etc.; officious means forward to offer and undertake service where it is neither needed nor desired. A busybody may be either impertinent or officious, or both. [Century Dictionary]
jackanapes (n.): mid-15c., "a monkey," also "an impertinent, conceited fellow, an absurd fop," a general term of reproach (in mid-15c. especially a contemptuous nickname for William de la Pole, Duke of Suffolk), of unknown origin. Apparently from Jack of Naples, but whether this is some specific personification of Jack (which is attested from 16c. as "saucy or impertinent fellow") or folk etymology of jack (n.) + ape (n.) is unknown. See extensive note in OED. Century Dictionary suggests "orig., it is supposed, a man who exhibited performing apes." Farmer & Henley say "originally, no doubt, a gaudy-suited and performing ape." Its fem. counterpart is Jane-of-apes (Massinger) "a pert, forward girl."
Occam's razor: when two competing hypotheses explain the data equally well, choose the simpler. Or, as Sir William Hamilton puts it, "Neither more, nor more onerous, causes are to be assumed, than are necessary to account for the phenomena." Named for English philosopher William of Ockham or Occam (c. 1285-c. 1349), who expressed it with Entia non sunt multiplicanda praeter ncccssitatem.
So called after William of Occam (died about 1349): but, as a historical fact, Occam does not make much use of this principle, which belongs rather to the contemporary nominalist William Durand de St. Pourçain (died 1332). [Century Dictionary]
vacuum (n.): 1540s, "emptiness of space," from Latin vacuum "an empty space, vacant place, a void," noun use of neuter of vacuus "empty, unoccupied, devoid of," figuratively "free, unoccupied," related to vacare "be empty" (see vain). Properly a loan-translation of Greek kenon, literally "that which is empty." Meaning "a space emptied of air" is attested from 1650s. Vacuum tube "glass thermionic device" is attested from 1859. Vacuum cleaner is from 1903; shortened form vacuum (n.) first recorded 1910.
The metaphysicians of Elea, Parmenides and Melissus, started the notion that a vacuum was impossible, and this became a favorite doctrine with Aristotle. All the scholastics upheld the maxim that "nature abhors a vacuum." [Century Dictionary]
tangle (v.): mid-14c., nasalized variant of tagilen "to involve in a difficult situation, entangle," from a Scandinavian source (compare dialectal Swedish taggla "to disorder," Old Norse þongull "seaweed"), from Proto-Germanic *thangul- (source also of Frisian tung, Dutch tang, German Tang "seaweed"); thus the original sense of the root evidently was "seaweed" as something that entangles (itself, or oars, or fishes, or nets). "The development of such a verb from a noun of limited use like tangle 1 is somewhat remarkable, and needs confirmation" [Century Dictionary]. In reference to material things, from c. 1500. Meaning "to fight with" is American English, first recorded 1928. Related: Tangled; tangling. Tanglefoot (1859) was Western American English slang for "strong whiskey."
quarterstaff (n.): also quarter-staff, 1540s (quarter-stroke "stroke with a quarterstaff" is attested from early 15c.), stout pole, six to eight feet long (six-and-a-half sometimes is given as the standard length), tipped with iron, formerly a weapon used by the English peasantry. From staff (n.); the quarter is of uncertain signification. According to one theory, favored by fencing manuals, etc., it likely is in reference to operation of the weapon:
It was grasped by one hand in the middle, and by the other between the middle and the end. In the attack the latter hand shifted from one quarter of the staff to the other, giving the weapon a rapid circular motion, which brought the ends on the adversary at unexpected points. [Century Dictionary]
Linguists tend to prefer an explanation from woodcutting, perhaps a reference to a cut of lumber known as a quarter, but contemporary evidence is wanting for either conjecture.
tabby (n.): 1630s, "striped silk taffeta," from French tabis "a rich, watered silk" (originally striped), from Middle French atabis (14c.), from Arabic 'attabi, from 'Attabiyah, a neighborhood of Baghdad where such cloth was made, said to be named for prince 'Attab of the Omayyad dynasty. As an adjective from 1630s.

Tabby cat, one with a striped coat, is attested from 1690s; shortened form tabby first attested 1774. "The wild original of the domestic cat is always of such coloration" [Century Dictionary]. Sense of "female cat" (1826) may be influenced by the fem. proper name Tabby, a pet form of Tabitha, which was used in late 18c. as slang for "spiteful spinster, difficult old woman."
josh (v.): "to make fun of, to banter," 1845 (intransitive), 1852 (transitive), American English; according to "Dictionary of American Slang," the earliest example is capitalized, hence it is probably from the familiar version of the proper name Joshua. Perhaps it was taken as a typical name of an old farmer.

If those dates are correct, the word was in use earlier than the career of U.S. humorist Josh Billings, pseudonym of Henry Wheeler Shaw (1818-1885), who did not begin to write and lecture until 1860; but his popularity after 1869 may have influence that of the word, or even re-coined it, as it does not seem to have been much in print before 1875.
About the most originality that any writer can hope to achieve honestly is to steal with good judgment. ["Josh Billings"]
Related: Joshed; joshing.
hedge (n.): Old English hecg "hedge," originally any fence, living or artificial, from West Germanic *hagjo (source also of Middle Dutch hegge, Dutch heg, Old High German hegga, German Hecke "hedge"), from PIE root *kagh- "to catch, seize; wickerwork, fence" (source also of Latin caulae "a sheepfold, enclosure," Gaulish caio "circumvallation," Welsh cae "fence, hedge"). Related to Old English haga "enclosure, hedge" (see haw (n.)).

Figurative sense of "boundary, barrier" is from mid-14c. As hedges were "often used by vagabonds as places of shelter or resort" [Century Dictionary], the word, compounded, "notes something mean, vile, of the lowest class" [Johnson], from contemptuous attributive sense of "plying one's trade under a hedge" (hedge-priest, hedge-lawyer, hedge-wench, etc.), a usage attested from 1530s. The noun in the betting sense is from 1736 (see hedge (v.)).
inauguration (n.): 1560s, from French inauguration "installation, consecration," and directly from Late Latin inaugurationem (nominative inauguratio) "consecration," presumably originally "installment under good omens;" noun of action from past participle stem of inaugurare "take omens from the flight of birds; consecrate or install when omens are favorable," from in- "on, in" (see in- (2)) + augurare "to act as an augur, predict" (see augur (n.)).
INAUGURATIO was in general the ceremony by which the augurs obtained, or endeavoured to obtain, the sanction of the gods to something which had been decreed by man; in particular, however, it was the ceremony by which things or persons were consecrated to the gods .... If the signs observed by the inaugurating priest were thought favourable, the decree of men had the sanction of the gods, and the inauguratio was completed. [William Smith (ed.), "Dictionary of Greek and Roman Antiquities," 1842]
malkin (n.): also mawkin, "a slattern; woman of the lower classes," late 13c., from fem. proper name Malkyn, a diminutive of Mault "Maud" (see Matilda). Also attested from c. 1200 as the proper name of a female specter. Sense of "untidy woman" led to meaning "mop, bundle of rags on a stick" (used to clean ovens, artillery pieces, etc.), c. 1400.
MALKINTRASH. One in dismal garb. [Grose, "Classical Dictionary of the Vulgar Tongue," London, 1785]
Attested as the name of a cat since 1670s (perhaps earlier as Grimalkin, 16c.); compare Serbo-Croatian mačka "cat," originally a pet-name form of Maria. Also used in Scotland and northern England as the name of a hare (1724).
elegant (adj.): late 15c., "tastefully ornate," from Middle French élégant (15c.), from Latin elegantem (nominative elegans) "choice, fine, tasteful," collateral form of present participle of eligere "select with care, choose." Meaning "characterized by refined grace" is from 1520s. Latin elegans originally was a term of reproach, "dainty, fastidious;" the notion of "tastefully refined" emerged in classical Latin. Related: Elegantly.
Elegant implies that anything of an artificial character to which it is applied is the result of training and cultivation through the study of models or ideals of grace; graceful implies less of consciousness, and suggests often a natural gift. A rustic, uneducated girl may be naturally graceful, but not elegant. [Century Dictionary]
bastard (n.): "illegitimate child," early 13c., from Old French bastard (11c., Modern French bâtard), "acknowledged child of a nobleman by a woman other than his wife," probably from fils de bast "packsaddle son," meaning a child conceived on an improvised bed (saddles often doubled as beds while traveling), with pejorative ending -art (see -ard). Alternative possibly is that the word is from Proto-Germanic *banstiz "barn," equally suggestive of low origin.

Not always regarded as a stigma; the Conqueror is referred to in state documents as "William the Bastard." Figurative sense of "something not pure or genuine" is late 14c.; use as a vulgar term of abuse for a man is attested from 1830. As an adjective from late 14c. Among the "bastard" words in Halliwell-Phillipps' "Dictionary of Archaic and Provincial Words" are avetrol, chance-bairn, by-blow, harecoppe, horcop, and gimbo ("a bastard's bastard").
waive (v.): c. 1300, "deprive of legal protection," from Anglo-French weyver "to abandon, waive" (Old French guever "to abandon, give back"), probably from a Scandinavian source akin to Old Norse veifa "to swing about," from Proto-Germanic *waif- (see waif). In Middle English legal language, used of rights, goods, or women.
If the defendant be a woman, the proceeding is called a waiver; for as women were not sworn to the law by taking the oath of allegiance in the leet (as men anciently were when of the age of twelve years and upwards), they could not properly be outlawed, but were said to be waived, i.e., derelicta, left out, or not regarded. [from section subtitled "Outlawry" in J.J.S. Wharton, "Law-Lexicon, or Dictionary of Jurisprudence," London, 1867]
Related: Waived; waiving.
fence (n.): early 14c., "action of defending, resistance; means of protection, fortification," shortening of defens (see defense). The same pattern also yielded fend, fender; and obsolete fensive "defensive" (late 16c.). Spelling alternated between -c- and -s- in Middle English. Sense of "enclosure" is first recorded mid-15c. on notion of "that which serves as a defense." Sense of "dealer in stolen goods" is thieves' slang, first attested c. 1700, from notion of such transactions taking place under defense of secrecy.

To be figuratively on the fence "uncommitted" is from 1828, perhaps from the notion of spectators at a fight, or a simple literal image: "A man sitting on the top of a fence, can jump down on either side with equal facility." [Bartlett, "Dictionary of Americanisms," 1848].
aegis (n.): "protection," 1793, from Latin aegis, from Greek Aigis, the name of the shield of Zeus, said by Herodotus to be related to aix (genitive aigos) "goat," from PIE *aig- "goat" (source also of Sanskrit ajah, Lithuanian ozys "he-goat"), as the shield was of goatskin. Athene's aigis was a short goat-skin cloak, covered with scales, set with a gorgon's head, and fringed with snakes. The exact use and purpose of it is not now clear.
The goatskin would be worn with the two forelegs tied in front of the wearer's breast, or possibly with the head passed through an opening made at the neck, by the removal of the animal's head. [F. Warre Cornish, ed., "Dictionary of Greek and Roman Antiquities," London, 1898]
viaduct (n.): 1816, from Latin via "road" (see via) + -duct as in aqueduct. French viaduc is a 19c. English loan-word.
An extensive bridge consisting, strictly of a series of arches of masonry, erected for the purpose of conducting a road or a railway a valley or a district of low level, or over existing channels of communication, where an embankment would be impracticable or inexpedient; more widely, any elevated roadway which artificial constructions of timber, iron, bricks, or stonework are established. [Century Dictionary]
But the word apparently was coined by English landscape gardener Humphry Repton (1752-1818) for an architectural feature, "a form of bridge adapted to the purposes of passing over, which may unite strength with grace, or use with beauty ...."
opera (n.): "a drama sung" [Klein], 1640s, from Italian opera, literally "a work, labor, composition," from Latin opera "work, effort" (Latin plural regarded as feminine singular), secondary (abstract) noun from operari "to work," from opus (genitive operis) "a work" (see opus). Defined in "Elson's Music Dictionary" as, "a form of musical composition evolved shortly before 1600, by some enthusiastic Florentine amateurs who sought to bring back the Greek plays to the modern stage."
No good opera plot can be sensible. ... People do not sing when they are feeling sensible. [W.H. Auden, 1961]
As a branch of dramatic art, it is attested from 1759. First record of opera glass "small binoculars for use at the theater" is from 1738. Soap opera is first recorded 1939, as a disparaging reference to daytime radio dramas sponsored by soap manufacturers.
taxi (n.): 1907, shortening of taximeter cab (introduced in London in March 1907), from taximeter "automatic meter to record the distance and fare" (1898), from French taximètre, from German Taxameter (1890), coined from Medieval Latin taxa "tax, charge."

An earlier English form was taxameter (1894), used in horse-drawn cabs. Taxi dancer "woman whose services may be hired at a dance hall" is recorded from 1930. Taxi squad in U.S. football is 1966, said to be from a former Cleveland Browns owner who gave his reserves jobs with his taxicab company to keep them paid and available ["Dictionary of American Slang"], but other explanations ("short-term hire" or "shuttling back and forth" from the main team) seem possible.
whistle (v.): Old English hwistlian "to whistle," from Proto-Germanic *hwis-, of imitative origin (source also of Old Norse hvisla "to whisper," Danish hvisle "to hiss;" see whisper (v.)). Used also in Middle English of the hissing of serpents; in 17c. it also could mean "whisper." Transitive use from late 15c. Related: Whistled; whistling. At public events, often an expression of support or encouragement in U.S., but often derisive in Britain. To whistle for (with small prospect of getting) is perhaps from nautical whistling for a wind, an old sailor's superstition during a calm. "Such men will not whistle during a storm" [Century Dictionary]. To whistle "Dixie" is from 1940.
center (n.): late 14c., "middle point of a circle; point round which something revolves," from Old French centre (14c.), from Latin centrum "center," originally fixed point of the two points of a drafting compass, from Greek kentron "sharp point, goad, sting of a wasp," from kentein "stitch," from PIE root *kent- "to prick" (source also of Breton kentr "a spur," Welsh cethr "nail," Old High German hantag "sharp, pointed").

Figuratively from 1680s. Meaning "the middle of anything" attested from 1590s. Spelling with -re popularized in Britain by Johnson's dictionary (following Bailey's), though -er is older and was used by Shakespeare, Milton, and Pope. Center of gravity is recorded from 1650s. Center of attention is from 1868.
chaparral (n.): "shrub thicket," 1850, American English, from Spanish chaparro "evergreen oak," perhaps from Basque txapar "little thicket," diminutive of sapar "heath, thicket."
In Spain, a chaparral is a bush of a species of oak. The termination al signifies a place abounding in; as, chaparral, a place of oak-bushes, almendral, an almond orchard; parral, a vineyard; cafetal, a coffee plantation, etc., etc.

This word, chaparral, has been introduced into the language since our acquisition of Texas and New Mexico, where these bushes abound. It is a series of thickets, of various sizes, from one hundred yards to a mile through, with bushes and briars, all covered with thorns, and so closely entwined together as almost to prevent the passage of any thing larger than a wolf or hare. [John Russell Bartlett, "Dictionary of Americanisms," 1859]
instinct (n.): early 15c., "a prompting" (a sense now obsolete), from Old French instinct (14c.) or directly from Latin instinctus "instigation, impulse, inspiration," noun use of past participle of instinguere "to incite, impel," from in- "into, in, on, upon" (see in- (2)) + stinguere "prick, goad," from PIE *steig- "to prick, stick, pierce" (see stick (v.)).

Meaning "animal faculty of intuitive perception" is from mid-15c., from notion of "natural prompting." General sense of "natural tendency" is first recorded 1560s.
Instinct is said to be blind--that is, either the end is not consciously recognized by the animal, or the connection of the means with the end is not understood. Instinct is also, in general, somewhat deficient in instant adaptability to extraordinary circumstances. [Century Dictionary]
instruction (n.): c. 1400, instruccioun, "action or process of teaching," from Old French instruccion (14c., Modern French instruction), from Latin instructionem (nominative instructio) "an array, arrangement," in Late Latin "teaching," from past participle stem of instruere "arrange, prepare, set in order; inform, teach," from in- "on" (see in- (2)) + struere "to pile, build" (see structure (n.)).
Teaching is the general word for the imparting of knowledge .... Instruction has the imparting of knowledge for its object, but emphasizes, more than teaching, the employment of orderly arrangement in the things taught. [Century Dictionary]
Meaning "an authoritative direction telling someone what to do; a document giving such directions," is early 15c. Related: Instructions.
flavor (n.): c. 1300, "a smell, odor" (usually a pleasing one), from Old French flaor "smell, odor; action of smelling, sense of smell," probably from Vulgar Latin flator "odor," literally "that which blows," in classical Latin "blower," from flare "to blow, puff," which is cognate with Old English blawan (see blow (v.1)).

"Not common before Milton's time" [Century Dictionary], and it is not clear what exactly Milton meant when he used it. The same Vulgar Latin source produced Old Italian fiatore "a bad odor." Sense of "taste, savor" is 1690s, perhaps 1670s; originally "the element in taste which depends on the sense of smell." The -v- in the English word is euphonic or perhaps from influence of savor. Flavor-of-the-month is from 1946 (originally of ice cream).
flip-flop (n.): also flip flop, "plastic thong beach sandal," by 1970, imitative of the sound of walking in them. Flip-flap had been used in various senses, mostly echoic or imitative of a kind of loose flapping movement, since 1520s:
Flip-flaps, a peculiar rollicking dance indulged in by costermongers, better described as the double shuffle; originally a kind of somersault. [Hotten's Slang Dictionary, 1864]
Flip-flop in the general sense of "complete reversal of direction" dates from 1900; it began to be used in electronics in the 1930s in reference to switching circuits that alternate between two states. As a verb by 1897. Flop (n.) in the sense "a turn-round, especially in politics" is from 1880.
height (n.): Old English hiehþu, Anglian hehþo "highest part or point, summit; the heavens, heaven," from root of heah "high" (see high) + -itha, Germanic abstract noun suffix (as in width, depth; see -th (2)). Compare Old Norse hæð, Middle Dutch hoochte, Old High German hohida, Gothic hauhiþa "height." Meaning "distance from bottom to top" is from late 13c. Meaning "excellence, high degree of a quality" is late 14c. Century Dictionary says "there is no reason for the distinction of vowel between high and height. The modern pronunciation with -t emerged 13c. but wasn't established until 19c.; Milton used highth and heighth is still colloquial in English. Compare Dutch hoogte, Danish hjöde.
flora (n.): c. 1500, "Roman goddess of flowers;" 1777, "the plant life of a region or epoch," from Latin Flora, "goddess of flowers," from flos (accusative florem, genitive floris) "flower," from *flo-s-, Italic suffixed form of PIE *bhle- "to blossom, flourish" (source also of Middle Irish blath, Welsh blawd "blossom, flower," Old English blowan "to flower, bloom"), extended form of *bhel- (3) "to thrive, bloom," which is possibly identical with or derived from *bhel- (2) "to blow, swell" (see bole).

Her festival, the Floralia, was April 28 to May 2 and featured "comic theatrical representations" and "excessive drinking" [Century Dictionary]. The French Revolutionary calendar had a month Floréal (April 20-May 20). Used as the title of systematically descriptive plant catalogues since 1640s, but popularized by Linnaeus in his landmark 1745 study of Swedish plants, "Flora Suecica."
globe (n.): late 14c., "a large mass;" mid-15c., "spherical solid body, a sphere," from Middle French globe (14c.) and directly from Latin globus "round mass, sphere, ball" (also, of men, "a throng, crowd, body, mass"), which is related to gleba "clod, lump of soil" (see glebe) and perhaps glomus "a ball, ball of yarn," but de Vaan says the last two probably are non-IE loan-words. Sense of "the planet earth," also "map of the earth or sky drawn on the surface of an artificial sphere" are attested from 1550s. Meaning "globe-shaped glass vessel" is from 1660s. "A globe is often solid, a sphere often hollow. The secondary senses of globe are physical; those of sphere are moral." [Century Dictionary"].
hi (interj.): exclamation of greeting, 1862, American English (first recorded reference is to speech of a Kansas Indian), originally to attract attention (15c.), probably a variant of Middle English hy, hey (late 15c.) which also was an exclamation to call attention. The only definition in the "Century Dictionary" [1902] is "An exclamation of surprise, admiration, etc.: often used ironically and in derision," suggesting the development as a greeting-word mostly took place early 20c.
Even more informal is the widely used 'Hi.' A friendly greeting for people who already know each other, it should never be said in answer to a formal introduction, but it is universally used, and accepted, by the young. ["The New Emily Post's Etiquette," 1922]
Extended form hiya attested from 1940.
territory (n.): late 14c., "land under the jurisdiction of a town, state, etc.," probably from Latin territorium "land around a town, domain, district," from terra "earth, land" (see terrain) + -orium, suffix denoting place (see -ory). Sense of "any tract of land, district, region" is first attested c. 1600. Specific U.S. sense of "organized self-governing region not yet a state" is from 1799. Of regions defended by animals from 1774.

"Since -torium is a productive suffix only after verbal stems, the rise of terri-torium is unexplained" [Michiel de Vaan, "Etymological Dictionary of Latin and the other Italic Languages"]. An alternative theory, somewhat supported by the vowels of the original Latin word, suggests derivation from terrere "to frighten" (see terrible); thus territorium would mean "a place from which people are warned off."
nutmeg (n.): "hard aromatic seed of the East Indies," c. 1300, from Old North French or Anglo-French *noiz mugue, from Old French nois muguete, unexplained alteration of nois muscade "nut smelling like musk," from nois "nut" (from Latin nux) + Latin muscada, fem. of muscat "musky" (see muscat). Probably influenced in English by Medieval Latin nux maga (compare unaltered Dutch muskaatnoot, German muscatnuß, Swedish muskotnöt).

American English colloquial wooden nutmeg "anything false or fraudulent" is from 1830. Connecticut is called the Nutmeg State "in allusion to the story that wooden nutmegs are there manufactured for exportation." [John Russell Bartlett, "Dictionary of Americanisms," 1859]
patience (n.): c. 1200, "quality of being willing to bear adversities, calm endurance of misfortune, suffering, etc.," from Old French pacience "patience; sufferance, permission" (12c.) and directly from Latin patientia "patience, endurance, submission," also "indulgence, leniency; humility; submissiveness; submission to lust;" literally "quality of suffering." It is an abstract noun formed from the adjective patientem (nominative patiens) "bearing, supporting; suffering, enduring, permitting; tolerant," but also "firm, unyielding, hard," used of persons as well as of navigable rivers, present participle of pati "to suffer, endure," from PIE root *pe(i)- "to damage, injure, hurt" (see passion).
Patience, n. A minor form of despair, disguised as a virtue. [Ambrose Bierce, "Devil's Dictionary," 1911]
Meaning "constancy in effort" is attested from 1510s. Meaning "card game for one person" is from 1816.
bitch (n.): Old English bicce "female dog," probably from Old Norse bikkjuna "female of the dog" (also fox, wolf, and occasionally other beasts), which is of unknown origin. Grimm derives the Old Norse word from Lapp pittja, but OED notes that "the converse is equally possible." As a term of contempt applied to women, it dates from c. 1400; of a man, c. 1500, playfully, in the sense of "dog." Used among male homosexuals from 1930s. In modern (1990s, originally African-American vernacular) slang, its use with reference to a man is sexually contemptuous, from the "woman" insult.
BITCH. A she dog, or doggess; the most offensive appellation that can be given to an English woman, even more provoking than that of whore. ["Dictionary of the Vulgar Tongue," 1811]
Bitch goddess coined 1906 by William James; the original one was success.
ambulance (n.): 1798, "mobile or field hospital," from French (hôpital) ambulant, literally "walking (hospital)," from Latin ambulantem (nominative ambulans), present participle of ambulare "to walk" (see amble).
AMBULANCE, s. f. a moveable hospital. These were houses constructed in a manner so as to be taken to pieces, and carried from place to place, according to the movements of the army; and served as receptacles in which the sick and wounded men might be received and attended. ["Lexicographica-Neologica Gallica" (The Neological French Dictionary), William Dupré, London, 1801]
The word was not common in English until the meaning transferred from "field hospital" to "vehicle for conveying wounded from field" (1854) during the Crimean War. In late 19c. U.S. the word was used dialectally to mean "prairie wagon." Ambulance-chaser as a contemptuous term for a type of lawyer dates from 1897.
escutcheon (n.): "shield on which a coat of arms is depicted," late 15c., from Old North French escuchon, variant of Old French escusson "half-crown (coin); coat of arms, heraldic escutcheon," from Vulgar Latin *scutionem, from Latin scutum "shield" (see hide (n.1)).
Escutcheon of pretense, in her., a small escutcheon charged upon the main escutcheon, indicating the wearer's pretensions to some distinction, or to an estate, armorial bearings, etc., which are not his by strict right of descent. It is especially used to denote the marriage of the bearer to an heiress whose arms it bears. Also called inescutcheon. [Century Dictionary]

Clev. Without doubt: he is a Knight? Jord. Yes Sir.
Clev. He is a Fool too?
Jord. A little shallow[,] my Brother writes me word, but that is a blot in many a Knights Escutcheon.
[Edward Ravenscroft, "Mamamouchi, or the Citizen Turn'd Gentleman," 1675]
chowder (n.): 1751, American English, apparently named for the pot it was cooked in: French chaudière "a pot" (12c.), from Late Latin caldaria (see caldron). The word and the practice introduced in Newfoundland by Breton fishermen, and spreading thence to New England.
CHOWDER. A favorite dish in New England, made of fish, pork, onions, and biscuit stewed together. Cider and champagne are sometimes added. Pic-nic parties to the sea-shore generally have a dish of chowder, prepared by themselves in some grove near the beach, from fish caught at the same time. [John Russell Bartlett, "Dictionary of Americanisms," 1859]
The derogatory chowderhead (1819) is a corruption of cholter-head (16c.), from jolthead, which is of unknown origin.
Hindu (n.): 1660s, from Persian Hindu (adjective and noun) "Indian," from Hind "India," from Sanskrit sindhu "river," meaning here the Indus; hence "region of the Indus," the sense then gradually was extended by invading peoples to encompass all northern India. "Properly, one of the native race in India descended from the Aryan conquerors. ... More loosely, the name includes also the non-Aryan inhabitants of India" [Century Dictionary, 1902]. As an adjective from 1690s. The Hindu Kush mountain range is said to mean literally "Indian killer," and was said to have been the name given by the Persians to a pass where their Indian slaves had perished in winter, but this likely is folk etymology.
forsake (v.): Old English forsacan "object to, oppose, refuse, deny; give up, renounce" (past tense forsoc, past participle forsacen), from for- "completely" + sacan "to struggle, dispute, wrangle; accuse, blame" (see sake). Related: Forsaking. Similar formation in Old Saxon farsakan, Dutch verzaken, Old High German farsahhan "deny, repudiate," Danish forsage "give up, refuse."
Forsake is chiefly applied to leaving that by which natural affection or a sense of duty should or might have led us to remain: as, to forsake one's home, friends, country, or cause; a bird forsakes its nest. In the passive it often means left desolate, forlorn. [Century Dictionary]
Iran: country name, from Persian Iran, from Middle Persian Ērān "(land) of the Iranians," genitive plural of ēr- "an Iranian," from Old Iranian *arya- (Old Persian ariya-, Avestan airya-) "Iranian", from Indo-Iranian *arya- or *ārya-, a self-designation, perhaps meaning "compatriot" (see Aryan).

In English it began to be used 1760s, by orientalists and linguists (Alexander Dow, William Jones), in historical contexts, and usually with a footnote identifying it with modern Persia; as recently as 1903 "Century Dictionary" defined it as "the ancient name of the region lying between Kurdistan and India." In 1935 the government of Reza Shah Pahlavi requested governments with which it had diplomatic relations to call his country Iran, after the indigenous name, rather than the Greek-derived Persia.
irk (v.): early 15c., irken, "to trouble (someone), disturb, hinder, annoy;" earlier "be lax, slow, or unwilling (in doing something); be displeased or discontented" (early 14c.); "be weary of, be disgusted with" (c. 1400); of uncertain origin.

Watkins suggests it is related to Old Norse yrkja "work." Middle High German erken "to disgust" also has been suggested. A Middle English adjective, irk, meaning "weary, tired, bored; distressed, troubled; troublesome, annoying," is attested from c. 1300 in Northern and Midlands writing; it is sometimes said to be from the verb, but it is older, and "Middle English Dictionary" says this is probably Celtic, and compares Old Irish arcoat "he injures," erchoat "harm, injury."
irregular (adj.): late 14c., "not in conformity with Church rules," from Old French irreguler "irregular, incapable, incompetent" (13c., Modern French irrégulier), from Medieval Latin irregularis "not regular," from assimilated form of in- "not, opposite of" (see in- (1)) + Latin regularis "having rules" (see regular (adj.)). General sense of "not conforming to regular rules or principles" is from late 15c. "It expresses the fact of being out of conformity with rule, but implies nothing more with certainty. Yet the word is sometimes used in a sinister sense, as though it were a euphemism for something worse." [Century Dictionary] Meaning "unsymmetrical" is from 1580s. In reference to variable stars, from 1797.
island (n.): 1590s, earlier yland (c. 1300), from Old English igland, iegland "an island," from ieg "island" (from Proto-Germanic *aujo "thing on the water," from PIE *akwa- "water;" see aqua-) + land (n.). As an adjective from 1620s.

Spelling modified 15c.-16c. by association with similar but unrelated isle. Similar formation in Old Frisian eiland, Middle Dutch eyland, German Eiland, Danish öland, etc. In place names, Old English ieg is often used of "slightly raised dry ground offering settlement sites in areas surrounded by marsh or subject to flooding" [Cambridge Dictionary of English Place-Names]. Island universe "solar system" (1846) translates German Weltinsel (von Humboldt, 1845). An Old English cognate was ealand "river-land, watered place, meadow by a river." Related: Islander.
holm (n.): "small island in a river; river meadow," late Old English, from Old Norse holmr "small island," especially in a river or bay, or cognate Old Danish hulm, from Proto-Germanic *hul-maz, from PIE root *kel- (4) "to rise, be elevated, be prominent; hill" (see hill (n.)). Obsolete, but preserved in place names, where it has various senses derived from the basic one of "island:" "'raised ground in marsh, enclosure of marginal land, land in a river-bend, river meadow, promontory'" ["Cambridge Dictionary of English Place-Names"]. Cognate Old English holm (only attested in poetic language) meant "sea, ocean, wave."
loo (n.2): type of card game, 1670s, short for lanterloo (1660s), from French lanturelu, originally (1620s) the refrain of a popular comic song; according to French sources the refrain expresses a mocking refusal or an evasive answer and was formed on the older word for a type of song chorus, turelure; apparently a jingling reduplication of loure "bagpipe" (perhaps from Latin lura "bag, purse").
From its primary signification -- a kind of bagpipe inflated from the mouth -- the word 'loure' came to mean an old dance, in slower rhythm than the gigue, generally in 6-4 time. As this was danced to the nasal tones of the 'loure,' the term 'loure' was gradually applied to any passage meant to be played in the style of the old bagpipe airs. ["Grove's Dictionary of Music and Musicians," London, 1906]
The refrain sometimes is met in English as turra-lurra.
fungo (n.): "A fly ball hit to a player during fielding practice in which the batter (often a coach) tosses the ball into the air and hits it as it descends with a long and narrow bat." [Paul Dickson, "The Dickson Baseball Dictionary," 3rd ed., 2009], attested from 1867 (fungoes), baseball slang, of unknown origin; see Dickson's book for a listing of the guesses. Perhaps from a Scottish fung "to pitch, toss, fling;" perhaps from some dialectal fonge "catch," a relic of Old English fon "seize" (see fang), or possibly from the German cognate fangen. Not in OED 2nd ed. (1989). There does not seem to have been a noun phrase (a) fun go in use at the time. It formally resembles the Spanish and Italian words for "fungus."
cloister (n.): early 13c., from Old French cloistre "monastery, convent; enclosure" (12c., Modern French cloître), from Medieval Latin claustrum "portion of monastery closed off to laity," from Latin claustrum (usually in plural, claustra) "place shut in, enclosure; bar, bolt, means of shutting in," from past participle stem of claudere (see close (v.)).

"The original purpose of cloisters was to afford a place in which the monks could take exercise and recreation" [Century Dictionary]. Spelling in French influenced by cloison "partition." Old English had clustor, clauster in the sense "prison, lock, barrier," directly from Latin, and compare, from the same source, Dutch klooster, German Kloster, Polish klasztor.
Hoosier: "native or resident of Indiana," by c. 1830, American English, of unknown origin; newspapers in the 1830s published fanciful explanations, some still repeated, "none authenticated by evidence" [Century Dictionary]. Said to have been first printed Jan. 1, 1833, in the "Indianapolis Journal," in a poem, "The Hoosiers Nest," by John Finely, which poem was said to have been written in 1830 ["The Word Hoosier," "Indiana Historical Society Publications," vol. IV, No. 2, 1907], and to have been in oral use from late 1820s. Seemingly it originated among Ohio River boatmen; perhaps related to English dialectal (Cumberland) hoozer, used of anything unusually large [Barnhart]. For other theories, see the historical society article. The word also has been used generally for "country bumpkin."
down (n.2): Old English dun "down, moor; height, hill, mountain," from Proto-Germanic *dunaz- (source also of Middle Dutch dunen "sandy hill," Dutch duin), "probably a pre-insular loan-word from Celtic" [Cambridge Dictionary of English Place-Names], in other words, borrowed at a very early period, before the Anglo-Saxon migration, from PIE root *dheue- "to close, finish, come full circle." Meaning "elevated rolling grassland" is from c. 1300.

The non-English Germanic words tend to mean "dune, sand bank" (see dune), while the Celtic cognates tend to mean "hill, citadel" (compare Old Irish dun "hill, hill fort;" Welsh din "fortress, hill fort;" and second element in place names London, Verdun, etc.). German Düne, French dune, Italian, Spanish duna are said to be loan-words from Dutch.
