Hobbit (n.)youdaoicibaDictYouDict
1937, coined in the fantasy tales of J.R.R. Tolkien (1892-1973).
On a blank leaf I scrawled: 'In a hole in the ground there lived a hobbit.' I did not and do not know why. [Tolkien, letter to W.H. Auden, dated 1955]
The word also turns up in a very long list of folkloric supernatural creatures in the writings of Michael Aislabie Denham (d.1859), printed in volume 2 of "The Denham Tracts" [ed. James Hardy, London: Folklore Society, 1895], a compilation of Denham's scattered publications. Denham was an early folklorist who concentrated on Northumberland, Durham, Westmoreland, Cumberland, the Isle of Man, and Scotland.
What a happiness this must have been seventy or eighty years ago and upwards, to those chosen few who had the good luck to be born on the eve of this festival of all festivals; when the whole earth was so overrun with ghosts, boggles, bloody-bones, spirits, demons, ignis fatui, brownies, bugbears, black dogs, specters, shellycoats, scarecrows, witches, wizards, barguests, Robin-Goodfellows, hags, night-bats, scrags, breaknecks, fantasms, hobgoblins, hobhoulards, boggy-boes, dobbies, hob-thrusts, fetches, kelpies, warlocks, mock-beggars, mum-pokers, Jemmy-burties, urchins, satyrs, pans, fauns, sirens, tritons, centaurs, calcars, nymphs, imps, incubuses, spoorns, men-in-the-oak, hell-wains, fire-drakes, kit-a-can-sticks, Tom-tumblers, melch-dicks, larrs, kitty-witches, hobby-lanthorns, Dick-a-Tuesdays, Elf-fires, Gyl-burnt-tales, knockers, elves, rawheads, Meg-with-the-wads, old-shocks, ouphs, pad-foots, pixies, pictrees, giants, dwarfs, Tom-pokers, tutgots, snapdragons, sprets, spunks, conjurers, thurses, spurns, tantarrabobs, swaithes, tints, tod-lowries, Jack-in-the-Wads, mormos, changelings, redcaps, yeth-hounds, colt-pixies, Tom-thumbs, black-bugs, boggarts, scar-bugs, shag-foals, hodge-pochers, hob-thrushes, bugs, bull-beggars, bygorns, bolls, caddies, bomen, brags, wraiths, waffs, flay-boggarts, fiends, gallytrots, imps, gytrashes, patches, hob-and-lanthorns, gringes, boguests, bonelesses, Peg-powlers, pucks, fays, kidnappers, gallybeggars, hudskins, nickers, madcaps, trolls, robinets, friars' lanthorns, silkies, cauld-lads, death-hearses, goblins, hob-headlesses, bugaboos, kows, or cowes, nickies, nacks necks, waiths, miffies, buckies, ghouls, sylphs, guests, swarths, freiths, freits, gy-carlins Gyre-carling, pigmies, chittifaces, nixies, Jinny-burnt-tails, dudmen, hell-hounds, dopple-gangers, boggleboes, bogies, redmen, portunes, grants, hobbits, hobgoblins, brown-men, cowies, dunnies, wirrikows, alholdes, mannikins, follets, korreds, lubberkins, cluricauns, kobolds, leprechauns, kors, mares, korreds, puckles korigans, sylvans, succubuses, blackmen, shadows, banshees, lian-hanshees, clabbernappers, Gabriel-hounds, mawkins, doubles, corpse lights or candles, scrats, mahounds, trows, gnomes, sprites, fates, fiends, sibyls, nicknevins, whitewomen, fairies, thrummy-caps, cutties, and nisses, and apparitions of every shape, make, form, fashion, kind and description, that there was not a village in England that had not its own peculiar ghost. Nay, every lone tenement, castle, or mansion-house, which could boast of any antiquity had its bogle, its specter, or its knocker. The churches, churchyards, and crossroads were all haunted. Every green lane had its boulder-stone on which an apparition kept watch at night. Every common had its circle of fairies belonging to it. And there was scarcely a shepherd to be met with who had not seen a spirit!
[Emphasis added] It is curious that the name occurs nowhere else in folklore, and there is no evidence that Tolkien ever saw this. The word also was recorded from 1835 as "a term generally used in Wales to express a quantity made up of four Welsh pecks." Hobbitry attested from 1947.
hobble (v.)youdaoicibaDictYouDict
c. 1300, hoblen "to rock back and forth, toss up and down," probably related to its Dutch cognate hobbelen (which, however, is not recorded before late 15c.).

Meaning "to walk lamely" is from c. 1400. Transitive sense of "tie the legs (of an animal)" first recorded 1831, probably an alteration of 16c. hopple, cognate with Flemish hoppelen "to rock, jump," which also is related to Dutch hobbelen. Sense of "hamper, hinder" is c. 1870. Related: Hobbled; hobbling. The noun is 1727, from the verb.
hobbledehoy (n.)youdaoicibaDictYouDict
"clumsy or awkward youth," 1530s, of uncertain origin and the subject of much discussion. First element is probably hob in its sense of "clown, prankster" (see hobgoblin), the second element perhaps is Middle French de haye "worthless, untamed, wild," literally "of the hedge."
hobby (n.)youdaoicibaDictYouDict
late 13c., hobyn, "small horse, pony," later "mock horse used in the morris dance," and c. 1550 "child's toy riding horse," which led to hobby-horse in a transferred sense of "favorite pastime or avocation," first recorded 1670s, shortened to hobby by 1816. The connecting notion being "activity that doesn't go anywhere." Probably originally a proper name for a horse (see dobbin), a diminutive of Robert or Robin. The original hobbyhorse was a "Tourney Horse," a wooden or basketwork frame worn around the waist and held on with shoulder straps, with a fake tail and horse head attached, so the wearer appears to be riding a horse. These were part of church and civic celebrations at Midsummer and New Year's throughout England.
hobbyist (n.)youdaoicibaDictYouDict
1830, from hobby + -ist. Hobbyism is recorded from 1846.
hobgoblin (n.)youdaoicibaDictYouDict
1520s, from hob "elf," from Hobbe, a variant of Rob (compare Hick for Richard, Hodge for Rodger, etc.), short for Robin Goodfellow, elf character in German folklore, + goblin.
hobnail (n.)youdaoicibaDictYouDict
1590s, the first element probably identical with hob "rounded peg or pin used as a mark or target in games" (1580s), of unknown origin. See hob. Because they were used to make rough shoes, the word was used figuratively for "rustic person" 17c. and after. Related: Hobnailed.
hobnob (v.)youdaoicibaDictYouDict
1763, "to drink to each other," from hob and nob (1756) "to toast each other by turns, to buy alternate rounds of drinks," from c. 1550 hab nab "to have or have not, hit or miss," probably ultimately from Old English habban, nabban "have, not have," with the negative particle ne- attached, as was customary. Modern sense of "socialize" is 1866. Related: Hobnobbed; hobnobbing.
hobo (n.)youdaoicibaDictYouDict
1889, Western U.S., of unknown origin. Barnhart compares early 19c. English dialectal hawbuck "lout, clumsy fellow, country bumpkin." Or possibly from ho, boy, a workers' call on late 19c. western U.S. railroads. Facetious formation hobohemia, "community or life of hobos," is from 1923 (see bohemian).
HobokenyoudaoicibaDictYouDict
city in New Jersey, U.S., birthplace of Frank Sinatra, named by 17c. Dutch settlers for a village in modern Belgium that is now a suburb of Antwerp.
Hobson's choice (n.)youdaoicibaDictYouDict
English university slang term, supposedly a reference to Thomas Hobson (c. 1544-1631), Cambridge stable manager who let horses and gave customers a choice of the horse next in line or none at all. Phrase popularized c. 1660 by Milton, who was at Cambridge from 1625-29.
Hobson-JobsonyoudaoicibaDictYouDict
1690s, hossen gossen, said to have been British soldiers' mangled Englishing of the Arabic cry they heard at Muharram processions in India, Ya Hasan! Ya Husayn! ("O Hassan! O Husain!"), mourning two grandsons of the Prophet who died fighting for the faith. Title of Yule & Burnell's 1886 glossary of Anglo-Indian words, and taken by linguists in naming the law of Hobson-Jobson, describing the effort to bring a new and strange word into harmony with the language.
hocyoudaoicibaDictYouDict
Latin, literally "this."
hock (n.1)youdaoicibaDictYouDict
"joint in the hind leg of a horse," mid-15c., earlier hockshin (late 14c.), from Old English hohsinu "sinew of the heel, Achilles' tendon," literally "heel sinew," from hoh "heel," from Proto-Germanic *hanhaz (cognates: German Hachse "hock," Old English hæla "heel"), from PIE *kenk- (3) "heel, bend of the knee."
hock (n.2)youdaoicibaDictYouDict
"Rhenish wine," 1620s, shortening of Hockamore, from German Hochheimer, "(wine) of Hochheim," town on the Main where wine was made; sense extended to German white wines in general.
hock (n.3)youdaoicibaDictYouDict
"pawn, debt," 1859, American English, in hock, which meant both "in debt" and "in prison," from Dutch hok "jail, pen, doghouse, hutch, hovel." The verb is 1878, from the noun.
When one gambler is caught by another, smarter than himself, and is beat, then he is in hock. Men are only caught, or put in hock, on the race-tracks, or on the steamboats down South. ... Among thieves a man is in hock when he is in prison. [G.W. Matsell, "Vocabulum," 1859]
hockey (n.)youdaoicibaDictYouDict
after an isolated reference from Ireland dated 1527 ("The horlinge of the litill balle with hockie stickes or staves ..."), the word is next recorded 1838 from W. Sussex; of unknown origin, perhaps related to Middle French hoquet "shepherd's staff, crook," diminutive of Old French hoc "hook." The hooked clubs with which the game is played resemble shepherds' staves. In North America, ice hockey is distinguished from field hockey.
hocus-pocusyoudaoicibaDictYouDict
1620s, Hocas Pocas, common name of a magician or juggler, a sham-Latin invocation used in tricks, probably based on a perversion of the sacramental blessing from the Mass, Hoc est corpus meum "This is my body." The first to make this speculation on its origin apparently was English prelate John Tillotson (1630-1694).
I will speak of one man ... that went about in King James his time ... who called himself, the Kings Majesties most excellent Hocus Pocus, and so was called, because that at the playing of every Trick, he used to say, Hocus pocus, tontus tabantus, vade celeriter jubeo, a dark composure of words, to blinde the eyes of the beholders, to make his Trick pass the more currantly without discovery. [Thomas Ady, "A Candle in the Dark," 1655]
hod (n.)youdaoicibaDictYouDict
1570s, alteration of Middle English hott "pannier" (c. 1300), from Old French hotte "basket to carry on the back," apparently from Frankish *hotta or some other Germanic source (compare Middle High German hotze "cradle"). Altered by influence of cognate Middle Dutch hodde "basket."
