late 14c., "narrative with a happy ending; any composition intended for amusement," from Old French comedie (14c.), "a poem" (not in the theatrical sense) and directly from Latin comoedia, from Greek kōmōidia "a comedy, amusing spectacle," probably [Beekes] from kōmōidos "actor or singer in the revels," from kōmos "revel, carousal, merry-making, festival" + aoidos "singer, poet," from aeidein "to sing," which is related to ōidē (see ode).
The passage on the nature of comedy in the Poetic of Aristotle is unfortunately lost, but if we can trust stray hints on the subject, his definition of comedy (which applied mainly to Menander) ran parallel to that of tragedy, and described the art as a purification of certain affections of our nature, not by terror and pity, but by laughter and ridicule. [Rev. J.P. Mahaffy, "A History of Classical Greek Literature," London, 1895]
The origin of Greek komos is uncertain; perhaps it is from a PIE *komso- "praise," and cognate with Sanskrit samsa "praise, judgment." Beekes suggests Pre-Greek. The old derivation from kome "village" is not now regarded.
The classical sense of the word was "amusing play or performance with a happy ending," which is similar to the modern one, but in the Middle Ages the word meant poems and stories generally (albeit ones with happy endings), such as Dante's "Commedia." The revival of learning 16c. recovered the ancient comedies and shifted the sense of the word to "branch of drama addressing primarily the humorous and ridiculous" (opposed to tragedy). In 18c. this was somewhat restricted to "humorous, but not grossly comical, drama" (opposed to farce).
Comedy aims at entertaining by the fidelity with which it presents life as we know it, farce at raising laughter by the outrageous absurdity of the situation or characters exhibited, & burlesque at tickling the fancy of the audience by caricaturing plays or actors with whose style it is familiar. [Fowler]
Meaning "comic play or drama" is from 1550s (the first modern comedy in English was said to be Nicholas Udall's "Roister Doister"). Extended sense "humorous or comic incident or events in life" is from 1560s. Generalized sense of "quality of being amusing" dates from 1877.
spectral being in a human body who maintains semblance of life by leaving the grave at night to suck the warm blood of the living as they sleep, 1732, vampyre, from French vampire (18c.) or German Vampir (1732, like the English word first in an account of Hungarian vampires), from Hungarian vampir, from Old Church Slavonic opiri (source also of Serbian vampir, Bulgarian vapir, Ukrainian uper), said by Slavic linguist Franc Miklošič to be ultimtely from Kazan Tatar ubyr "witch," but Max Vasmer, an expert in this linguistic area, finds that phonetically doubtful.
An Eastern European creature popularized in English by late 19c. gothic novels, however there are scattered English accounts of night-walking, blood-gorged, plague-spreading undead corpses from as far back as 1196. Figurative sense of "person who preys on others" is from 1741. Applied 1774 by French biologist Buffon to a species of South American blood-sucking bat. Related: Vampiric.
MR. D'Anvers tells of a Conversation he had about a certain Prodigy, mention'd in the News Papers of March last, viz. that in the Village of Medreyga in Hungary, certain dead Bodies (call'd there Vampyres) had kill'd several Persons by sucking out all their Blood : That Arnold Paul, an Heyduke, having kill'd four Persons after he was dead, his Body was taken up 40 Days after, which bled at the Nose, Mouth and Ears : That, according to Custom, they drove a Stake thro' his Heart, at which he gave horrid Groan, and lost a great deal of Blood. And that all such as have been tormented or kill'd by Vampyres, become Vampyres when they are dead. [London Journal, May 20, 1732, quoted in Weekly Essays, May 1732]
The spread of the story about this time is perhaps traceable to a pamphlet published in 1732, the title page of which reads: Dissertationem De Hominibus Post Mortem Sanguisugis, Vulgo Sic Dictis Vampyren, Auctoritate Inclyti Philosophorum Ordinis, Publico Eruditorum Examini Die XXX. Aug. An. MDCCXXXII. Submittent M. Io. Christophorus Pohlius, Lignicens. Silesius Et Io. Gottlob Hertelius, Philos. Et Med. Stud.
popular name of a common bird of Europe, Asia, and America, known for its chattering, acquisitiveness, curiosity, and mimicry, c. 1600, earlier simply pie (mid-13c.).
The first element is Mag, nickname for Margaret, long used in proverbial and slang English for qualities associated generally with women, especially in this case "idle chattering" (as in Magge tales "tall tales, nonsense," early 15c.; also compare French margot "magpie," from Margot, pet form of Marguerite). The name Margaret, and its reduced forms Mag, Madge, diminutive Maggie, also has long been familiarly applied to birds. Pies were proverbial since Middle English for chattering (as were jays), hence the application of pie to a prattling gossip or tattler, also "sly person, informer" (late 14c.) and in 15c.-16c. a wily pie (or wyly pye) was "a cunning person."
The second element, pie, is the earlier name of the bird, from Old French pie, from Latin pica "magpie" (source also of Spanish pega), fem. of picus "woodpecker," from PIE root *(s)peik- "woodpecker, magpie" (source also of Umbrian peica "magpie," Sanskrit pikah "Indian cuckoo," Old Norse spætr, German Specht "woodpecker"); possibly from PIE root *pi-, denoting pointedness, of the beak. The application to pies might be because the magpie also has a long, pointed tail.
The birds are proverbial for pilfering and hoarding and for their indiscriminate appetites (see pica (n.2)); they can be taught to speak, and have been regarded since the Middle Ages as ill omens.
Whan pyes chatter vpon a house it is a sygne of ryghte euyll tydynges. 
Divination by numbering magpies is attested from c. 1780 in Lincolnshire; the rhyme varies from place to place, the only consistency being that one is bad, two are good.
The councils which magpies appear to hold together, at particular seasons, commonly called "folkmotes," are associated in the minds of many with superstitious and ominous notions. The innocent objects of terror, while meeting together most probably for the purpose of choosing mates, are supposed to be conspiring and clubbing their wits, for the weal or woe of the inhabitants of the neighbouring village. If they are of an even number and carry on their cheerful, noisy chatter, it is supposed to betoken good to old and young—but if there is an odd magpie perched apart from the rest, silent, and disconsolate, the reverse of this is apprehended, and mischievous consequences are inevitably expected. [The Saturday Magazine, Jan. 23, 1841]
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) as an aside to his explanation that those born on Christmas Eve cannot see spirits. Denham was an early folklorist who concentrated on Northumberland, Durham, Westmoreland, Cumberland, the Isle of Man, and Scotland. This was printed in volume 2 of "The Denham Tracts" [ed. James Hardy, London: Folklore Society, 1895], a compilation of Denham's scattered publications.
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" [in English court records for Hughes vs. Humphreys, a weights-and-measures case from Wales]. Hobbitry attested from 1947.
