Online Etymology Dictionary

thresh (v.): Old English þrescan, þerscan, "to beat, sift grain by trampling or beating," from Proto-Germanic *threskan "to thresh," originally "to tread, to stamp noisily" (source also of Middle Dutch derschen, Dutch dorschen, Old High German dreskan, German dreschen, Old Norse þreskja, Swedish tröska, Gothic þriskan), from PIE root *tere- (1) "to rub, turn" (see throw (v.)).

The basic notion is of men or oxen treading out wheat; later, with the advent of the flail, the word acquired its modern extended sense of "to knock, beat, strike." The original Germanic sense is suggested by the use of the word in Romanic languages that borrowed it, such as Italian trescare "to prance," Old French treschier "to dance," Spanish triscar "to stamp the feet."
bop (n.): 1948, shortening of bebop or rebop; as a verb, "play bop music, play (a song) in a bop style," from 1948. It soon came to mean "do any sort of dance to pop music" (1956). Related: Bopped; bopping.

The musical movement had its own lingo, which was in vogue in U.S. early 1950s. "Life" magazine [Sept. 29, 1952] listed examples of bop talk: crazy "new, wonderful, wildly exciting;" gone (adj.) "the tops--superlative of crazy;" cool (adj.) "tasty, pretty;" goof "to blow a wrong note or make a mistake;" hipster "modern version of hepcat;" dig "to understand, appreciate the subtleties of;" stoned "drunk, captivated, ecstatic, sent out of this world;" flip (v.) "to react enthusiastically." [Life Sept. 29, 1952]
position (n.): late 14c., as a term in logic and philosophy, from Old French posicion "position, supposition" (Modern French position), from Latin positionem (nominative positio) "act or fact of placing, situation, position, affirmation," noun of state from past participle stem of ponere "put, place," from PIE *po-s(i)nere, from *apo- "off, away" (see apo-) + *sinere "to leave, let" (see site).

Meaning "proper place occupied by a person or thing" is from 1540s. Meaning "manner in which some physical thing is arranged or posed" first recorded 1703; specifically in reference to dance steps, 1778, sexual intercourse, 1883. Meaning "official station, employment" is from 1890.
pony (n.): 1650s, powny, from Scottish, apparently from obsolete French poulenet "little foal" (mid-15c.), diminutive of Old French poulain "foal," from Late Latin pullanus "young of an animal," from Latin pullus "young of a horse, fowl, etc." (see foal (n.)) [Skeat's suggestion, still accepted].

German, sensibly, indicates this animal by attaching a diminutive suffix to its word for "horse," which might yield Modern English *horslet. Modern French poney is a 19c. borrowing from English. Meaning "crib of a text as a cheating aid" (1827) and "small liquor glass" (1849) both are from notion of "smallness" (the former also "something one rides"). As the name of a popular dance, it dates from 1963. The U.S. Pony Express began 1860 (and operated about 18 months before being superseded by the transcontinental telegraph). The figurative one-trick pony is 1897, American English, in reference to circus acts.
strut (v.): "walk in a vain, important manner, walk with affected dignity," 1590s, from Middle English strouten "display one's clothes proudly, vainly flaunt fine attire" (late 14c.), earlier "to stick out, protrude, bulge, swell," from Old English strutian "to stand out stiffly, swell or bulge out," from Proto-Germanic *strut- (source also of Danish strutte, German strotzen "to be puffed up, be swelled," German Strauß "fight"), from PIE root *ster- (1) "strong, firm, stiff, rigid" (see stereo-).

Originally of the air or the attitude; modern sense, focused on the walk, first recorded 1510s. Related: Strutted; strutting. To strut (one's) stuff is first recorded 1926, from strut as the name of a dance popular from c. 1900. The noun meaning "a vain and affectedly dignified manner of walking" is from c. 1600.
pogo (n.): 1921, originally a registered trademark (Germany, 1919), of unknown origin, perhaps formed from elements of the names of the designers.
Hopping Stilts Are the New French Playthings. ... For France and especially Paris has taken to the "pogo" stick, a stick equipped with two rests for the feet. Inside of the stick is a strong spring so that the "pogoer" may take a series of jumps without straining his powers. The doctors claim that the jarring produced by the successive jumps do not serve to injure the spine, as one might at first suppose. This jumping habit is spreading through France and England and the eastern part of the United States. ["Illustrated World," Sept., 1921]
The fad periodically returned in U.S., but with fading intensity. As a leaping style of punk dance, attested from 1977. The newspaper comic strip by Walt Kelly debuted in 1948 and ran daily through 1975.
leap (v.): c. 1200, from Old English hleapan "to jump, spring clear of the ground by force of an initial bound; run, go; dance, leap upon (a horse)" (class VII strong verb; past tense hleop, past participle hleapen), from Proto-Germanic *hlaupan (source also of Old Saxon hlopan, Old Norse hlaupa, Old Frisian hlapa, Dutch lopen, Old High German hlouffan, German laufen "to run," Gothic us-hlaupan "to jump up"), of uncertain origin, with no known cognates beyond Germanic.
First loke and aftirward lepe [proverb recorded from mid-15c.]
Transitive sense "pass over by leaping" is from early 15c. Leap-frog, the children's game, is attested by that name from 1590s ("Henry V"); figurative use by 1704; as a verb from 1872. Related: Leaped; leaping.
lift (n.): mid-14c., "a man's load, as much as a man can carry;" late 15c., "act or action of lifting," from lift (v.). Figurative use from 1620s. Meaning "act of helping" is 1630s; that of "cheering influence" is from 1861. Sense of "elevator, hoisting machine to raise or lower between floors of a building" is from 1851; that of "upward force of an aircraft" is from 1902. Meaning "help given to a pedestrian by taking him along his way in a vehicle" is from 1712. As a dance move, from 1921. Sense of "heel-lift in a boot or shoe" is from 1670s.

The word once had a twin, Middle English lift "the air, the atmosphere; the sky, the firmament," from Old English lyft "air" (see loft (n.)).
jamboree (n.): 1866, "carousal, noisy drinking bout; any merrymaking," represented in England as a typical American English word, perhaps from jam (n.) on pattern of shivaree [Barnhart]. For the second element, Weekley suggests French bourree, a kind of rustic dance. Century Dictionary calls the whole thing "probably arbitrary." Klein thinks the word of Hindu origin (but he credits its introduction into English, mistakenly, to Kipling). Boy Scouts use is from 1920. It is noted earlier as a term in cribbage:
Jamboree signifies the combination of the five highest cards, as, for example, the two Bowers [jacks], Ace, King, and Queen of trumps in one hand, which entitles the holder to count sixteen points. The holder of such a hand, simply announces the fact, as no play is necessary; but should he play the hand as a Jambone, he can count only eight points, whereas he could count sixteen if he played it, or announced it as a Jamboree. ["The American Hoyle," New York, 1864]
Compare jambone "type of hand played by agreement in the card game of euchre."
Beguine (n.): late 15c., from French béguine (13c.), Medieval Latin beguina, a member of a women's spiritual order said to have been founded c.1180 in Liege in the Low Countries. They are said to take their name from the surname of Lambert le Bègue "Lambert the Stammerer," a Liege priest who was instrumental in their founding, and it's likely the word was pejorative at first.

The order generally preserved its reputation, though it quickly drew imposters who did not; nonetheless it eventually was condemned as heretical. A male order, called Beghards founded communities by the 1220s in imitation of them, but they soon degenerated (compare Old French beguin "(male) Beguin," also "hypocrite") and wandered begging in the guise of religion; they likely were the source of the words beg and beggar, though there is disagreement over whether Beghard produced Middle Dutch beggaert "mendicant" or was produced by it.

Cole Porter's "Begin the Beguine" (1935) refers to a kind of popular dance of West Indian origin, from French colloquial béguin "an infatuation, boyfriend, girlfriend," earlier "child's bonnet," and before that "nun's headdress" (14c.), from Middle Dutch beggaert, ultimately the same word.
freak (n.1): 1560s, "sudden and apparently causeless turn of mind," of unknown origin. Perhaps it is from a dialectal survival of a word related to Middle English friken "to move nimbly or briskly," from Old English frician "to dance" [OED, Barnhart]. There is a freking attested in mid-15c., apparently meaning "capricious behavior, whims." Or perhaps from Middle English frek "eager, zealous, bold, brave, fierce" (see freak (n.2)).

Sense of "capricious notion" (1560s) and "unusual thing, fancy" (1784) preceded that of "abnormally developed individual or production" (first in freak of nature, 1839, which was later popular in variety show advertisements for bearded ladies, albinos, etc.; compare Latin lusus naturæ, which was used in English from 1660s). As "drug user," attested from 1945. The sense in health freak, ecology freak, etc. is attested from 1908 (originally Kodak freak, a camera buff). Freak show attested from 1887.
Roger: masc. proper name, from Old French Rogier, from Old High German Hrotger, literally "famous with the spear," from hruod- "fame, glory" + ger "spear" (see gar (n.)). As a generic name for "a person," attested from 1630s. Slang meaning "penis" was popular c. 1650-c. 1870; hence the slang verb sense of "to copulate with (a woman)," attested from 1711.

The use of the word in radio communication to mean "yes, I understand" is attested from 1941, from the U.S. military phonetic alphabet word for the letter -R-, in this case an abbreviation for "received." Said to have been used by the R.A.F. since 1938. The Jolly Roger pirate flag is first attested 1723, of unknown origin; jolly here has its otherwise obsolete sense "high-hearted, gallant." Roger de Coverley, once a favorite English country dance, is so called from 1685, in reference to Addison's character in the "Spectator." French roger-bontemps "jovial, carefree man," is attested there from 15c.
measure (n.): c. 1200, "moderation, temperance, abstemiousness;" c. 1300, "instrument for measuring," from Old French mesure "limit, boundary; quantity, dimension; occasion, time" (12c.), from Latin mensura "measure" (see measure (v.)). Meaning "size or quantity as ascertained by measuring" is from early 14c. Meaning "action of measuring; standard measure of quantity; system of measuring; appointed or alloted amount of anything" is late 14c. Also from late 14c. are senses "proper proportion, balance." Sense of "that to which something is compared to determine its quantity" is from 1570s. Meaning "rhythmic pattern in music" is late 14c.; from mid-15c. in poetry, c. 1500 in dance. Meaning "treatment 'meted out' to someone" is from 1590s; that of "plan or course of action intended to obtain some goal" is from 1690s; sense of "legislative enactment" is from 1759. Phrase for good measure (late 14c.) is literally "ample in quantity, in goods sold by measure."
Jim Crow: "black man," 1838, American English, originally the name of a black minstrel character in a popular song-and-dance act by T.D. Rice (1808-1860) that debuted 1828 and attained national popularity by 1832:
Wheel about, an' turn about, an' do jis so;
Eb'ry time I wheel about, I jump Jim Crow.
Where and how Rice got it, or wrote it, is a mystery. Even before that, crow (n.) had been a derogatory term for a black man. As an adjective from 1833, in reference to the song. Association with segregation dates from 1841, in reference to separate railroad cars for blacks in Massachusetts. Modern use as a type of racial discrimination is from 1943. Jim Crow also could be a reference to someone's change of (political) principles (1837, from the "jump" in the song) or reversible machinery (1875, "wheel about").
On his arrival in Boston, Mr. [Charles Lenox] R[emond] went to the Eastern rail-road depot, in order to visit his parents in Salem; but, instead of being allowed to ride with other passengers, he was compelled to take a seat in what is contemptuously called the "Jim Crow car," as though he were a leper or a wild animal! [Annual Report of the Massachusetts Anti-Slavery Society, 1842]
henchman (n.): mid-14c., hengestman, later henshman (mid-15c.) "high-ranking servant (usually of gentle birth), attendant upon a king, nobleman, etc.," originally "groom," probably from man (n.) + Old English hengest "horse, stallion, gelding," from Proto-Germanic *hangistas (source also of Old Frisian hengst, Dutch hengest, German Hengst "stallion"), perhaps literally "best at springing," from PIE *kenku- (source also of Greek kekiein "to gush forth;" Lithuanian sokti "to jump, dance;" Breton kazek "a mare," literally "that which belongs to a stallion").

Perhaps modeled on Old Norse compound hesta-maðr "horse-boy, groom." The word became obsolete in England 17c., but it was retained in Scottish as "personal attendant of a Highland chief," in which sense Scott revived it in literary English from 1810. Sense of "obedient or unscrupulous follower" is first recorded 1839, probably somehow a misunderstanding of the word as used by Scott.
This officer is a sort of secretary, and is to be ready, upon all occasions, to venture his life in defence of his master; and at drinking-bouts he stands behind his seat, at his haunch, from whence his title is derived, and watches the conversation, to see if any one offends his patron. [Scott, notes to "Lady of the Lake," 1820; his proposed etymology is not now considered correct]
house (n.): Old English hus "dwelling, shelter, building designed to be used as a residence," from Proto-Germanic *husan (source also of Old Norse, Old Frisian hus, Dutch huis, German Haus), of unknown origin, perhaps connected to the root of hide (v.) [OED]. In Gothic only in gudhus "temple," literally "god-house;" the usual word for "house" in Gothic being according to OED razn.

Meaning "family, including ancestors and descendants, especially if noble" is from c. 1000. Zodiac sense is first attested late 14c. The legislative sense (1540s) is transferred from the building in which the body meets. Meaning "audience in a theater" is from 1660s (transferred from the theater itself, playhouse). Meaning "place of business" is 1580s. The specialized college and university sense (1530s) also applies to both buildings and students collectively, a double sense found earlier in reference to religious orders (late 14c.). As a dance club DJ music style, probably from the Warehouse, a Chicago nightclub where the style is said to have originated.

To play house is from 1871; as suggestive of "have sex, shack up," 1968. House arrest first attested 1936. House-painter is from 1680s. House-raising (n.) is from 1704. On the house "free" is from 1889. House and home have been alliteratively paired since c. 1200.
And the Prophet Isaiah the sonne of Amos came to him, and saide vnto him, Thus saith the Lord, Set thine house in order: for thou shalt die, and not liue. [II Kings xx:1, version of 1611]
monkey (n.): 1520s, likely from an unrecorded Middle Low German *moneke or Middle Dutch *monnekijn, a colloquial word for "monkey," originally a diminutive of some Romanic word, compare French monne (16c.); Middle Italian monnicchio, from Old Italian monna; Spanish mona "ape, monkey." In a 1498 Low German version of the popular medieval beast story Roman de Renart ("Reynard the Fox"), Moneke is the name given to the son of Martin the Ape; transmission of the word to English might have been via itinerant entertainers from the German states.

The Old French form of the name is Monequin (recorded as Monnekin in a 14c. version from Hainault), which could be a diminutive of some personal name, or it could be from the general Romanic word, which may be ultimately from Arabic maimun "monkey," literally "auspicious," a euphemistic usage because the sight of apes was held by the Arabs to be unlucky [Klein]. The word would have been influenced in Italian by folk etymology from monna "woman," a contraction of ma donna "my lady."

Monkey has been used affectionately for "child" since c. 1600. As a type of modern popular dance, it is attested from 1964. Monkey business attested from 1883. Monkey suit "fancy uniform" is from 1886. Monkey wrench is attested from 1858; its figurative sense of "something that obstructs operations" is from the notion of one getting jammed in the gears of machinery (compare spanner in the works). To make a monkey of someone is attested from 1900. To have a monkey on one's back "be addicted" is 1930s narcotics slang, though the same phrase in the 1860s meant "to be angry." There is a story in the Sinbad cycle about a tormenting ape-like creature that mounts a man's shoulders and won't get off, which may be the root of the term. In 1890s British slang, to have a monkey up the chimney meant "to have a mortgage on one's house." The three wise monkeys ("see no evil," etc.) are attested from 1926.
poetry (n.): late 14c., "poetry; a poem; ancient literature; poetical works, fables, or tales," from Old French poetrie (13c.), and perhaps directly from Medieval Latin poetria (c.650), from Latin poeta (see poet). In classical Latin, poetria meant "poetess."
... I decided not to tell lies in verse. Not to feign any emotion that I did not feel; not to pretend to believe in optimism or pessimism, or unreversible progress; not to say anything because it was popular, or generally accepted, or fashionable in intellectual circles, unless I myself believed it; and not to believe easily. [Robinson Jeffers (1887-1962), forward to "Selected Poems"]

Poetry -- meaning the aggregate of instances from which the idea of poetry is deduced by every new poet -- has been increasingly enlarged for many centuries. The instances are numerous, varied and contradictory as instances of love; but just as 'love' is a word of powerful enough magic to make the true lover forget all its baser and falser, usages, so is 'poetry' for the true poet. [Robert Graves, "The White Goddess"]
Figurative use from 1660s. Old English had metergeweorc "verse," metercræft "art of versification." Modern English lacks a true verb form in this group of words, though poeticize (1804), poetize (1580s, from French poétiser), and poetrize (c. 1600) have been tried. Poetry in motion (1826) perhaps is from poetry of motion (1813) "dance" (also poetry of the foot, 1660s).
twist (n.): mid-14c., "flat part of a hinge" (now obsolete), probably from Old English -twist "divided object; fork; rope" (as in mæsttwist "mast rope, stay;" candeltwist "wick"), from Proto-Germanic *twis-, from PIE root *dwo- (see two). Original senses suggest "dividing in two" (source also of cognate Old Norse tvistra "to divide, separate," Gothic twis- "in two, asunder," Dutch twist, German zwist "quarrel, discord," though these senses have no equivalent in English), but later ones are of "combining two into one," hence the original sense of the word may be "rope made of two strands."

Meaning "thread or cord composed of two or more fibers" is recorded from 1550s. Meaning "act or action of turning on an axis" is attested from 1570s. Sense of "beverage consisting of two or more liquors" is first attested c. 1700. Meaning "thick cord of tobacco" is from 1791. Meaning "curled piece of lemon, etc., used to flavor a drink" is recorded from 1958. Sense of "unexpected plot development" is from 1941.

The popular rock 'n' roll dance craze is from 1961, so called from the motion involved, but twist was used to describe popular dances in 1894 and again in the 1920s. To get one's knickers in a twist "be unduly agitated" is British slang first attested 1971.
shake (v.): Old English sceacan "move (something) quickly to and fro, brandish; move the body or a part of it rapidly back and forth;" also "go, glide, hasten, flee, depart" (related to sceacdom "flight"); of persons or parts of the body, "to tremble" especially from fever, cold, fear" (class VI strong verb; past tense scoc, past participle scacen), from Proto-Germanic *skakanan (source also of Old Norse, Swedish skaka, Danish skage "to shift, turn, veer"). No certain cognates outside Germanic, but some suggest a possible connection to Sanskrit khaj "to agitate, churn, stir about," Old Church Slavonic skoku "a leap, bound," Welsh ysgogi "move."

Of the earth in earthquakes, c. 1300. Meaning "seize and shake (someone or something else)" is from early 14c. In reference to mixing ingredients, etc., by shaking a container from late 14c. Meaning "to rid oneself of by abrupt twists" is from c. 1200, also in Middle English in reference to evading responsibility, etc. Meaning "weaken, impair" is from late 14c., on notion of "make unstable."

To shake hands dates from 1530s. Shake a (loose) leg "hurry up" first recorded 1904; shake a heel (sometimes foot) was an old way to say "to dance" (1660s); to shake (one's) elbow (1620s) meant "to gamble at dice." Phrase more _____ than you can shake a stick at is attested from 1818, American English. To shake (one's) head as a sign of disapproval is recorded from c. 1300.
leg (n.): late 13c., from a Scandinavian source, probably Old Norse leggr "a leg, bone of the arm or leg," from Proto-Germanic *lagjaz (cognates Danish læg, Swedish läg "the calf of the leg"), a word with no certain ulterior connections. Perhaps from a PIE root meaning "to bend" [Buck]. For Old Norse senses, compare Bein, the German word for "leg," in Old High German "bone, leg" (see bone (n.)). Replaced Old English shank (n.), itself also perhaps from a root meaning "crooked."

Distinguished from an arm, leg, or fin in being used for support. Of triangle sides from 1650s (translating Greek skelos, literally "leg"). Extended to furniture supports from 1670s. Meaning "part of pants which cover the leg" is from 1570s. By 1870s the as an adjective it had a salacious suggestion of artistic displays focused on the female form, such as leg-piece in theater jargon, leg-business as slang for "ballet."

The meaning "a part or stage of a journey or race" (1920) is from earlier sailing sense of "a run made by a ship on a single tack when beating to windward" (1867), which was usually qualified as long leg, short leg, etc. Slang phrase shake a leg is attested from 1869 as "dance," 1880 as "hurry up." To be on (one's) last legs "at the end of one's life" is from 1590s, the notion is of something that serves one for support and keeps one moving. To take leg bail was old slang for "run away" (1774).
