Boccaccio

the name means "big-mouth" in Italian, from boccaccia, augmentative of bocca "mouth" (see bouche).ETD Boccaccio.2

Boche (n.)

"German soldier in World War I," 1914, perhaps from French slang boche "rascal," applied to the Germans; a word of unknown origin. Another theory traces it to French Allemand "German," in eastern French Al(le)moche, altered contemptuously to Alboche by association with caboche, a slang word for "head," literally "cabbage" (compare tete de boche, French for "German" in an 1887 slang dictionary). None of the French terms is older than mid-19c.ETD Boche (n.).2

bodega (n.)

1846, "wine shop," from Mexican Spanish, from Spanish bodega "a wine shop; wine-cellar," from Latin apotheca, from Greek apothēkē "depot, store" (see apothecary). Since 1970s in American English it has come to mean "corner convenience store or grocery," especially in a Spanish-speaking community, but in New York City and some other places used generically. Also a doublet of boutique. Italian cognate bottega entered English c. 1900 as "artist's workshop or studio," especially in Italy.ETD bodega (n.).2

Bodhisattva (n.)

body (n.)

Middle English bodi, from Old English bodig "trunk of a man or beast; the whole physical structure of a human or animal; material frame, material existence of a human; main or principal part of anything," related to Old High German botah, but otherwise of unknown origin. Not elsewhere in Germanic, and the word has died out in German (replaced by Leib, originally "life," and Körper, from Latin), "but in English body remains as a great and important word" [OED].ETD body (n.).2

The extension to "a person, a human being" is by c. 1300. The meaning "main part" of anything was in late Old English, hence its use in reference to vehicles (1520s). From 1580s as "part of the dress which covers the body."ETD body (n.).3

It is attested from 1590s as "main part of a group, any number of individuals spoken of collectively" and from 1660s as "main portion of a document." Contrasted with soul at least since mid-13c. The meaning "corpse" ("dead body") is from c. 1200. The word was transferred to matter generally in Middle English (as in heavenly body, late 14c.).ETD body (n.).4

Body politic "the nation, the state, whole body of people living under an organized government" is recorded from late 15c., with French word order. Body image was coined 1934. Body count "number of enemy killed in battle or otherwise" is from 1968, from the Vietnam War. Body language is attested from 1967, perhaps from French langage corporel (1966). Body-snatcher "one who secretly disinters the bodies of the recently dead for dissection" is from 1834. Defiant phrase over my dead body attested by 1833.ETD body (n.).5

For the spelling, compare deuce. In modern use, an outer laced garment covering the waist and bust worn by women, often as an ornament.ETD bodice (n.).2

Bodice-ripper for "racy romance novel" is from 1981. Related: Bodiced.ETD bodice (n.).3

bodkin (n.)

c. 1300, badeken, boydekin, "short, small dagger, pointed weapon," a word of unknown origin. The ending suggests a diminutive formation, and Celtic has been suggested as the source of the primitive, "In default of finding it elsewhere" [OED], but Century Dictionary rejects this.ETD bodkin (n.).2

Boeotian (adj.)

"ignorant, dull," 1590s, from Boeotia, the district around Thebes in ancient Greece (said to have been so called for its cattle pastures; from Greek bous "ox," from PIE root *gwou- "ox, bull, cow"), whose inhabitants were characterized as proverbially dull and countrified by their neighbors the Athenians, who thought Boeotia "a canton hopelessly behind the times, a slow canton, as the nimble Attics would say, a glorious climate for eels, but a bad air for brains" [B.L. Gildersleeve, "Pindar: The Olympian and Pythian Odes"]. The Boeotians presumably held reciprocal opinions, but their great writers, Plutarch and Pindar, though patriots, are full of praise for Athenian deeds and institutions.ETD Boeotian (adj.).2

Boer (n.)

"Dutch colonist in South Africa," 1824, from Dutch boer "farmer," from Middle Dutch, cognate with Old English gebur "dweller, farmer, peasant," and thus related to bower, German Bauer, and the final syllable of neighbor; from PIE root *bheue- "to be, exist, grow."ETD Boer (n.).2

The Boer War (1899-1902), in which Great Britain defeated the South African Republic of Transvaal and Orange Free State, was technically the Second Boer War, there having been a brief preview 1880-1881.ETD Boer (n.).3

boffin (n.)

"person engaged in innovative research," especially in aviation, 1945; earlier "elderly naval officer" (1941), a word of uncertain origin but probably from one of the "Mr. Boffins" of English literature (as in "Our Mutual Friend").ETD boffin (n.).2

strikingly successful, by 1961, show biz slang, probably echoic of a "hit."ETD boffo (adj.).2

bog (v.)

bog (n.)

"wet, soft, spongy ground with soil chiefly composed of decaying vegetable matter," c. 1500, from Gaelic and Irish bogach "bog," from adjective bog "soft, moist," from Proto-Celtic *buggo- "flexible" (from PIE root *bheug- "to bend").ETD bog (n.).2

bogart (v.)

drug slang, "to keep a joint in your mouth," dangling from the lip like Humphrey Bogart's cigarette in the old movies, instead of passing it on, by 1968, in "Don't Bogart That Joint" by Fraternity of Man. The word also was used 1960s with notions of "get something by intimidation, be a tough guy" (again with reference to the actor and the characters he typically played). Sixties slang, but the notion isn't new; in old drinking slang, Captain Cork was "a man slow in passing the bottle."ETD bogart (v.).2

bogey (n.2)

in golf, c. 1891, originally "number of strokes a good player is supposed to need for a given hole or course;" later, "score one over par" (1946); from the same source as bogey (n.1), on the notion of a "phantom" opponent, represented by the "ground score." The word was in vogue at the time in Britain through the popularity of a music-hall tune "Hush, Hush, Hush, Here Comes the Bogey Man."ETD bogey (n.2).2

Other early golfing sources give it an American origin. As a verb, attested by 1948.ETD bogey (n.2).3

bogey (n.1)

World War II aviator slang for "unidentified aircraft, presumably hostile," probably ultimately from bog/bogge, attested 16c.-17c., a dialectal variant of Middle English bugge "a frightening specter" (see bug (n.)).ETD bogey (n.1).2

If so, bogey shares ancestry with, and might have arisen from, dialect words for "ghost, specter, the devil," such as bogeyman "haunting specter, object of fear" (16c.), boggart "specter that haunts a gloomy spot" (c. 1570, in Westmoreland, Lancashire, Cheshire, and Yorkshire), and compare bogey (n.2). The earliest modern form appears to be Scottish bogle "ghost," attested from c. 1500 and popularized c. 1800 in English literature by Scott, Burns, etc.ETD bogey (n.1).3

bogeyman (n.)

"haunting specter, object of fear," 16c.; see bogey (n.1) + man (n.).ETD bogeyman (n.).2

boggart (n.)

also boggard, "specter, goblin, sprite," especially one supposed to haunt a particular spot, 1560s; see bug (n.).ETD boggart (n.).2

boggy (adj.)

"swampy, like a bog; full of bogs," 1580s, from bog (n.) + -y (2). Related: Bogginess.ETD boggy (adj.).2

boggle (v.)

1590s, "to start with fright (as a startled horse does), shy, take alarm," from Middle English bugge "specter" (among other things, supposed to scare horses at night); see bug (n.); also compare bogey (n.1), boggart.ETD boggle (v.).2

The meaning " hesitate, stop as if afraid to proceed in fear of unforeseen difficulties" is from 1630s; the transitive sense of "confound, cause to hesitate" is from 1640s. As a noun from 1650s. Related: Boggled; boggling; boggler (from c. 1600 as "one who hesitates").ETD boggle (v.).3

Bogota

capital of Colombia, founded 1530s, the name is from Chibcha (an indigenous language) Bacata, native name of a settlement of the Muisca people that stood there when the Spanish arrived.ETD Bogota.2

bog-trotter (n.)

applied to the "wild Irish" from 1670s; see bog + trot (v.).ETD bog-trotter (n.).2

bogus (adj.)

"counterfeit, spurious, sham," 1839, from a noun (1838) meaning "counterfeit money, spurious coin," American English slang, apparently from a word applied (according to OED first in Ohio in 1827) to a counterfeiter's apparatus.ETD bogus (adj.).2

Some trace this to tantrabobus, also tantrabogus, a late 18c. colloquial Vermont word for any odd-looking object (in later 19c. use "the devil"), which might be connected to tantarabobs, recorded as a Devonshire name for the devil. Others trace it to the same source as bogey (n.1). Related: Bogusly; bogusness.ETD bogus (adj.).3

boh (interj.)

see boo.ETD boh (interj.).2

Bohemia

central European kingdom, mid-15c., Beeme, from French Boheme "Bohemia," from Latin Boiohaemum (Tacitus), from Boii, the Celtic people who settled in what is now Bohemia (and were driven from it by the Germanic Marcomans early 1c.; singular Boius, fem. Boia, perhaps literally "warriors") + Proto-Germanic *haimaz "home" (see home (n.)). Attested from 1861 in meaning "community of artists and social Bohemians" or in reference to a district where they live (see bohemian).ETD Bohemia.2

bohemian (n.)

"a gypsy of society; person (especially an artist) who lives a free and somewhat dissipated life, despising conventionalities and having little regard for social standards," 1848, from a transferred sense of French bohemién "a Bohemian; a Gypsy," from the country name (see Bohemia). The Middle English word for "a resident or native of Bohemia" was Bemener.ETD bohemian (n.).2

The French used bohemién since 15c. to also mean "Gypsy." The Roma were wrongly believed to have come from there, perhaps because their first appearance in Western Europe may have been immediately from Bohemia, or because they were confused with the 15c. Bohemian Hussite heretics, who were driven from their country about that time.ETD bohemian (n.).3

The transferred sense, in reference to unconventional living, is attested in French by 1834 and was popularized by Henri Murger's stories from the late 1840s later collected as "Scenes de la Vie de Boheme" (the basis of Puccini's "La Bohème"). It appears in English 1848 in Thackary's "Vanity Fair."ETD bohemian (n.).4

Hence also the adjective, "unconventional, free from social restraints" (1848).ETD bohemian (n.).5

Bohunk (n.)

U.S. derogatory slang for "lower-class immigrant from Central or Eastern Europe," by 1899, probably from Bohemian (see Bohemia) + a distortion of Hungarian (see Hungary).ETD Bohunk (n.).2

boy (n.)

mid-13c., boie "servant, commoner, knave" (generally young and male); c. 1300, "rascal, ruffian, knave; urchin," mid-14c. as "male child before puberty" (possibly extended from the "urchin" sense). A word of unknown origin.ETD boy (n.).2

Possibly from Old French embuie "one fettered," from Vulgar Latin *imboiare, from Latin boia "leg iron, yoke, leather collar," from Greek boeiai dorai "ox hides." (Words for "boy" double as "servant, attendant" across the Indo-European map — compare Italian ragazzo, French garçon, Greek pais, Middle English knave, Old Church Slavonic otroku — and often it is difficult to say which meaning came first.)ETD boy (n.).3

But it also appears to be identical with East Frisian boi "young gentleman," and perhaps with Dutch boef "knave," from Middle Dutch boeve, perhaps from Middle Low German buobe. This suggests a gradational relationship to babe. Another conjecture:ETD boy (n.).4

Used slightingly of young men in Middle English, also in familiar or contemptuous use of criminal toughs or men in the armed services. In some local uses "a man," without reference to age (OED lists "in Cornwall, in Ireland, in the far West of the U.S."). The meaning "male negro slave or Asian personal servant of any age" attested from c. 1600.ETD boy (n.).5

Extended form boyo is attested from 1870. Emphatic exclamation oh, boy is attested by 1917. Boy-meets-girl "typical of a conventional romance" is from 1945; the phrase itself is from 1934 as a dramatic formula. Boy-crazy "eager to associate with males" is from 1923.ETD boy (n.).6

boil (v.)

early 13c. (intransitive) "to bubble up, be in a state of ebullition," especially from heat, from Old French bolir "boil, bubble up, ferment, gush" (12c., Modern French bouillir), from Latin bullire "to bubble, seethe," from PIE *beu- "to swell" (see bull (n.2)). The native word is seethe. The figurative sense, of passions, feelings, etc., "be in an agitated state" is from 1640s.ETD boil (v.).2

The transitive sense "put into a boiling condition, cause to boil" is from early 14c. The noun is from mid-15c. as "an act of boiling," 1813 as "state of boiling." Related: Boiled; boiling. Boiling point "temperature at which a liquid is converted into vapor" is recorded from 1773.ETD boil (v.).3

boil (n.)

"hard tumor," altered from Middle English bile (Kentish bele), perhaps by association with the verb; from Old English byl, byle "boil, carbuncle," from West Germanic *buljon- "swelling" (source also of Old Frisian bele, Old High German bulia, German Beule). Perhaps ultimately from PIE root *bhel- (2) "to blow, swell," or from *beu- "to grow, swell" (see bull (n.2); also compare boast (n.)). Compare Old Irish bolach "pustule," Gothic ufbauljan "to puff up," Icelandic beyla "hump."ETD boil (n.).2

boiler (n.)

1540s, "person who boils," agent noun from boil (v.). The meaning "vessel for boiling" is from 1725; the specific sense of "strong metallic structure in which steam is generated for driving engines" is from 1757.ETD boiler (n.).2

boilermaker (n.)

also boiler-maker, "a maker of boilers for engines," 1814, from boiler (n.) + maker. The meaning "shot of whiskey with a glass of beer" is short for boilermaker's delight (1910), a term for strong cheap whiskey, so called in jest from the notion that it also would clean the scales from the interior of a boiler.ETD boilermaker (n.).2

boilerplate (n.)

1831, "iron rolled in large, flat plates for use in making steam boilers," from boiler + plate (n.). In newspaper (and now information technology) slang, the sense of "unit of writing that can be used over and over without change" is attested by 1887. The connecting notion probably is the permanence of the prepared plate compared to set type: From the 1870s to the 1950s, publicity items were cast or stamped in metal ready for the printing press and distributed to country newspapers as filler. An early provider was the American Press Association (1882). The largest supplier later was Western Newspaper Union.ETD boilerplate (n.).2

An older name for it was plate-matter "type cast in a number of stereotype plates for insertion in different newspapers" (1878). Plate (n.) is attested by 1824 in printing as "a cast of a page of composed movable types."ETD boilerplate (n.).3

boink

"have sex with" (v.); "the sex act" (n.), slang by c. 2000, perhaps a bouncier form of bonk in its popular venery sense. Related: Boinked; boinking.ETD boink.2

Boise

city in Idaho, U.S., from French-Canadian boisé, literally "wooded," from French bois "wood," which (with Italian bosco, Spanish bosque, Medieval Latin boscus) apparently is borrowed from the Germanic root of bush (n.). Medieval Latin boscus was used especially of "woodland pasture."ETD Boise.2

boisterous (adj.)

late 15c., boistreous, "rough, coarse," an unexplained alteration of Middle English boistous (c. 1300) "rough, coarse, clumsy, violent," which itself is of unknown origin, perhaps from Anglo-French bustous "rough (road)," itself perhaps from Old French boisteos "curved, lame; uneven, rough" (Modern French boiteux), itself of obscure origin. Another guess traces it via Celtic to Latin bestia.ETD boisterous (adj.).2

Of persons, "turbulent, clamorous," 1560s; OED says originally "in a distinctly bad sense," but by 1680s gradually passing into "abounding in rough but good-natured activity bordering upon excess." Related: Boisterously; boisterousness.ETD boisterous (adj.).3

bok choy (n.)

also pak choi, type of Chinese cabbage, by 1967, from Cantonese, literally "white vegetable;" earlier Englished as pak-tsae (1847), with a variety of spellings in between.ETD bok choy (n.).2

bold (adj.)

Middle English bold, from Old English beald (West Saxon), bald (Anglian) "stout-hearted, brave, confident, strong," from Proto-Germanic *balthaz (source also of Old High German bald "bold, swift," in names such as Archibald, Leopold, Theobald; Gothic balþei "boldness;" Old Norse ballr "frightful, dangerous"), perhaps (Watkins) from PIE *bhol-to-, suffixed form of root *bhel- (2) "to blow, swell."ETD bold (adj.).2

The meaning "requiring or exhibiting courage" is from mid-13c. Also in a bad sense, "audacious, presumptuous, overstepping usual bounds" (c. 1200). From 1670s as "standing out to view, striking the eye." Of flavors (coffee, etc.) from 1829.ETD bold (adj.).3

The noun meaning "those who are bold" is from c. 1300 in both admiring and disparaging senses. Old French and Provençal baut "bold," Italian baldo "bold, daring, fearless" are Germanic loan-words. Related: Boldly; boldness.ETD bold (adj.).4

bold-face (n.)

also boldface, in typography, "having a thick or fat face," 1845, from bold (adj.) + face (n.). In reference to types, bold (adj.) is attested from 1790, perhaps from its secondary sense "easily visible, striking to the eye."ETD bold-face (n.).2

bole (n.)

"body or trunk of a tree," early 14c., from Old Norse bolr "tree trunk," from Proto-Germanic *bulas (source also of Middle Dutch bolle "trunk of a tree"), from PIE root *bhel- (2) "to blow, swell."ETD bole (n.).2

bolero (n.)

kind of Spanish dance in 3/4 time, "intended to represent the course of love from extreme shyness to extreme passion" [Century Dictionary], 1787, from Spanish, probably from bola "ball" (and perhaps with reference to "whirling motion"), from Latin bulla "round swelling, knob" (see bull (n.2)). In reference to a type of short jacket (worn in Spain by men, by women elsewhere), it is recorded in English by 1864.ETD bolero (n.).2

Bolivia

South American republic, founded 1825, named for Simon Bolivar (1783-1830), statesman and soldier.ETD Bolivia.2

boll (n.)

Middle English bolle, from Old English bolla "bowl, cup, pot, round vessel for containing liquids," merged from 13c. with Middle Dutch bolle "round object," both from Proto-Germanic *bul-, from PIE root *bhel- (2) "to blow, swell." Influenced in meaning by Latin bulla "bubble, ball" (see bull (n.2)).ETD boll (n.).2

The sense was extended c. 1500 to "round seed pod of flax or cotton." Boll weevil, which damages cotton bolls, is so called from 1895, American English.ETD boll (n.).3

A case of entomology meddling in etymology.ETD boll (n.).4
