beating (n.)
c. 1200, beatunge "action of inflicting blows," verbal noun from beat (v.). Meaning "pulsation" is recorded from c. 1600. Nautical sense of "sailing against the wind" is by 1883.
beatitude (n.)
early 15c., "supreme happiness," from Middle French béatitude (15c.) and directly from Latin beatitudinem (nominative beatitudo) "state of blessedness," from past participle stem of beare "make happy" (see Beatrice). Attested from 1520s as "a declaration of blessedness" (usually plural, beatitudes, especially in reference to the Sermon on the Mount).
Beatlemania (n.)
1963; see Beatles + mania.
The social phenomenon of Beatlemania, which finds expression in handbags, balloons and other articles bearing the likeness of the loved ones, or in the hysterical screaming of young girls whenever the Beatle Quartet performs in public. ["London Times," Dec. 27, 1963]
Beatles (n.)
seminal rock and pop group formed in Liverpool, England; named as such 1960 (after a succession of other names), supposedly by then-bassist Stuart Sutcliffe, from beetles (on model of Buddy Holly's band The Crickets) with a pun on the musical sense of beat. Their global popularity dates to 1963.
beatnik (n.)
coined 1958 by San Francisco newspaper columnist Herb Caen during the heyday of -nik suffixes in the wake of Sputnik. From Beat generation (1952), associated with beat (n.) in its meaning "rhythm (especially in jazz)" as well as beat (adj.) "worn out, exhausted," and Century Dictionary (1902) has slang beat (n.) "a worthless, dishonest, shiftless fellow." Originator Jack Kerouac (1922-1969) in 1958 connected it with beatitude.
The origins of the word beat are obscure, but the meaning is only too clear to most Americans. More than the feeling of weariness, it implies the feeling of having been used, of being raw. It involves a sort of nakedness of the mind. ["New York Times Magazine," Oct. 2, 1952]

"Beat" is old carny slang. According to Beat Movement legend (and it is a movement with a deep inventory of legend), Ginsberg and Kerouac picked it up from a character named Herbert Huncke, a gay street hustler and drug addict from Chicago who began hanging around Times Square in 1939 (and who introduced William Burroughs to heroin, an important cultural moment). The term has nothing to do with music; it names the condition of being beaten down, poor, exhausted, at the bottom of the world. [Louis Menand, "New Yorker," Oct. 1, 2007]
Beatrice
fem. proper name, from French Béatrice, from Latin beatrix, fem. of beatricem "who makes happy," from beatus "happy, blessed," past participle of beare "make happy, bless," which is possibly from PIE *dweye-, suffixed form of root *deu- (2) "to do, perform; show favor, revere." De Vaan finds the connection "semantically attractive, but the morphology is unclear."
beau (n.)
"attendant suitor of a lady," 1720, from French beau "the beautiful," noun use of an adjective, from Old French bel "beautiful, handsome, fair, genuine, real" (11c.), from Latin bellus "handsome, fine, pretty, agreeable" (see belle). Meaning "man who attends excessively to dress, etiquette, etc.; a fop; a dandy" is from 1680s, short for French beau garçon "pretty boy" (1660s). Plural is beaus or beaux. Beau Brummel, arbiter of men's fashion in Regency London, was George B. Brummel, gentleman (1778-1840).
beau-ideal (n.)
"beautifulness or excellence as an abstract ideal," 1801, from French beau idéal "the ideal beauty, ideal excellence," in which beau is the subject, but as English word-order usually has the adjective first, the sense has shifted in English toward "perfect type or model."
beau-monde (n.)
also beau monde, "the fashionable world," 1714, French, from beau (see beau) + monde, from Latin mundus "world" (see mundane).
beaucoup
French, literally "a great heap" (13c.), from beau "fine, great" (see beau (n.)) + coup "a stroke," also "a throw," hence, "a heap" (see coup (n.)). Compare Spanish golpe "multitude," from the same Latin source.

The sudden death of a young woman a little over a week ago in a down-town "beauty parlor" has served to direct public attention to those institutions and their methods. In this case, it seems, the operator painted on or injected into the patron's facial blemish a 4-per-cent cocaine solution and then applied an electrode, the sponge of which was saturated with carbolized water. ["The Western Druggist," October 1894]
beautification (n.)
"act of making beautiful," 1630s, from beauty + -fication "a making or causing."
beautiful (adj.)
mid-15c., "pleasing to the eye (or ear) or mind or soul," from beauty + -ful. The beautiful people "the fashionable set" first attested 1964 in "Vogue" magazine (it also was the title of a 1941 play by U.S. dramatist William Saroyan). As a noun, "that which possesses beauty," from 1756. House Beautiful is from "Pilgrim's Progress," where it is a proper name of a place. Related: Beautifully.

beauty (n.)
early 14c., bealte, "physical attractiveness," also "goodness, courtesy," from Anglo-French beute, Old French biauté "beauty, seductiveness, beautiful person" (12c., Modern French beauté), earlier beltet, from Vulgar Latin bellitatem (nominative bellitas) "state of being pleasing to the senses" (source also of Spanish beldad, Italian belta), from Latin bellus "pretty, handsome, charming," in classical Latin used especially of women and children, or ironically or insultingly of men, perhaps from PIE *dw-en-elo-, diminutive of root *deu- (2) "to do, perform; show favor, revere." Famously defined by Stendhal as la promesse de bonheur "the promise of happiness."
[I]t takes the one hundred men in ten million who understand beauty, which isn't imitation or an improvement on the beautiful as already understood by the common herd, twenty or thirty years to convince the twenty thousand next most sensitive souls after their own that this new beauty is truly beautiful. [Stendhal, "Life of Henry Brulard"]
Replaced Old English wlite. Concrete meaning "a beautiful woman" in English is first recorded late 14c. Beauty-sleep "sleep before midnight" (popularly regarded as the most refreshing) is attested by 1850. Beauty-spot "dark spot placed on the face formerly by women to heighten beauty" is from 1650s. Beauty-contest is from 1885; beauty-queen is from 1922 (earlier it was a show-name of cattle and hogs). Beauté du diable (literally "devil's beauty") is used as a French phrase in English from 1825.
But as it is hardly possible to define all the properties which constitute beauty, we may observe in general, that beauty consists in whatever pleases the eye of the beholder, whether in the human body, in a tree, in a landscape or in any other object. [from definition of BEAUTY in Noah Webster's "Dictionary of the English Language," 1828]

Formerly valued and hunted for its fur, which was used in the manufacture of hats, so much so that beaver could mean "hat" from 1520s and continued so into 19c. even after they began to be made of silk or other material. The gynecological sense ("female genitals, especially with a display of pubic hair") is 1927 British slang, perhaps transferred from earlier meaning "a bearded man" (1910), or directly from the appearance of split beaver pelts.

Meaning "change from one state of existence to another" is from 12c. Older sense preserved in what has become of it? It drove out Old English weorðan "to befall." Meaning "to look well, suit or be suitable to" is early 14c., from earlier sense of "to agree with, be fitting or proper" (early 13c.).
