"man who draws attention by unusual finery of dress and fastidiousness manners, a fop," c. 1780, of uncertain origin; attested earliest in a Scottish border ballad:
I've heard my granny crack
O' sixty twa years back
When there were sic a stock of Dandies O
etc. In that region, Dandy is diminutive of Andrew (as it was in Middle English generally). OED notes that the word was in vogue in London c. 1813-1819. His female counterpart was a dandizette (1821) with French-type ending.
Meaning "anything superlative or fine" is from 1786. As an adjective, "characteristic of a dandy, affectedly neat and trim," by 1813; earlier in the sense of "fine, splendid, first-rate" (1792) and in this sense it was very popular c. 1880-1900.
The popular guess, since at least 1827, is that it is from French Dandin, a mock surname for a foolish person used in 16c. by Rabelais (Perrin Dandin), also by Racine, La Fontaine, and Molière, from dandiner "to walk awkwardly, waddle." Farmer rejects this and derives it from dandyprat, an Elizabethan word for "a dwarf; a page; a young or insignificant person," originally (early 16c.) the name of a small silver coin. Both words are of unknown origin, and OED finds the connection of both to dandy to be "without any apparent ground." English dandy was itself borrowed into French c. 1830.
Jack-a-Dandy, or Jack O'Dandy figures in writings from the early 17c. He is listed among other famous Jacks in "Iack a Lent" (1620) and is sometimes defined as an impertinent little man, but other uses are unclear as to sense and in at least one instance from 1620s he is a bogeyman character.
DANDY was first applied half in admiration half in derision to a fop about the year 1816. John Bee (Slang Dict., 1823) says that Lord Petersham was the chief of these successors to the departed Macaronis, and gives, as their peculiarities, 'French gait, lispings, wrinkled foreheads, killing king's English, wearing immense plaited pantaloons, coat cut away, small waistcoat, cravat and chitterlings immense, hat small, hair frizzled and protruding.' [Farmer and Henley, "Slang and its Analogues," 1891]
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]
That pleasure which is at once the most intense, the most elevating, and the most pure is, I believe, found in the contemplation of the beautiful. When, indeed, men speak of Beauty, they mean, precisely, not a quality, as is supposed, but an effect—they refer, in short, just to that intense and pure elevation of soul—not of intellect, or of heart—upon which I have commented, and which is experienced in consequence of contemplating the “beautiful.” [Poe, "The Philosophy of Composition," 1846]
Old English tima "limited space of time," from Proto-Germanic *timon- "time" (source also of Old Norse timi "time, proper time," Swedish timme "an hour"), from PIE *di-mon-, suffixed form of root *da- "to divide."
Abstract sense of "time as an indefinite continuous duration" is recorded from late 14c. Personified at least since 1509 as an aged bald man (but with a forelock) carrying a scythe and an hour-glass. In English, a single word encompasses time as "extent" and "point" (French temps/fois, German zeit/mal) as well as "hour" (as in "what time is it?" compare French heure, German Uhr). Extended senses such as "occasion," "the right time," "leisure," or times (v.) "multiplied by" developed in Old and Middle English, probably as a natural outgrowth of such phrases as "He commends her a hundred times to God" (Old French La comande a Deu cent foiz).
to have a good time ( = a time of enjoyment) was common in Eng. from c 1520 to c 1688; it was app. retained in America, whence readopted in Britain in 19th c. [OED]
Time of day (now mainly preserved in negation, i.e. what someone won't give you if he doesn't like you) was a popular 17c. salutation (as in "Good time of day vnto your Royall Grace," "Richard III," I.iii.18), hence to give (one) the time of day "greet socially" (1590s); earlier was give good day (mid-14c.). The times "the current age" is from 1590s. Behind the times "old-fashioned" is recorded from 1831. Times as the name of a newspaper dates from 1788.
Time warp first attested 1954; time-traveling in the science fiction sense first recorded 1895 in H.G. Wells' "The Time Machine." Time capsule first recorded 1938, in reference to the one "deemed capable of resisting the effects of time for five thousand years preserving an account of universal achievements embedded in the grounds of the New York World's fair."
Jones [archaeologist of A.D. 5139] potters about for a while in the region which we have come to regard as New York, finds countless ruins, but little of interest to the historian except a calcified direction sheet to something called a "Time Capsule." Jones finds the capsule but cannot open it, and decides, after considerable prying at the lid, that it is merely evidence of an archaic tribal ceremony called a "publicity gag" of which he has already found many examples. [Princeton Alumni Weekly, April 14, 1939]
To do time "serve a prison sentence" is from 1865. Time frame is attested by 1964; time-limit is from 1880. About time, ironically for "long past due time," is recorded from 1920. To be on time is by 1854 in railroading.
