1819, "wheeled vehicle propelled by alternate thrusts of each foot on the ground," 1819, from French vélocipède (19c.), from Latin velox (genitive velocis) "swift, speedy" (see velocity) + pedem, accusative of pes "foot" (from PIE root *ped- "foot"). The mechanical ancestor of the bicycle, it was tinkered with and improved; the name continued for some time and was applied to an early kind of modern bicycle or tricycle from 1849. See bicycle (n.).
The Velocipede has been introduced into England, under letters patent, by Mr. Johnson, a coachmaker in Long-Acre, by whom it has been greatly improved, both in lightness and strength. "The road from Ipswich to Whitton," says the Bury paper, "is travelled every evening by several pedestrian hobby-horses; no less than six are seen at a time, and the distance, which is 3 miles, is performed in 15 minutes." [The Athenaeum, May 1, 1819]
"style of architecture and decoration which prevailed in Europe late 17c. through much of 18c., later derided as clumsy in form and extravagant in contorted ornamentation," 1765, from French baroque "irregular" (15c.), said to be from Portuguese barroco "imperfect pearl," which is of uncertain origin, perhaps related to Spanish berruca "a wart."
This style in decorations got the epithet of Barroque taste, derived from a word signifying pearls and teeth of unequal size. [Fuseli's translation of Winkelmann, 1765]
The Spanish word is perhaps from Latin verruca "a steep place, a height," hence "a wart," also "an excrescence on a precious stone" (see verruca). But Klein suggests the name may be from Italian painter Federico Barocci (1528-1612), whose work influenced the style. How to tell baroque from rococo, according to Fowler: "The characteristics of baroque are grandeur, pomposity, and weight; those of rococo are inconsequence, grace, and lightness." But the two terms have been used without distinction for styles featuring odd and excessive ornamentation.
late 14c., "upper regions of space," from Old French ether (12c.) and directly from Latin aether "the upper pure, bright air; sky, firmament," from Greek aithēr "upper air; bright, purer air; the sky" (opposed to aēr "the lower air"), from aithein "to burn, shine," from PIE *aidh- "to burn" (see edifice).
In ancient cosmology, the element that filled all space beyond the sphere of the moon, constituting the substance of the stars and planets. Conceived of as a purer form of fire or air, or as a fifth element. From 17c.-19c., it was the scientific word for an assumed "frame of reference" for forces in the universe, perhaps without material properties. The concept was shaken by the Michelson-Morley experiment (1887) and discarded early 20c. after the Theory of Relativity won acceptance, but before it went it gave rise to the colloquial use of ether for "the radio" (1899).
The name also was bestowed c. 1730 (Frobenius; in English by 1757) on a volatile chemical compound known since 14c. for its lightness and lack of color (its anesthetic properties weren't fully established until 1842).
c. 1300, fairie, "the country or home of supernatural or legendary creatures; fairyland," also "something incredible or fictitious," from Old French faerie "land of fairies, meeting of fairies; enchantment, magic, witchcraft, sorcery" (12c.), from fae "fay," from Latin fata "the Fates," plural of fatum "that which is ordained; destiny, fate," from PIE root *bha- (2) "to speak, tell, say." Also compare fate (n.), also fay.
In ordinary use an elf differs from a fairy only in generally seeming young, and being more often mischievous. [Century Dictionary]
But that was before Tolkien. As a type of supernatural being from late 14c. [contra Tolkien; for example "This maketh that ther been no fairyes" in "Wife of Bath's Tale"], perhaps via intermediate forms such as fairie knight "supernatural or legendary knight" (c. 1300), as in Spenser, where faeries are heroic and human-sized. As a name for the diminutive winged beings in children's stories from early 17c.
Yet I suspect that this flower-and-butterfly minuteness was also a product of "rationalization," which transformed the glamour of Elfland into mere finesse, and invisibility into a fragility that could hide in a cowslip or shrink behind a blade of grass. It seems to become fashionable soon after the great voyages had begun to make the world seem too narrow to hold both men and elves; when the magic land of Hy Breasail in the West had become the mere Brazils, the land of red-dye-wood. [J.R.R. Tolkien, "On Fairy-Stories," 1947]
Hence, figurative adjective use in reference to lightness, fineness, delicacy. Slang meaning "effeminate male homosexual" is recorded by 1895. Fairy ring, of certain fungi in grass fields (as we would explain it now), is from 1590s. Fairy godmother attested from 1820. Fossil Cretaceous sea urchins found on the English downlands were called fairy loaves, and a book from 1787 reports that "country people" in England called the stones of the old Roman roads fairy pavements.
