air (n.1)[air 词源字典]: c. 1300, "invisible gases that make up the atmosphere," from Old French air "atmosphere, breeze, weather" (12c.), from Latin aerem (nominative aer) "air, lower atmosphere, sky," from Greek aer (genitive aeros) "air" (related to aenai "to blow, breathe"), which is of unknown origin, possibly from a base *awer- and thus related to aeirein "to raise" and arteria "windpipe, artery" (see aorta) on notion of "lifting, that which rises." In Homer mostly "thick air, mist;" later "air" as one of the four elements.

Words for "air" in Indo-European languages tend to be associated with wind, brightness, sky. In English, air replaced native lyft, luft (see loft (n.)). To be in the air "in general awareness" is from 1875; up in the air "uncertain, doubtful" is from 1752. To build castles in the air is from 1590s (in 17c. English had airmonger "one preoccupied with visionary projects"). Broadcasting sense (as in on the air) first recorded 1927. To give (someone) the air "dismiss" is from 1900. Air pollution is attested by 1870.[air etymology, air origin, 英语词源]
California: name of an imaginary realm in "Las sergas de Esplandián" ("Exploits of Espladán"), a romance by Spanish writer Garci Ordóñez de Montalvo, published in 1510. It was a sequel to his "Amadis de Gaula," and was said to have been influential among Spanish explorers of the New World. It could have led them to misidentify Baja California as this mythical land and to mistake it for an island. The Amadis tales are the Iberian equivalent of the Arthurian romances; they are older than 1510 (traces of them have been found mid-14c.) and were wildly popular. That conquistadors and sailors would have known the story in all its imaginative detail is hardly surprising.
Amadis de Gaula ... set a fashion: all later Spanish writers of books of chivalry adopted the machinery of Amadis de Gaula. Later knights were not less brave (they could not be braver than) Amadis; heroines were not less lovely (they could not be lovelier) than Oriana; there was nothing for it but to make the dragons more appalling, the giants larger, the wizards craftier, the magic castles more inaccessible, the enchanted lakes deeper. Subsequent books of chivalry are simple variants of the types in Amadis de Gaula: Cervantes made his barber describe it as 'the best of all books of this kind.' This verdict is essentially just. Amadis de Gaula was read everywhere, especially in the French version of Herberay des Essarts. It was done into Hebrew during the sixteenth century, and attracted readers as different as St Ignatius of Loyola and Henry of Navarre. Its vogue perhaps somewhat exceeded its merit, but its merits are not inconsiderable. [James Fitzmaurice-Kelly, "Spanish Literature," 1922 edition]
Where Montalvo got the name and what it means, if anything, is a mystery. Californian is attested from 1785. The element Californium (1950) was named in reference to University of California, where it was discovered.
castle (n.): late Old English castel "village" (this sense from a biblical usage in Vulgar Latin); later "large fortified building, stronghold," in this sense from Old North French castel (Old French chastel, 12c.; Modern French château), from Latin castellum "a castle, fort, citadel, stronghold; fortified village," diminutive of castrum "fort," from Proto-Italic *kastro- "part, share;" cognate with Old Irish cather, Welsh caer "town" (and perhaps related to castrare via notion of "cut off;" see caste). In early bibles, castle was used to translate Greek kome "village."

This word also had come to Old English as ceaster and formed the -caster and -chester in place names. Spanish alcazar "castle" is from Arabic al-qasr, from Latin castrum. Castles in Spain translates 14c. French chastel en Espaigne (the imaginary castles sometimes stood in Brie, Asia, or Albania) and probably reflects the hopes of landless knights to establish themselves abroad. The statement that an (English) man's home is his castle is from 16c.
Frankenstein (n.): allusive use for man-made monsters dates to 1838, from Baron Frankenstein, character in Mary Shelley's 1818 novel "Frankenstein: The Modern Prometheus." Commonly taken (mistakenly) as the proper name of the monster, not the creator, and thus franken- extended 1990s as a prefix to mean "non-natural." The German surname is probably literally "Franconian Mountain," stein being used especially for steep, rocky peaks, which in the Rhineland often were crowned with castles. The Shelleys might have passed one in their travels. The German surname also suggests "free stone."
Frankenstein is the creator-victim; the creature-despot & fatal creation is Frankenstein's monster. The blunder is very common indeed -- almost, but surely not quite, sanctioned by custom. [Fowler]
Jew (n.): late 12c. (in plural, giwis), from Anglo-French iuw, Old French giu, from Latin Iudaeum (nominative Iudaeus), from Greek Ioudaios, from Aramaic jehudhai (Hebrew y'hudi) "Jew," from Y'hudah "Judah," literally "celebrated," name of Jacob's fourth son and of the tribe descended from him. Replaced Old English Iudeas "the Jews." Originally, "Hebrew of the kingdom of Judah."

Jews' harp "simple mouth harp" is from 1580s, earlier Jews' trump (1540s); the connection with Jewishness is obscure. Jew-baiting first recorded 1853, in reference to German Judenhetze. In uneducated times, inexplicable ancient artifacts were credited to Jews, based on the biblical chronology of history: such as Jews' money (1570s) "Roman coins found in England." In Greece, after Christianity had erased the memory of classical glory, ruins of pagan temples were called "Jews' castles," and in Cornwall, Jews' houses was the name for the remains of ancient tin-smelting works.
redcap (n.): "porter at a railroad station," 1914, American English, from red (adj.1) + cap (n.). Earlier it was the name of the goldfinch, a type of hen, and a long-toothed spectre in Scottish castles.
