condom (n.): 1706, traditionally named for a British physician during reign of Charles II (a story traceable to 1709), but there is no evidence for that. Also spelled condam, quondam, which suggests it may be from Italian guantone, from guanto "a glove." A word omitted in the original OED (c. 1890) and not used openly in the U.S. and not advertised in mass media until November 1986 speech by Surgeon General C. Everett Koop on AIDS prevention. Compare prophylactic.
demote (v.): 1881, American English coinage from de- + stem of promote. Said to have been Midwestern in origin.
Regarding an antithesis to 'promote,' the word universally in use in Cambridge, in Harvard College, is drop. The same word is in use in the leading schools here (Boston). I hope I may be counted every time against such barbarisms as 'demote' and 'retromote.' [Edward Everett Hale, 1892, letter to the publishers of "Funk & Wagnalls' Standard Dictionary"]
Related: Demoted; demoting.
fourth estate (n.): "the press," by 1824, and especially from 1831, British English. For the other three, see estate. Earlier the term had been applied in various senses that did not stick, including "the mob" (1752), "the lawyers" (1825). The extension to the press is perhaps an outgrowth of the former.
Hence, through the light of letters and the liberty of the press, public opinion has risen to the rank of a fourth estate in our constitution; in times of quiet and order, silent and still, but in the collisions of the different branches of our government, deciding as an umpire with unbounded authority. ["Memoir of James Currie, M.D.," 1831]

[Newspapers] began to assume some degree of political importance, during the civil wars of the seventeenth century, in England; but it is not until within the last fifty years that they have become, -- as they are now justly styled, -- a Fourth Estate, exercising a more powerful influence on the public affairs of the countries in which they are permitted to circulate freely, than the other three put together. [Alexander H. Everett, "Address to the Phi Beta Kappa Society of Bowdoin College," 1834]
Gettysburg: town in south-central Pennsylvania, U.S., 1800 (earlier it was Gettys-town), founded 1780s by Gen. James Gettys and named for him. Civil War battle there was fought July 1-3, 1863. The Gettysburg Address was given Nov. 19, 1863, and was being called that by 1865, though before President Lincoln's assassination the term tended to refer to Edward Everett's full oration that preceded Lincoln's short speech.
Pre-Raphaelite (n., adj.): c. 1848, in reference to the "brotherhood" (founded 1847) of Holman Hunt, Dante Gabriel Rossetti, John Everett Millais, and others (seven in all) who, encouraged by Ruskin, sought to revive the naturalistic spirit of art in the age before Raphael Sanzio (1483-1520).
