wacky words of the day

defenestration
1620, "the action of throwing out of a window," from L. fenestra "window." A word invented for one incident: the "Defenestration of Prague," May 21, 1618, when two Catholic deputies to the Bohemian national assembly and a secretary were tossed out the window (into a moat) of the castle of Hradshin by Protestant radicals. It marked the start of the Thirty Years War. Some linguists link fenestra with Gk. verb phainein "to show;" others see in it an Etruscan borrowing, based on the suffix -(s)tra, as in L. loan-words aplustre "the carved stern of a ship with its ornaments," genista "the plant broom," lanista "trainer of gladiators."

malapropism
1849, from Mrs. Malaprop, character in Sheridan's play "The Rivals" (1775), noted for her ridiculous misuse of large words (i.e. "contagious countries" for "contiguous countries"), her name coined from malapropos (adv.), 1668, a borrowing from Fr. mal à propos "inopportunely, inappropriately," lit. "badly for the purpose," from mal (see mal-) + proposer "propose."

gossip (this one has a weird origin)
O.E. godsibb "godparent," from God + sibb "relative" (sibling). Extended in M.E. to "any familiar acquaintance" (1362), especially to woman friends invited to attend a birth, later to "anyone engaging in familiar or idle talk" (1566). Sense extended 1811 to "trifling talk, groundless rumor." The verb meaning "to talk idly about the affairs of others" is from 1627.
