1818, "small house," from French maisonnette, diminutive of maison "house" (11c.), from Latin mansionem (see mansion). Meaning "a part of a building let separately" is by 1889.
You see, this is how it stands: I live in what the fellow who let the thing to me called a "maisonette"—goodness only knows why .... [Windsor Magazine, 1902]
"edible bivalve mollusk of the family Ostreidæ," late 13c., oistre, from Old French oistre, uistre (Modern French huître) and directly from Latin ostrea, plural or fem. of ostreum "oyster," from Greek ostreon, from PIE root *ost- "bone." It is thus related to Greek ostrakon "a hard shell" and to osteon "a bone." The h- in the modern French word is a regular development; compare huile "oil" (Latin oleum), huit "eight" (Latin octo).
Why then the world's mine Oyster, which I, with sword will open. [Shakespeare, "The Merry Wives of Windsor," II.ii.2]
Oyster-bed "place where oysters breed or are bred" is from c. 1600; oyster-knife, used for opening oysters, is recorded from 1690s. Oysterman "man engaged in rearing, taking, or selling oysters" is attested from 1550s. The common statement that edible oysters are in season only in months that end in -r is recorded by 1765.
Television is not impossible in theory. In practice it would be very costly without being capable of serious application. But we do not want that. On that day when it will be possible to accelerate our methods of telephotography by at least ten times, which does not appear to be impossible in the future, we shall arrive at television with a hundred telegraph wires. Then the problem of sight at a distance will without doubt cease to be a chimera. ["Telegraphing Pictures" in Windsor Magazine, vol. xxvi, June-November 1907]
Other proposals for the name of a then-hypothetical technology for sending pictures over distance were telephote (1880) and televista (1904). The technology was developed in the 1920s and '30s. Nativized in German as Fernsehen. Shortened form TV is from 1948. Meaning "a television set" is from 1941. Meaning "television as a medium" is from 1927.
Television is the first truly democratic culture — the first culture available to everyone and entirely governed by what the people want. The most terrifying thing is what people do want. [Clive Barnes, New York Times, Dec. 30, 1969]
mid-14c., gunne "an engine of war that throws rocks, arrows or other missiles from a tube by the force of explosive powder or other substance," apparently a shortening of woman's name Gunilda, found in Middle English gonnilde "cannon" and in an Anglo-Latin reference to a specific gun from a 1330 munitions inventory of Windsor Castle ("... una magna balista de cornu quae Domina Gunilda ..."). Also compare gonnilde gnoste "spark or flame used to fire a cannon" (early 14c.).
The identification of women with powerful weapons is common historically (such as Big Bertha, Brown Bess, Mons Meg, etc.).
Or perhaps gun is directly from Old Norse gunnr "battle." The word was perhaps influenced by or confirmed by (or possibly from) Old French engon, dialectal variant of engin "engine."
Meaning grew with technology, from cannons to firearms as they developed 15c.; popularly applied to pistols and revolvers from 1744. In modern military use the word is restricted to cannons (which must be mounted), especially long ones used for high velocity and long trajectory. Hence great guns (1884 as an exclamation) distinguished from small guns (such as muskets) from c. 1400. Meaning "thief, rascal" is from 1858. For son of a gun, see son. To jump the gun (1912, American English) is a figurative use from track and field. Guns "a woman's breasts" (especially if prominent) attested by 2006.
[G]un covers firearms from the heaviest naval or siege guns (but in technical use excluding mortars and howitzers) to the soldier's rifle or the sportsman's shotgun, and in current U.S. use even the gangster's revolver. In the other European languages there is no such comprehensive word, but different terms for the small or hand gun of the soldier or sportsman (even these, sometimes differentiated) and the heavy naval guns or artillery pieces ....
