1888 as the name of a theater in Boston; by 1909 as "a motion picture theater," from nickel "five-cent coin" (the cost to view one) + -odeon, as in Melodeon (1840) "music hall," ultimately from Greek oideion "building for musical performances" (see odeon). Meaning "nickel jukebox" is first attested 1938.
The nickelodeon is the poor man's theater. An entire family can obtain from it a whole evening's amusement for what it formerly cost to get one poor seat at an inferior production. ["The Moving-Picture Show" in Munsey's Magazine, 1909]
"a picture obtained by any process of photography," 1839, coined by English polymath and photography pioneer Sir John Herschel (son of the astronomer) from photo- "light" + -graph "something written."
It won out over other suggestions, such as photogene and heliograph. Photogram (1859), based on telegram, did not catch on. Neo-Anglo-Saxonists prefer sunprint; and sun-picture (1846) was an early Englishing of the word. The verb is first found (along with photography and photographic) in a paper Herschel read before the Royal Society on March 14, 1839. Related: Photographed; photographing.
also jig-saw, vertical reciprocating saw, 1855, American English, from jig with its notion of "rapid up-and-down motion" + saw (n.1). It was largely displaced by the later band-saws. Jigsaw puzzle first recorded 1906; originally one with pieces cut by a jigsaw. Earlier was dissected map (or picture), 1807, "map or picture mounted on board and divided into more or less irregular parts, to be joined together as a puzzle."
