"excavating equipment consisting of a digging bucket on the end of an articulated arm, typically mounted on the back of a tractor," by 1928, from back (n. or adj.) + hoe (n.).

also getup, 1847, "equipment, costume," from get (v.) + up (adv.). Meaning "initiative, energy" recorded from 1841. The verbal phrase is recorded from mid-14c. as "to rise."

"traveling equipment," c. 1600, from Latin impedimenta "luggage, military baggage," literally "hindrances," on the notion of "that by which one is impeded;" plural of impedimentum "hindrance" (see impediment).

commercial word-forming element denoting devices that work automatically or businesses containing self-service equipment, abstracted from automat (1903), which probably is from automatic, in which case the element is etymologically from Greek matos "thinking, animated."

1570s, from French équipage (15c.), from équiper "to fit out" (see equip). Now largely replaced by equipment. In 18c. often especially tweezers, a toothpick, earpick, nail-cleaner, etc., carried on the person in a small case.

also re-tool, 1866, "to shape again with a tool," from re- "back, again" + tool (v.). Meaning "to furnish a factory with new equipment" is recorded from 1940. Related: Retooled; retooling.

children's game, 1801 (from 1789 as hop-scot), apparently from hop (v.) + scotch (n.2) "scratch," from the lines scored in the dirt to make the squares for the game.

"one that reacts," 1835, agent noun in Latin form from react. By 1915 in electricity as "coil or other piece of equipment which provides reactance in a circuit;" the nuclear sense is attested from 1945.

card game, 1864, from German Skat (by 1838), from earlier scart (said to have been a term used in the old card game taroc, which was of Italian origin), from Italian scarto "cards laid aside," which is said to be a back-formation from scartare, from Latin ex- "off, away" + Late Latin carta (see card (n.1)). The German game is perhaps so called because it is played with a rump deck, or because two cards are laid aside at the start of the game, or because discarding is an important part of the game. Compare the French card game écarté, literally "cards removed."

1900, as Ping-Pong, trademark for table tennis equipment (Parker Brothers). Both words are imitative of the sound of the ball hitting a hard surface; from ping + pong (attested from 1823). It had a "phenomenal vogue" in U.S. c. 1900-1905.
