catapult

catapult: [16] The first catapults were large military machines for hurling missiles at the enemy (originally darts, in contrast with the ballista, which discharged large rocks, but the distinction did not last); the schoolboy’s handheld catapult, consisting of a piece of elastic fixed in a Y-shaped frame, did not appear until the latter part of the 19th century. Etymologically, their name is a fairly straightforward description of what they do: it comes ultimately from Greek katapáltēs, which was formed from katá- ‘down’, hence ‘against’, and pállein ‘hurl’.

catapult (n.)

1570s, from Middle French catapulte and directly from Latin catapulta "war machine for throwing," from Greek katapeltes, from kata "against" (see cata-) + base of pallein "to toss, hurl" (see pulse (n.1)). As an airplane-launching device on an aircraft-carrier by 1927.

catapult (v.)

1848, "to throw with a catapult," from catapult (n.). Intransitive sense by 1928. Related: Catapulted; catapulting.
