- catapult:  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’.
