Origin & History of “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 hand-held 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’.
