The Greek roots

βάλλειν
bállein
to throw, hurl

Literally: having to do with throwing

The story of the word

The Roman ballista, a torsion catapult, took its name from Greek βάλλειν, to throw. That verb is also behind problem, symbol and devil, since a διάβολος is one who throws accusations across. Going ballistic is much later slang, from a missile that has burnt its fuel and is now merely falling.
