Etymology: Arcuballista is a Latin compound, formed from "arcus" (bow) and "ballista" (a large siege engine that hurled stones or bolts). Ballista itself comes from Greek "ballein," meaning "to throw." The name fits the device: it marries the bow-based tension of a crossbow to the frame and torsion-era thinking of the ballista. Medieval and Renaissance writers used the term, and it appears in discussions of late-medieval siege and arms technology, though the exact date and first attestation are uncertain. Because the word is a technical coinage built from two existing Latin parts, its meaning is transparent: a bow-and-ballista hybrid. Its use in English is largely confined to historians and writers on weaponry, and it is best read as a descriptive label rather than a long-established name for a single, standard device.
