ballistics

Etymology

The OED takes it as borrowed from New Latin ballistica, recorded in 1644 in the title of a work by Mersenne, the noun use of the feminine of ballisticus (“ballistic”),^[2][1] which is formed from Latin ballista and the suffix -icus.^[2] Barnhart and Etymonline instead take it as formed in English from the Latin ballista and the suffix -ics, as in physics and athletics.^[3][4] The Latin ballista, an ancient engine of war for hurling stones and other missiles,^[3][4][5] is from Greek,^[3][4][1] and goes back to Ancient Greek βάλλω (bállō, “to throw”),^[1][4][5] from Proto-Indo-European *gwele- (“to throw, reach”).^[4] The OED compares French balistique, recorded from 1647.^[2] The adjective ballistic came later, from 1775 in Etymonline.^[4][2]

Earliest recorded meaning

The science of the motion of projectiles, and especially of their action and effects: 1675, in the Philosophical Transactions of the Royal Society.^[2] Merriam-Webster Unabridged also gives 1675,^[6] and the Oxford Dictionary of Word Origins the late 17th century,^[5] while Barnhart and Etymonline date the word to 1753, in Chambers's Cyclopaedia.^[3][4]

Semantic evolution

The word first named the art of throwing large missiles and the science of the flight of projectiles,^[4][2] and came to centre on firearms.^[7][6] From 1880 the science was split into exterior ballistics, the flight of a projectile after it leaves the gun, and interior ballistics, its motion inside the weapon,^[2][8] terms that follow French balistique extérieure and German äussere Ballistik.^[2] From 1965 ballistics was also the department of a police force that examines bullets and firearms, or such an examination;^[2] since 1989 it has also meant the missiles, bullets or debris thrown through the air themselves.^[2] The adjective ballistic became widely known in the mid-20th century with the ballistic missile, and in the 1980s to go ballistic came to mean to fly into a rage.^[5][4]
