ballistic

Etymology

The OED takes it as borrowed from New Latin ballisticus, recorded in 1644 in “Phenomena ballistica”, the title of a section of Mersenne's “Cogitata physico-mathematica”, and formed with the suffix -icus on the classical Latin name of the war engine.^[2][2] Most other dictionaries derive it directly from ballista with the English suffix -ic.^{[3][4][5][6][7]} The OED compares French balistique, recorded in 1649, then spelled “ballistique”, in a French translation of Mersenne's work.^[2] That noun, ballista, a machine for hurling stones, comes from Ancient Greek βαλλιστής (ballistḗs),^[2][8] from βαλλίζω (ballízō, “to throw projectiles”), from βάλλω (bállō, “to throw”).^[2][9][10] The OED calls the Greek verb of uncertain origin;^[2] Etymonline traces it to Proto-Indo-European *gwele- (“to throw, reach”),^[8] and Klein compares βολή (bolḗ, “a throw”) and βέλος (bélos, “bolt, arrow, dart”).^[9]

Earliest recorded meaning

Relating to the throwing and flight of missiles, especially bullets fired from guns: 1764, in a heading in the General Magazine of Arts and Sciences.^[2] Merriam-Webster gives the same year for the sense "of the hurling of missiles",^[6] while Etymonline dates the adjective to 1775,^[8] and Dictionary.com to 1765–75.^[7]

Semantic evolution

The adjective stayed a technical word for most of its history: from 1843 it described motion that follows the laws of ballistics, under gravity, inertia and air resistance alone.^[2] Physiologists used it from 1905 of a movement begun by a quick muscle contraction and carried on by momentum.^[2] In American use from 1896 ballistic armour or material was made to stop bullets.^[2] Etymonline dates its use of rockets and missiles that are guided only while under power and then fall freely to 1949, and ballistic missile to 1954.^[8] Such missiles climb to great heights, which Etymonline sees behind the figurative phrase go ballistic, to become wildly angry.^[8] The OED records the figurative sense "out of control, berserk" from 1981, in R. Scruton's “Fortnight's Anger”,^[2][8] and Green's Dictionary of Slang, which marks the phrase as originally American, quotes the New York Times in 1988.^[11]
