Origin and history of engine

engine(n.)

c. 1300, "mechanical device," especially one used in war; "manner of construction," also "skill, craft, innate ability; deceitfulness, trickery," from Old French engin "skill, wit, cleverness," also "trick, deceit, stratagem; war machine" (12c.), from Latin ingenium "innate qualities, ability; inborn character," in Late Latin "a war engine, battering ram" (Tertullian, Isidore of Seville). This is etymologically "that which is inborn," from in- "in" (from PIE root *en "in") + gignere "to beget, produce" (from PIE root *gene- "give birth, beget").

The sense of "device that converts energy to mechanical power" emerged in 18c. In 19c. the word was used especially of steam engines. Middle English also had ingeny (n.) "gadget, apparatus, device," directly from Latin ingenium.

mid-14c., enginour, "constructor of military engines," from Old French engigneor "engineer, architect, maker of war-engines; schemer" (12c.), from Late Latin ingeniare (see engine).

The general sense of "inventor, designer" is recorded from early 15c.; the non-military sense, in reference to public works, is recorded from c. 1600 but was not the common meaning of the word until 19c (hence lingering distinction as civil engineer). The meaning "locomotive driver" is attested by 1832, American English. A "maker of engines" in ancient Greece was a mekhanopoios.

1680s, "engine designed to throw a stream of water through a hose onto a fire for the purpose of extinguishing it," from fire (n.) + engine (n.). Also an early name for a steam engine (1722).
