Etymologies

Middle English engin, skill, machine, from Old French, innate ability, from Latin ingenium; see genə- in Indo-European roots.
(American Heritage® Dictionary of the English Language, Fourth Edition)
From Middle English engin, from Old French engin ("skill", "cleverness", "war machine"), from Latin ingenium ("innate or natural quality, nature, genius, a genious, an invention, in Late Latin a war-engine, battering-ram"), from ingenitum, past participle of ingignere ("to instil by birth, implant, produce in"); see ingenious. Engine originally meant 'ingenuity, cunning' which eventually developed into meaning 'the product of ingenuity, a plot or snare' and 'tool, weapon'. (Wiktionary)
