Origin of engine

  • Middle English engin skill, machine from Old French innate ability from Latin ingenium genə- in Indo-European roots

    From American Heritage Dictionary of the English Language, 5th Edition

  • From Anglo-Norman engine, Old French engin (“skill, cleverness, war machine”), from Latin ingenium (“innate or natural quality, nature, genius, a genius, an invention, in Late Latin a war-engine, battering-ram”), from ingenitum, past participle of ingignere (“to instil by birth, implant, produce in”). Compare gin, ingenious.
