Middle English (formerly also as ingine ): from Old French engin , from Latin ingenium talent, device, from in- in + gignere beget; compare with ingenious . The original sense was ingenuity, cunning (surviving in Scots as ingine ), hence the product of ingenuity, a plot or snare , also tool, weapon , later specifically denoting a large mechanical weapon; which led to the sense a machine (mid 17th cent.), used commonly later in combinations such as steam engine , internal-combustion engine .
