engine

Engine started life in a very human place: the Latin idea of ingenium, “what you’re born with.” That’s the same family that gives us ingenious, genius, and even generate — all hung around the old notion of birth and making. In medieval France, engin could mean a clever trick or a siege machine, which makes perfect sense if you imagine a castle wall suddenly meeting a very determined battering ram. By 1300 English had borrowed the word, and by the 1800s steam turned engine into the hulking thing driving trains and factories. So the word’s history runs from inborn talent to iron machinery — a pretty wild commute.
