내리다 spreads across several senses, and these lines show most of them: getting off a vehicle (두 정거장을 가서 내려서 'ride two stops and get off'), lowering something (엄지손가락을 들어서 내릴까? 'thumb up, then down?'), bringing a fever down (열이 너무 많이 나서 내리고 싶을 때), and the one that catches learners out — 결정을 내리다 'make a decision': 혼자 생각해서 내린 결정 'a decision she reached on her own'.
