Etymology

Origin of hopper

Middle English word dating back to 1200–50; see origin at hop ¹, -er ¹

Explanation

A hopper is a funnel-shaped device used to move material from one receptacle to another. This type of hopper has nothing to do with hopping or jumping: it's a device — the kind you're most likely to see in a chemistry lab — for moving substances from one container to another. If you need to pour a large beaker of liquid into a tiny test tube, the hopper lets you move the liquid without spilling. Solid, grain-like substances could also be moved using a hopper. Many factories will have hoppers as part of their machinery too.
