hopper

The word 'hopper' is a straightforward agent noun formation from the verb 'hop', which has deep Germanic roots. The Old English verb hoppian is related to similar words in other Germanic languages, all conveying the idea of a short, springing leap. By adding the agent suffix -er, the word originally denoted a person or creature that hops, such as a dancer or a grasshopper. This literal sense was then logically extended to mechanical devices that exhibit a similar jerking or bouncing motion, most notably the funnel-shaped container that allows grain or other materials to "hop" or be dispensed in a controlled manner into a machine below.
