What does hopper mean?
A hopper is usually a container from which loose material is fed into a machine or processing system. Grain, coal, animal feed, and similar bulk substances may be stored in a hopper, allowing gravity or controlled mechanisms to move them onward. The word can also refer to a railway freight car built to transport loose material and unload it by tipping or through discharge gates. In a different, older or more playful sense, a hopper is a person or animal that hops, especially a grasshopper. In modern technical and industrial language, “hopper” primarily suggests a functional receptacle or loading device rather than a simple bucket. The term is especially common in agriculture, mining, manufacturing, and transport, where it names a component that holds or supplies material.
nounA hopper is a container or receptacle from which material such as grain, coal, or animal feed is discharged into a machine or onto a conveyor. The word can also refer to a person or animal that hops, especially a grasshopper, and to certain railway freight cars designed to discharge their contents.
- A container or receptacle that supplies material to a machine, often by gravity.
- A railway freight car that carries loose bulk material and can be unloaded by tipping or opening its discharge gates.
- A person or animal that hops, especially a grasshopper or similar insect.

"The grain hopper released a steady stream of wheat into the mill."
"The operator checked the feed hopper before starting the production line."
"A grasshopper landed on the rim of the empty hopper."
The plural is used for individual containers, freight cars, or hopping animals.
"The factory installed several new grain hoppers."
Before conveyors and modern loading systems, a hopper was often the simple gravity-fed gateway that moved loose material into machinery.

Where does hopper come from?
The word hopper developed from the verb “hop,” meaning to move with short jumps. Its older use for a hopping animal, particularly a grasshopper, reflects this straightforward relationship. The separate industrial sense developed from the idea of a vessel that lets its contents move or fall downward, much as a hopper or similar mechanism allows material to pass through it. The related word “hopscotch” also uses the older sense of hopping.
How hopper is actually used
In industrial contexts, “hopper” usually denotes a storage or feed receptacle and is typically treated as a piece of equipment. The sense meaning a grasshopper is less common in modern general usage but remains established.
