Etymology
the term "pump-action" is a modern compound originating in the late 19th to early 20th century, specifically describing firearm technology. it directly borrows the word "pump" from its mechanical context, evoking the back-and-forth motion used to draw water, to describe the manual sliding of the fore-end on a shotgun or rifle. the word "action" derives from the latin agere (to drive, do), and in firearms terminology, it denotes the mechanism that handles ammunition. thus, the compound literally and logically describes a firearm whose core operating mechanism is a manually driven, pump-like sliding motion.
