power-plant

The compound noun "power-plant" is a modern industrial term formed by combining two English words of distinct origins. "Power" traces back to the Latin verb posse, meaning "to be able," which evolved through Old French to signify force, strength, and the capacity to do work. "Plant," from the Latin planta meaning a sprout or shoot, broadened in English to describe something that has been planted or established, eventually referring to heavy machinery and the buildings housing industrial processes. The logic of the compound is transparently literal: a "plant" (industrial facility) dedicated to the generation of "power" (electrical energy). This reflects a 19th/20th-century pattern of naming large-scale industrial complexes by their primary function.
