industrial-strength

The compound "industrial-strength" is a modern English formation, originating in the 20th century as a marketing and technical term. It literally combines "industrial," pertaining to the scale and demands of manufacturing, with "strength," denoting power and durability. The term's logic is straightforward: a product labeled as such possesses the robustness required for rigorous industrial applications, implying it surpasses ordinary or domestic standards. Through metaphorical extension, this literal meaning evolved into a common informal usage to describe anything exceptionally potent or intense, from coffee to arguments, leveraging the cultural association of industrial-grade materials with superior performance.

In this compound, it functions as an adjective meaning "of or relating to industry or manufacture." - strength: From Old English strengþu, strengþo ("power, force, vigour"), derived from strang ("strong"). It functions as a noun meaning "the quality or state of being strong."
