stainless-steel
UK: ˈsteɪnləs stiːl | US: ˈsteɪnləs stil
n. a type of steel alloy resistant to rust and corrosion, containing chromium and other elements
The word combines "stain" (from Old Norse steinn, meaning "discoloration") + "-less" (Old English -lēas, meaning "without") + "steel" (Old English stȳle, from Proto-Germanic stahliją). The term emerged in the early 20th century to describe chromium-alloyed steel that resists staining (rust). The logic is straightforward: "steel that lacks staining."
