stainless
UK: ˈsteɪnləs | US: ˈsteɪnləs
adj. resistant to staining, rust, or corrosion
adj. free from blemishes or moral impurity
n. (as "stainless steel") a type of steel alloy highly resistant to rust
The word "stainless" combines "stain" (from Old Norse steinn, meaning "mark" or "discoloration") with the suffix "-less" (Old English -lēas, meaning "without"). Originally, "stain" referred to physical marks or tarnishes, while "-less" negated it. By the 17th century, "stainless" described literal resistance to discoloration (e.g., fabrics), later extending metaphorically to moral purity. The technical term "stainless steel" (early 20th century) reinforced its association with durability.
