steely
UK: ˈstiːli | US: ˈstiːli
adj. resembling or characteristic of steel in color, hardness, or strength
adj. cold, harsh, or unyielding in manner or resolve
The word "steely" combines "steel," referring to the strong, durable alloy of iron and carbon, with the suffix "-y," which forms adjectives meaning "having the quality of." The term emerged in Middle English (as "steli") to describe literal steel-like properties, later extending metaphorically to describe rigid or unemotional traits. The suffix "-y" (from Old English "-ig") is a productive morpheme still used to create descriptive adjectives (e.g., "icy," "sunny").
