IPA: /ˈstiːli/
KK: /ˈstiːli/
Having a strong, hard, or cold quality, similar to steel; often used to describe someone's demeanor or appearance.
She had a steely determination to succeed, never backing down from a challenge.
Steely is derived from the word "steel" (from Old English "stæle", meaning a hard, strong metal) combined with the suffix "-y" (meaning characterized by or resembling). The word "steely" describes something that has the qualities or characteristics of steel, often implying strength or hardness.
Think of something that is 'characterized by' the strength of steel — that's why we use 'steely' to describe something strong or tough.
