A feat is an exemplary, even bold achievement, often an act of great courage or skill. Getting your cat to wear a leash was quite a feat.
The noun feat developed from the Latin facere, meaning "make do." Today, it gets applied to a deed that's noble or out of the ordinary. Have you ever accomplished amazing feats in your dreams, like flying? If so, I hope you didn't wake up on the roof. Maybe you perform feats of daring in your everyday life, if you're a firefighter or a tightrope walker. If you're afraid of heights, just taking the glass elevator counts as a courageous feat!
