"The dancer's graceful leap was a feat of such dexterity that it left the audience breathless."
In plain English: A feat is an adjective used to describe something that was very difficult but managed successfully, though it is more commonly used as a noun for the achievement itself rather than describing things directly.
"That was no easy feat to climb that mountain without any gear."
Usage: Use this archaic adjective only when describing someone's dexterity with their hands, as it is rarely found in modern speech compared to the more common noun "feat." Avoid using it for general skill unless you are intentionally writing in a historical or literary style.
The word "feat" comes from the Latin factum, meaning "deed," which entered English through Anglo-Norman and Middle English. It is a doublet of the word "fact."
