The phrase "small feat" is an idiomatic expression that means a minor achievement or accomplishment. It refers to something that may seem insignificant, but it still requires effort and determination to complete. The term comes from the word "feat," which originally meant a remarkable deed or act of bravery, but over time has evolved to mean any notable action or accomplishment. When used in the negative (as in "small feat"), the phrase implies that what was accomplished is not particularly impressive or difficult.
