Club-footed describes a person whose foot — one or both — was twisted from birth, so it turns in and walking is hard without help or treatment. Doctors call the condition clubfoot. It is not from a fall, and it is not from joining a club. The “club” is about shape: the foot can look short and turned, a bit like a heavy stick. Many babies can be helped if care starts early. Use the word with care. It names a real body difference; it is not a joke about how someone walks, and it is not a word to throw at a classmate.
