Usage notes
A homophone is a type of homonym in the loose sense of that term (a word which sounds or is spelled the same as another). (The strict sense of homonym is a word that both sounds and is spelled the same as another word.) A homograph is a word with the same spelling as another but a completely unrelated meaning. Homographs are not necessarily homophones.
