Fallacies of definition are the various ways in which definitions can fail to explain terms. The phrase is used to suggest an analogy with an informal fallacy.[1] Definitions may fail to have merit, because they are overly broad,[2][3][4] overly narrow,[3][4] or incomprehensible;[4] or they use obscure or ambiguous language,[2] contain mutually exclusive parts,[3] or (perhaps most commonly[5]) are circular.[2][6]
