Antagonyms, Contronyms or Auto-antonyms

Words that have conflicting definitions

Many words have several definitions, like bill.  But in some cases those definitions are conflicting.  With bill, for example, in one instance it refers to a debt and in another an asset.  These are called auto-antonyms.  (They are also called “contronyms,” “antagonyms,” “self-antonyms,” “self-contradicting words,” and “janus words.”)
