I hate to be that guy, but you're thinking about endonyms and eponyms. From http://en.wikipedia.org/wiki/Exonym_and_endonym http://en.wikipedia.org/wiki/Exonym_and_endonym: The United Nations Group of Experts on Geographical Names defines: Endonym: Name of a geographical feature in an official or well-established language occurring in that area where the feature is located. Exonym: Name used in a specific language for a geographical feature situated outside the area where that language is spoken, and differing in its form from the name used in an official or well-established language of that area where the geographical feature is located.[2] For example, China, India and Germany are the English exonyms corresponding to the endonyms Zhongguo, Bharat and Deutschland, respectively.
