Endonym and exonym
An endonym or autonym is a common, self-chosen, native name of a group of people, an individual person of that group, a geographical place, a language or a dialect; it is 'native' in the sense that it is used inside or by a particular group or linguistic community to identify or designate themselves, their place of origin, or their language. An exonym or xenonym is a foreign-established, non-native name for a group of people, an individual person of that group, a geographical place, a language, or a dialect, meaning that it is used primarily outside the particular place inhabited by the group or linguistic community.
