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. Exonyms exist not only for historico-geographical reasons but also in consideration of difficulties when pronouncing foreign words, or from non-systematic or failed attempts to properly and faithfully transcribe and translate local-originated names into different writing systems. For instance, Deutschland is the endonym for the country that is also known by the exonyms Germany and Germania (in English and Italian, respectively), Alemania and Allemagne (in Spanish and French, respectively), Niemcy (in Polish), and Saksa and Saksamaa (in Finnish and Estonian, respectively).
