Ethnonym
An ethnonym (from Ancient Greek ἔθνος (éthnos) 'nation' and ὄνομα (ónoma) 'name') is a name applied to a given ethnic group. Ethnonyms can be divided into two categories: exonyms (whose name of the ethnic group has been created by another group of people) and autonyms, or endonyms (whose name is created and used by the ethnic group itself).
