An ethnonym (Gk.ethnos, 'tribe', + onuma, 'name') is the name of an ethnic group, whether that name has been assigned by another group (ie. an exonym), or self-assigned (ie. an autonym). Greek (Greek Îλληνικά, IPA â Hellenic) is an Indo-European language with a documented history of 3,500 years. ... An exonym is an ethnonym assigned to one set of people by a different set of people, which the first set do not use to refer to themselves. ...
An older Chinese rendering of this autonym is Yáohuer.
The Turkic speaking Western Yugur's autonym is Yoghïr or Sarïgh Yoghïr (sarïgh yellow, Yoghïr Yugur), that of the Mongolic speaking Eastern Yugur is Yoghor or Shera Yoghor (shera yellow, Yoghor Yugur).
It remains to be investigated why and how the Turkic and Mongolic speaking Yugur came to use the same autonym.
