When the word Yue (Middle Chinese: ɦʉɐt̚) was borrowed into Vietnamese language during late Tang dynasty (618–907) by the Austroasiatic Viet-Muong speaking peoples who were the ancestors of modern-day Vietnamese Kinh, the exonym was gradually localized to become an endonym of the Vietnamese. That endonym might have been manifested in different forms depending on how neighboring peoples who interact with, referred to the Vietnamese back then, and till modern-day, for instance, the Cham have been calling the Vietnamese as Yuen (yvan) from the reign of Harivarman IV (1074–1080) to present unchanged. It is evident that Vietnamese elites tried to tie their ethnic identity to the ancient Yue through constructed traditions during the late medieval period. However, all endonyms and exonyms referring to the Vietnamese such as Viet, Kinh, or Kra–Dai Keeu, are related to political structures or have common origins in ancient Chinese geographical imagination. Most of the time, the Austroasiatic-speaking ancestors of the modern Kinh under one single ruler might have assumed for themselves a similar or identical self-designation inherent in the modern Vietnamese first-person pronoun ta (us, we, I) to differentiate themselves with other groups. In the older colloquial usage, ta corresponded to "ours" as opposed to "theirs", and during colonial time they were "nước ta" (our country) and "tiếng ta" (our language) in contrast to "nước tây" (western countries) and "tiếng tây" (western languages).
