Rouran language
Rouran, also called Ruanruan, Ruan-ruan or Juan-juan, is an unclassified extinct language of Mongolia and Inner Mongolia, spoken in the Rouran Khaganate from the 4th to the 6th centuries AD, The Rouran state was undoubtedly multi-ethnic, but there is no definite evidence as to their language. The received view is that the relationships of the language remain a puzzle. Vovin through the analysis of the Brāhmī Bugut and Khüis Tolgoi consider it a likely early precursor to Mongolic. According to Alexander Savelyev and Choongwon Jeong the identification of Brāhmī Bugut and Khüis Tolgoi with the Rouran language remains problematic because of the dating. They further write According to Vovin, the Brāhmī Bugut inscription is dated to ca. 584–587 AD, and the Khüis Tolgoi inscription must have been erected between 604 and 620 AD. As both were created several decades after the Rouran Khaganate had been destroyed, it is unsafe to make conclusions on the composition of the Rouran population, or its elite, on the basis of these inscriptions.
Peter A. Boodberg claimed in 1935 that the Rouran language was Mongolic by analysing Chinese transcriptions of Rouran names. Atwood notes that Rourans calqued the Sogdian word pūr "son" into their language as *kobun ; which, according to Atwood, is cognate with Middle Mongol kö'ün "son". Alexander Vovin noted that Old Turkic had borrowed some words from an unknown language not part of the Altaic sprachbund that might have been Rouran, arguing that if so, the language would be possibly a language isolate, though evidence was scant. In 2019, with the emergence of new evidence through the analysis of the Brāhmī Bugut and Khüis Tolgoi, Vovin changed his view, suggesting Rouran was, in fact, a Mongolic language, close but not identical to Middle Mongolian.
