阿尔泰语系
A major continuing supporter of the Altaic hypothesis has been S. Starostin, who published a comparative lexical analysis of the Altaic languages in (1991). He concluded that the analysis supported the Altaic grouping, although it was "older than most other language families in Eurasia, such as Indo-European or Finno-Ugric, and this is the reason why the modern Altaic languages preserve few common elements".
