A distinct non-Indo-European family of Uralic languages (Estonian, Finnish, Hungarian, Erzya, Komi, Mari, Moksha, and Udmurt) is spoken mainly in Estonia, Finland,
Indo-Uralic languages in 1906 and another by H. Paasonen in 1908 (i.e. 1907) (ib.). Pedersen considered that these two studies sufficed to settle the question and that, after them, "it seems unnecessary to doubt the relationship further" (ib.).

Alwin Kloekhorst, author of the "Etymological Dictionary of the Hittite Inherited Lexicon", endorses the Indo-Uralic grouping
