Sweet considered the relationship to be securely established, stating (1900:120; "Aryan" = Indo-European, "Ugrian" = Finno-Ugric): Björn Collinder, author of the "Comparative Grammar of the Uralic Languages" (1960), a standard work in the field of Uralic studies, argued for the kinship of Uralic and Indo-European (1934, 1954, 1965). Alwin Kloekhorst, author of the "Etymological Dictionary of the Hittite Inherited Lexicon", endorses the Indo-Uralic grouping
