Alwin Kloekhorst, author of the "Etymological Dictionary of the Hittite Inherited Lexicon", endorses the Indo-Uralic grouping (2008b). He argues that, when features differ between the Anatolian languages (including Hittite) and the other Indo-European languages, comparisons with Uralic can help to establish which group has the more archaic forms (2008b: 88) and that, conversely, the success of such comparisons helps to establish the Indo-Uralic thesis (2008b: 94). For example, in Anatolian the nominative singular of the second person pronoun comes from *"ti(H)", whereas in the non-Anatolian languages it comes from *"tu(H)"; in Proto-Uralic it was *"ti", which agrees with evidence from internal reconstruction that Anatolian has the more archaic form (2008b: 93).
