Regular sound correspondences between Hungarian and other Uralic languages a different fashion. (Again, with the help of the other Uralic languages, the analogous developments *mp *ŋk → Hungarian /b g/, Finnic /mp ŋk/ could be supported.) Two different regular correspondences can be found in Hungarian for Finnish and Estonian . The first is Hungarian : The second is Hungarian zero: These two correspondences represent two different original consonants. : is reconstructed as originating in Proto-Uralic *ś, while ∅ : is reconstructed as Proto-Uralic *s. Both correspondences can be seen simultaneously in the word for "autumn" (see above under *-k-), from Proto-Uralic *sükśi. Examples also include 'bit', 'to fear', 'cloud',
Uralic–Yukaghir languages has vaguely implied the existence of a Uralic–Yukaghir genetic node, and in this he seems to have been followed by Ruhlen and Greenberg, followed in turn by Bomhard. The actual relations of these languages remain to be scrutinized in detail. No work of synthesis of a definitive nature has appeared on this subject. As in several other cases of this sort (see Ural–Altaic languages), that Uralic and Yukaghir are related has been argued for in some detail, but how they are related remains uncertain. It is therefore not surprising that, at the present time (2009), the validity of the Uralic–Yukaghir
