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 World's Languages" by Merritt Ruhlen (1987). Uralic and Yukaghir are listed as a language family, forming a subgroup of a higher-order family called "Eurasiatic", in Joseph Greenberg's "Indo-European and Its Closest Relatives" (2000–2002). However, Greenberg did not present a discursive argument for this subgroup, presumably leaving it to the reader to work it out from the data on grammar and vocabulary he presented. The Uralic–Yukaghir family has been accepted by the American Nostraticist Allan Bomhard (2008:176, citing Ruhlen 1987:64–65) but without presenting any argument for it, and Russian linguist Vladimir Napolskikh. Collinder summarizes his case for, not merely a relationship
