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 languages grammatical and phonological features, in particular the similarities in the Uralic and Altaic pronouns and the presence of agglutination in both sets of languages, as well as vowel harmony in some. For example, the word for "language" is similar in Estonian ("keel") and Mongolian ("хэл" ("hel")). These theories are now generally rejected and most such similarities are attributed to language contact or coincidence. Nostratic associates Uralic, Indo-European, Altaic, Dravidian, and various other language families of Asia. The Nostratic hypothesis was first propounded by Holger Pedersen in 1903 and subsequently revived by Vladislav Illich-Svitych and Aharon Dolgopolsky in the 1960s. Eurasiatic
