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',
Proto-Uralic language Proto-Uralic was an agglutinative nominative–accusative language. Proto-Uralic nouns are reconstructed with at least six noun cases and three numbers, singular, dual and plural. Grammatical gender was not recognized and no Uralic language does so even today. Noun articles were unknown. The plural marker of nouns was *"-t" in final position and *"-j-" in non-final position, as seen in Finnish "talot" and "talojen" ("house" Pl.Nom and Pl.Gen). The dual marker has been reconstructed as *"-k-", but the dual number has been lost in many of the contemporary Uralic languages. The cases were: The cases had only one three-way locative contrast of
