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',
Finnic languages harmony (lost in Livonian, generally also in Estonian and Veps) is also an important process. Historically, the "erosion" of word-final sounds (strongest in Livonian, Võro and Estonian) may leave a phonemic status to the morphophonological variations caused by the agglutination of the lost suffixes, which results in three phonemic lengths in these languages. The original Uralic palatalization was lost in proto-Finnic, but most of the diverging dialects reacquired it. Palatalization is a part of the Estonian literary language and is an essential feature in Võro, as well as Veps, Karelian, and other eastern Finnic languages. It is also found in
