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',
Indo-Uralic languages borrowed between them, most often from Indo-European languages into Uralic ones. An example of a Uralic word that cannot be original is Finno-Ugric *"śata" "hundred". The Proto-Indo-European form of this word was *"ḱm̥tóm" (compare Latin "centum"), which became *"ćatám" in early Indo-Iranian (reanalyzed as the neuter nominative–accusative singular of an "a" stem > Sanskrit "śatá-", Avestan "sata-"). This is evidence that the word was borrowed into Finno-Ugric from Indo-Iranian or Indo-Aryan. This borrowing may have occurred in the region north of the Pontic-Caspian steppes around 2100–1800 BC, the approximate floruit of Indo-Iranian (Anthony 2007:371–411). It provides linguistic evidence for the
