Uralic languages the loss of *x and alteration of *ï. Finnish has even preserved old Indo-European borrowings relatively unchanged as well. (An example is "porsas" ("pig"), loaned from Proto-Indo-European "*porḱos" or pre-Proto-Indo-Iranian "*porśos", unchanged since loaning save for loss of palatalization, *ś > s.) The Estonian philologist Mall Hellam proposed cognate sentences that she asserted to be mutually intelligible among the three most widely spoken Uralic languages: Finnish, Estonian, and Hungarian: However, linguist Geoffrey Pullum reports that neither Finns nor Hungarians could understand the other language's version of the sentence. No Uralic language has exactly the idealized typological profile of the family.
Uralic languages resembles Nostratic in including Uralic, Indo-European, and Altaic, but differs from it in excluding the South Caucasian languages, Dravidian, and Afroasiatic and including Chukotko-Kamchatkan, Nivkh, Ainu, and Eskimo–Aleut. It was propounded by Joseph Greenberg in 2000–2002. Similar ideas had earlier been expressed by Heinrich Koppelmann in 1933 and by Björn Collinder in 1965. The hypothesis that the Dravidian languages display similarities with the Uralic language group, suggesting a prolonged period of contact in the past, is popular amongst Dravidian linguists and has been supported by a number of scholars, including Robert Caldwell, Thomas Burrow, Kamil Zvelebil, and Mikhail Andronov.
