Regular sound correspondences between Hungarian and other Uralic languages The relationship is most obvious when comparing all Uralic languages together, for then individual idiosyncrasies are averaged out, but here we will just compare Hungarian with Finnish and Estonian (two Finnic languages). One important innovation of Hungarian is the lenition of the stop consonants *p *k in initial position. The third stop inherited from Proto-Uralic, *t, did not undergo such a change. In the middle of words (note that due to the loss of the word final vocals in the Old Hungarian period these are now at the end of the words), Hungarian has also lenited original stops, but in
Uralic–Yukaghir languages linguistic science may yet be able to resolve some of these seemingly intractable issues (cf. Vajda 2008). Häkkinen (2012) rejects a genetic link between Uralic and Yukaghir, arguing that the grammatical systems show too few convincing resemblances, especially the morphology, and proposes instead that many apparent Uralic–Yukaghir cognates are really borrowed from an early stage of Uralic (ca. 3000 BC; he dates Proto-Uralic at ca. 2000 BC) into an early stage of Yukaghir, while Uralic was (according to him) spoken near the Sayan region and Yukaghir near the Upper Lena River and near Lake Baikal. Aikio (2014) agrees that Uralic–Yukaghir
