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
Indo-Uralic languages central contention, agreeing with Rédei's views, is that all of the lexical items claimed to be Indo-Uralic can be explained as loans from Indo-European into Uralic (see below for examples). The most common arguments in favour of a relationship between Indo-European and Uralic are based on seemingly common elements of morphology, such as the pronominal roots ("*m-" for first person; "*t-" for second person; "*i-" for third person), case markings (accusative "*-m"; ablative/partitive "*-ta"), interrogative/relative pronouns ("*kʷ-" "who?, which?"; "*y-" "who, which" to signal relative clauses) and a common SOV word order. Other, less obvious correspondences are suggested, such as
