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 particle. Similarities have long been noted between the verb conjugation systems of Uralic languages (e.g. that of Finnish) and Indo-European languages (e.g. those of Latin, Russian, and Lithuanian). Although it would not be uncommon for a language to borrow heavily from the vocabulary of another language (as in the cases of English from French, Persian from Arabic, and Korean from Chinese), it would be extremely unusual for a language to borrow its basic system of verb conjugation from another. Supporters of the existence of Indo-Uralic have thus used morphological arguments to support the Indo-Uralic thesis by, for example, arguing that
