Regular sound correspondences between Hungarian and other Uralic languages

There are numerous regular sound correspondences between Hungarian and the other Uralic languages. For example, Hungarian á corresponds to Khanty o in certain positions, and Hungarian h corresponds to Khanty x, while Hungarian final z corresponds to Khanty final t. These can be seen in Hungarian ház ("house") and Khanty xot ("house"), or Hungarian száz ("hundred") and Khanty sot ("hundred").

Hungarian and Khanty are closely connected, either genealogically or as part of a language area. The distance between Hungarian and the Finnic languages is greater, but the correspondences are also regular. The relationship is most apparent when comparing all Uralic languages together, for then individual idiosyncrasies are averaged out, but in this article Hungarian is only compared with Finnish and Estonian (two Finnic languages).

Word-initially
One important innovation of Hungarian is the lenition of the stop consonants *p *k in initial position.


 * Hungarian corresponds to Finnish and Estonian  (compare English fish to Italian pesce via Grimm's law):


 * Before front vowels (e é i í y ä ö ő ü ű), Hungarian corresponds to Finnish and Estonian :


 * Before back vowels (a á o ó u ú), Hungarian corresponds to Finnish and Estonian  (as English  in hound corresponds to Latin  in canis)

The third stop inherited from Proto-Uralic, *t, did not undergo such a change.
 * Hungarian initial corresponds to Finnish and Estonian :

Word-medially
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 a different fashion.


 * Hungarian correspond to Finnish and Estonian geminate stops :

(No examples where a word with original *tt would have survived in both Hungarian and Finnic are known, but cases testifying for the development of *tt to /tt/ in Finnic and /t/ in Hungarian can be set up with the help of the other Uralic languages.)
 * Hungarian corresponds to the Finnish and Estonian two-stop cluster :


 * Hungarian corresponds to Finnish and Estonian  (which may alternate with ):

(Again, with the help of the other Uralic languages, the analogous developments *mp *ŋk → Hungarian /b g/, Finnic /mp ŋk/ could be supported.)


 * Hungarian corresponds to Finnish and Estonian :


 * Hungarian corresponds to Finnish and Estonian  (which can alternate with  or zero, and becomes  before ):


 * Hungarian zero, here always preceding a long vowel, corresponds to Finnish and Estonian by itself  (which may alternate with zero or /h/) and as the first member of a consonant cluster:

Sibilant consonants
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.

Sonorant consonants
Examples also include 'bit', 'to fear', 'cloud', 'fish', 'winter', 'flat', 'to push', 'bosom' listed above.
 * Hungarian liquid consonants correspond to Finnish and Estonian :

Further examples include 'honey', 'liver', 'eye',  'to plait', 'to see', 'sinew',  'tear', 'palate', 'arrow', 'to lick' listed above. Word-internally a correspondence Hungarian : Finnic  is also found, as seen in 'broth', 'name', and 'heart'.
 * Hungarian nasal consonants correspond to Finnish and Estonian :


 * A correspondence can also be set up between Hungarian and Finnish and Estonian long vowels. With the help of the other Uralic languages, this can be reconstructed as *ŋ:
