There are numerous regular sound correspondences between Hungarian and the other Uralic languages. For example, Hungarian á corresponds to Khantyo 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).
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 zero, here always preceding a long vowel, corresponds to Finnish and Estonian /k/ by itself (which may alternate with zero or /h/) and as the first member of a consonant cluster:
Two different regular correspondences can be found in Hungarian for Finnish and Estonian /s/. The first is Hungarian /s/:

These two correspondences represent two different original consonants. /s/ : /s/ is reconstructed as originating in Proto-Uralic *ś, while ∅ : /s/ 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.
