To be pedantic, Finnish is not Ugric. Hungarian is Ugric, Finnish is Finnic. They both are Finno-Ugric, a.k.a Uralic. Many non-linguist Finns mix up Finno-Ugric and Ugric.

The Proto-Uralic *weti "water" looks like it could come from IE *u̯ódr̥, *udén- "water", but that etymology is problematic because of irregular sound substitutions[0]:

- why would Uralic have *e when it's not present in the IE original?

- why would Uralic drop *r or *n at the end?

A-ha, good to know. And sori on the "Ugric".

As for irregular sound substitutions, well, water IS a very common concept & word, so I would think that anything goes.
