Vās (n.), vāsis, keeps s throughout plural vās, vāsōrum. In the other cases the stem assumes the form niv- and it adds i in the genitive plural.Į. In nix, nivis the nominative retains a g from the original stem, the g uniting with s, the nominative ending, to form x. Hence it shows forms of both the 4th and 2nd declensions.

In the stem bov- ( bou-) the diphthong ou becomes ō in the nominative ( bōs, bŏvi).
