Volgaic language
Finno-Volgaic language
Fenno-Volgaic language

However, it is also commonly used to mean the Finno-Permic languages, a hypothetical intermediate branch that includes Baltic Finnic, or the more disputed Finno-Volgaic languages.

The Mari language shows a smaller number of similarities with all three of these, and a larger grouping encompassing Finnic, Samic, Mordvinic and Mari is sometimes posited (the Finno-Volgaic languages).

In the traditional taxonomy of the Uralic languages, Finno-Permic is estimated to have split from Finno-Ugric around 3000-2500 BC, and branched into Permic languages and Finno-Volgaic languages around 2000 BC.
