Finno-Ugric or Fenno-Ugric is a group of languages in the Uralic language family, comprising the Finno-Permic and Ugric language families.
Proto-Finno-Ugric is the reconstructed protolanguage for the Finno-Ugric languages, i.e., the ancestor of all Uralic languages except for the Samoyedic languages. Its reconstructed parent language is Proto-Uralic, which split into Proto-Finno-Ugric and Proto-Samoyedic. This classification is not without problems; Proto-Finno-Ugric may be interpreted as a geographical grouping instead of a genetic grouping because the differences are few. It has been suggested that the area where Proto-Finno-Ugric was spoken reached between the Baltic Sea and the Ural mountains.
