Mordvinic languages

The Mordvinic languages, alternatively Mordvin languages, or Mordvinian languages (, Mordovskiye yazyki, the official Russian term for the language pair), are a subgroup of the Uralic languages, comprising the closely related Erzya language and Moksha language. Previously considered a single "Mordvin language", it is now treated as a small language family. Due to differences in phonology, lexicon, and grammar, Erzya and Moksha are not mutually intelligible, to the extent that the Russian language is often used for intergroup communications.
