Mordvin languages at the beginning of the 20th century | |
The Mordvinic languages, also known as the Mordvin, Mordovian or Mordvinian languages (Russian: мордовские языки, romanized: mordovskiye yazyki), are a subgroup of the Uralic languages, comprising the closely related Erzya language and Moksha language, both spoken in Mordovia.
Previously considered a single "Mordvin language", it is now treated as a small language grouping. Due to differences in phonology, lexicon, and grammar, Erzya and Moksha are not mutually intelligible. The two Mordvinic languages also have separate literary forms. The Erzya literary language was created in 1922 and the Mokshan in 1923.

Traditionally, Uralicists grouped the Mordvinic and Mari languages together in the so-called Volgaic branch of the Uralic family; this view was however abandoned in the late 20th century. Instead, some Uralicists now prefer a rapid expansion model, with Mordvinic as one out of nine primary branches of Uralic; others propose a close relation between Mordvinic with the Finnic and Saamic branches of Uralic.
