Erzyan language

The Erzya language (эрзянь кель, erzäny kel) is spoken by about 260,000 people in the northern and eastern and north-western parts of the Republic of Mordovia and adjacent regions of Nizhniy Novgorod, Chuvashia, Penza, Samara, Saratov, Orenburg, Ulyanovsk, Tatarstan and Bashkortostan in Russia. A diaspora can also be found in Armenia, Estonia as well as in Kazakhstan and other newly independent states of Central Asia. Erzya is currently written using Cyrillic with no modifications to the variant used by the Russian language. In Mordovia, Erzya is co-official with Moksha and Russian.

The language belongs to the Mordvinic branch of the Uralic languages. Erzya is closely related to Moksha, but is distinct in its phonetics, morphology and vocabulary.

Minimal pairs between /n/ and /ŋ/ include:

As in many other Uralic languages, Erzya has vowel harmony. Most roots contain either front vowels (/i/, /e/) or back vowels (/u/, /o/). In addition, all suffixes with mid vowels have two forms: the form to be used is determined by the final syllable of the stem. The low vowel (/a/), found in the comparative case -шка (ška) "the size of" and the prolative -ка/-га/-ва (ka/ga/va) "spatial multipoint used with verbs of motion as well as position" is a back vowel and not subject to vowel harmony.

The rules of vowel harmony are as follows:

However, if the back vowel is followed by a palatalized consonant or palatal glide, vowel harmony is violated and the "front" form of the suffix is used: кальсэ (kalʲse) "with willow", ойсэ (ojse) "with butter". Likewise, if a front-vowel stem is followed by a low back vowel suffix, subsequent syllables will contain back harmony: велеванзо (velʲevanzo) "throughout its villages"
