Samoyedic is one of the principal branches of the Uralic language family, and its ancestor is Proto-Uralic.
It has been suggested that Proto-Samoyedic greatly influenced the development of Tocharian, an Indo-European language.
Evidence of the vowel sequences has been preserved in only part of the Samoyedic languages, primarily in Nganasan and Enets.
Wagner-Nagy (2004)[4] lists the following examples: Proto-Samoyedic had vowel harmony like many other Uralic languages.
However, the restrictions imposed by vowel harmony were not absolute because also disharmonic word-stems can be reconstructed.
[5] Other widespread developments include prothesis of *ŋ, initial lenition of *p, and fortition of the semivowels *w, *j. Proto-Samoyedic was a fairly typical agglutinative language with only little morphophonological alteration, apart from vowel harmony.
Nouns distinguished seven cases: Verbs were conjugated for mood, tense, number and person.
