Languages from this family were spoken in some nomadic tribal confederations, such as those of the Onogurs or Ogurs, Bulgars and Khazars.
The only other language which is conclusively proven to be Oghuric is the long-extinct Bulgar, while Khazar may be a possible relative within the group.
[14] There is no consensus among linguists on the relation between Oghuric and Common Turkic and several questions remain unsolved:[6] Fuzuli Bayat dates the separation into Oghur r-dialects and Oghuz z-dialects to the 2nd millennium BC.
[12] Chuvash: вăкăр - Turkish: öküz - Tatar: үгез - English: ox.
Hence the name Oghur corresponds to Oghuz "tribe" in Common Turkic.
[16][17] The shift from s to š operates before i, ï, and iV, and Dybo calls the sound change the "Bulgar palatalization".
[18] Denis Sinor believed that the differences noted above suggest that the Oghur-speaking tribes could not have originated in territories inhabited by speakers of Mongolic languages, given that Mongolian dialects feature the -z suffix.
[19] Peter Golden, however, has noted that there are many loanwords in Mongolic from Oghuric, such as Mongolic ikere, Oghuric *ikir, Hungarian iker, Common Turkic *ikiz 'twins',[6] and holds the contradictory view that the Oghur inhabited the borderlands of Mongolia prior to the 5th century.
*yüzük 'ring',[22] A number of Hungarian loanwords were borrowed before the 9th century, shown by sz- (< Oğ.
These loanwords were probably borrowed before the 4th century, before the Turkic migrations to West Asia happened.
