The issue of Ogur-Oghuz            

       Ogurs are brothers of Oghuzes. Probably because they separated from each other in very early periods (before 3rd Century B.C.), there occurred some phonetical differences in their languages. The most definite difference is that the "Z" sound in main Turkish was turned into "R" in Ogur dialect. In fact, since "Oghuz" term meant "Turkish clans" directly, the following difference in the names of Oghuzes, the main mass who remained in the east and continued to use Z sound and Ogurs (western Turks) attracts attention: Oguz-Ogur. The Ogur clan unions above meant successively: 5 Oghuz, 6 Oghuz, 9 Oghuz, 10 Oghuz and 30 Oghuz.

 

        As a matter of fact there are some unions named with the number of clans in Eastern Turks. Another difference in Ogur dialect is that y is replaced with d (for example: yilan-dilom etc.) Ancient Greek Geographer Ptolemaios (160 -170) stated the name of Yayik river discharged to Caspian Sea (Today's Ural river, the real Turkish name was changed by Russians in the 2nd half of 18th century) as Daih (aix), which documents that the ancestors of Bulgarians lived in Western Siberia in 2nd century in steppes as far as Itıl (Volga).
