Özet:

The Epic of Oğuz Kağan, written in the Uyghur alphabet, is a very special text in terms of Turkish mythology, history and grammar with the material it presents and has been the subject of separate examination in terms of these areas. Although the inferences about the period and field in which the work was written point to the post-Islamic era, the fiction, mythological and cosmogonic elements in the epic, and the relationship established between Oğuz Kağan and Mete Han, a historical figure, point to the core fiction of the text, which was shaped before Islam. It is known that epics, which were organized and enriched around historical events and heroes in the Turkish epic tradition, were founded in a very old time and maintained their existence thanks to oral culture until the period when they were written down. In the sentence Kök böri bolsungıl uran in the Epic of Oğuz Kağan, the +gIl suffix appears in an unprecedented usage. In common grammatical studies, it is seen that this suffix is evaluated with the function of reinforcing the imperative expression for the second person, and with reference to Indo-European languages, the suffix is attributed the feature of enclitic, intensifying preposition, and intensifying suffix. It will be discussed with examples taken from historical texts that the +gIl suffix is not used to meet the second person and to indicate reinforcement in the text in question, it will be explained in the light of the suffixation system that this suffix is a plural suffix, and it will be revealed that it is also used as a plural suffix in the Oğuz Kağan Epic.
