Comparison of Orkhon Turkic vocabulary with Oghuz dialects in terms of phonetics and morphology

In this study, in the first chapter, information about Orkhon Turkic and in the second chapter, information about Oghuz group dialects are given. In the third chapter, phonetics, which is one of our subjects of study, is included, information about the sounds used in dialects and examples of phonetic events in dialects are given. In the fourth chapter, morphology is discussed and information is given about the structure of words in Orkhon Turkic and dialects. In the fifth chapter, the words transferred from Orkhon Turkic to the Oghuz group were examined, and the changes these words experienced in dialects or their preserved forms were discussed. In the same dialect, a word or its cognate may preserve its sound characteristics or show different sound characteristics. In this regard, all words showing these features were evaluated and examined separately under the headings of phonology and morphology. Words that have undergone sound changes or preserved their sound characteristics are given directly, and words whose cognates are given are shown in square brackets. In the conclusion section, the number of words in Orkhon Turkic in the Oghuz group dialects is given in numbers and graphs. Finally, a general evaluation was made. In the appendices section, the list of words that preserve their phonetic features, undergo phonetic changes and have only cognate forms is given. In addition, the list of words that are not found in any dialect is also included.
