Özet:

It is a known fact that there is a direct relationship between the life and the thinking system of the society that uses it in writing and verbal. The social life of the peoples and the thinking system appear as two concepts that progress parallel to each other. Based on the relationship between language and mind, the formation of words in the brain has been studied by researchers. The mental process of the language occurs from different stages. The first stage of this process is the perception. It sends the events around the human being to the brain by sensing them. In the second phase, it performs understanding and interpretation of the information that is received and the information that is in the brain. Finally, the individual expresses his own thoughts and feelings by moving from this information. This process shows the direct relationship between mind and language very clearly. It has always been a question of how the periodic use of Turkish is experienced today by linguists. This study has been conducted from the work called Codex Cumanicus and the mental facts used in the Kuman-Kıpçak field, which is an important field of Turkish, have been discovered and the state of the mental facts used in Turkish during this period has been attempted to be identified in today's Anadolu mouths.
