The subject of this research is the toponyms Yessentuk, Yessentuchok, Yessentuki. The goal is ti determine their origin. The author leans on the data of explorations of the remains Golden Horde mausoleums of the XIV century, which were conducted in the late XX and early XXI centuries on the outskirts and in the area of the city of Yessentuki of Stavropol Krai. The article considers the previously revealed connection between mausoleums of the XIV century, Podkumok River Valley, and the Kabardian-Abazin tombstones of the XVIII century located here. It is worth noting that at the time of construction of the Yessentuki reduit at the end of the XVIII century, the general population of the area were Kabardians and Abazins. The application of comprehensive approach alongside various methods of historical and philological sciences allowed determining the origins of the toponyms Yessentuk, Yessentuchok, Yessentuki, as well as carrying out further reconstruction of the history of the Central Fore-Caucasus of pre-Russian and Russian eras. The conclusion is made that the name Yessentuk (in later versions – Yessentuchok and Yessentuki) stems from the Kabardian word combination Yesen tlygu – the edge, area, or border) of Yesen. The personal name Yesen is of Turkic-Mongolian origin and can be occasionally seen in the anthroponymy of the Adyghe and neighboring peoples. The obtained results can be used in studying history of the North Caucasus, toponymic research, museology, creation of science education films.
