The Old Uighur individual letters were among the manuscripts found in the Thousand Buddha Caves in Dunhuang. It is seen that the Old Uighur letters identified were written on the issues of human relations, work life, state administration, trade, agriculture and daily life. There are more than two hundred letters from the Buddhist, Manichaean and Christian surroundings. This study consists of reviewing and presenting the two titles in the doctoral dissertation we prepared on Old Uighur letters and announcing the updated results of the this part of the research. The vocabulary of the letters was compared with the vocabulary of Khakas through related studies and dictionaries and traceable (common) words were determined. In addition, the common Old Uighur and Khakassian words were evaluated according to Morris Swadesh's final 100-words list published in 1971. We can explain the reasons for this comparison by the fact that Khakas, which is in the azaq / taγlïγ group of Turkish dialects, together with Yellow Uighur and Fu-yu Kyrgyz, is one of the closest contemporary Turkish dialects to Old Uighur today, after Yellow Uighur, which is not a written language, and by requirement to describe this aspect of Old Uighur-Khakas language relations.

When it comes to etymology, two methods come to mind: 1. Scientific or linguistic etymology and 2. Folk etymology. However, the Polish linguist Marek Stachowski introduced a new etymology term to the literature: 3.”Perceptual etymology”. Stachowski explains the term, which he coined for the first time in his article titled “Perceptual etymology, or three Turkish culinary terms in Croatian and Slovene, and a Polish social term inteligencja ‘intelligentsia’” published in Studia Linguistica Universitatis Iagellonicae Cracoviensis 138 (4) in 2021, in his article titled “Perceptual etymology. A social aspect of etymological research” published in issue 139 (1) of the same journal in 2022. In this study; unaware of this new term, the origin information of which is explained, 'اِمْغا', 'اَلِمْغا' in the Diwanu Lugati’t-Turk of Kashgari (Barskani) Mahmud and the titles ‘amγa’, ‘il ïmγa’ in Old Uighur letter documents, which mean “guard of the military governor, secretary of state”, which have meanings such as “state treasurer, treasurer, tax collector”, are reconsidered in the context of the concept of “perceptual etymology”. Based on the previous sources, it is accepted that the word was borrowed from a Chinese title, yaya (押牙 / 押衙), from a Middle Chinese pronunciation of *im go dar to Turkish during the Chinese Tang Dynasty. This title is represented by Sir G. Clauson ‘ımğa’, T. Takata ‘ąmäga’, N. Sims-Williams and J. Hamilton ’’mγ’ (amγa) and T. Moriyasu as amγa / ïmγa. Here, the origin information of the title in question will be tried to be explained again through their spellings, historical developments and meanings in old Uighur documents and to be shown that the title is not borrowed into Turkish from Chinese, but from Khotanese Sakan.

In this study, the article titled "Török versek -Yunus Emréről, az Ómagyar Mária-siralom idejéből" ("Poems in Turkish -by Yunus Emre, from the time of the Mourning of the Virgin Mary in Old Hungarian") written by László Tusnády in the 5th (May) issue of the year 2019 of Búvópatak magazine with a civil, cultural and social content, which has been published monthly for 18 years in Hungarian, is the subject. Hungarian article is written between 15-19th pages of the journal, with two columns on each page. The sufi Turkish poet Yunus Emre, who lived in Anatolia in the 13th century, influenced not only the Turkish-Islamic world but also societies of different cultures and beliefs with his poems in which he spread the teaching of love. Tusnády's article is one of the best examples of this effect, written recently with the Christian Western understanding of the 21st century. Yunus Emre is a dervish-poet who seeks the divine essence in Anatolia, right in the middle of the intellectual resources and heritage of the East and the West. In his art, theology and philosophy merge. Here, it is explained how Tusnády, as a Western Christian but Hungarian writer, who speaks Turkish and is familiar with the Turkish-Islamic civilization, deals with Yunus Emre's mentality and influence on a universal scale, independent of space and time.
