In this study, the first thousand couplets in the khamsa of Ali Şir Nevayi in the 15th century were examined in terms of genitive-possessive construction chain. Nevayi, who developed the foundations of Chagatai literature and brought the Chagatai language to its peak, showed once again his superiority in writing ability and his sophesticated use of genitive-possessive construction chain structures he established in masnavis. The genitive-possessive construction chain is a controversial issue in Modern Turkish, linguists have discussed the issue in detail, and some of them, do not count it as part of possessive construction, consedering it uninteresting and unpleasant-sounding. Essentially, the genitive-possessive construction chain reveals a new meaning, showing the richness of the Turkish language and the diversity of it’s many expressive abilities. The fact that the genitive suffix is repeated or rarely dropped and connected with the next element in the same sentence, that other words are inserted between the genitive suffix, that the phrases of the genitive suffix are often composed of different lexical structures, and that Nevayi’s Chagatai genitive-possessive construction chain is an indicator of the rich aspects of the Turkish language. Acting with the genitive-possessive construction chain established by Nevayi; Repeating the relative suffix in the same sentence and connecting this suffix with the next element constitutes a genitive-possessive construction chain. As in Modern Turkish, there is a possibility that Nevayi's couplets can be a word or a word group that is a genitival or a determinatum in the structure of the genitive-possessive construction chain. Our study aims to examine the genitive-possessive construction chain structures found in the first thousand couplets of each masnavi in Ali Şir Nevayi’s khamsa.
