Abstract
In the article, genitive suffixes and noun phrases formed by the help of these suffixes have been examined. And the study has been based on the copies in Egypt, Kökşetav, İstanbul, St. Petersburg libraries and on the copy in the Turkish scientist Emel Esin’s private library. For this reason, the work has been published in Egypt, Kökşetav, Istanbul, St. Petersburg cities and copies of Turkish scientist Emel Esin's private library. First of all, the noun phrases that we encounter in the copies of "Diwan al-Hikmah" have been examined in two groups as the noun phrases formed according to the syntactic features of Persian and the noun phrases formed according to the syntactic features of Turkish. In addition, noun phrases established according to the syntactic features of Turkish have been examined separately as noun phrases in which genitive suffixes are used and noun phrases that do not use genitive suffixes. In addition, the formation and development processes of -nıŋ, -niŋ, -ıŋ, -iŋ, -ın, -in and -nı, -ni genitive suffixes in the Diwan al-Hikmah have been emphasized. In addition to this, the views of various Turcologists about the aforementioned suffixes were evaluated and discussed in the literature. In the next part of the article, the connection between the elements of the noun phrases and their meaning features have been examined. In particular, it has been discussed whether or not to use genitive suffixes in noun phrases and whether it has an effect on the meaning of the word group.
