Mamluk Kipchak Turkish forms two branches of the Historical Kipchak dialect together with Northern Kipchak Turkish. This dialect, which became a written language with the establishment of the Mamluk (Kölemen) State, developed as a standardized written language and was replaced by the Oghuz dialect by the 16th century. Dictionaries, grammars, and works in various subjects, particularly the art of warfare, were written in this dialect when Kipchak Turkish was established as the standard writing system in Egypt and Syria. These works include some that exhibit the distinctive features of Kipchak Turkish as well as some that mix Kipchak and Oguz dialects. This study analyzes a necessary conjugation that appears in various texts. The necessitative is a modal that expresses the necessity of carrying out the work, action, or occurrence. This mood is categorized as one of the subjunctives in grammars. The necessitative in Mamluk Kipchak Turkish is typically created using words known as modal words. Moreover, the necessary mood created by the suffix can be found. This study examines the kErek(dür)...verb-(G)A(y)+(personal pronouns/affixes) structure used in Kipchak Turkish-language literature. Examples of the structure were gathered after all works published during this time period were scanned. The abbreviations of the works as well as the page and line numbers from which the examples were obtained are provided in parentheses. The examples taken from the works are presented in plain text format. The example is then translated into Turkish and italicized. It was observed that there is no unity in the use of the word kerek/ kirek/ kerekdür and the suffix -(G)A(y) in the structure of the modal. For example, in Münyetü'l-Guzât, it is possible to see both kerek and kirek in the same sentence. Although there is no standard among the works, it is possible to say that the works are consistent in this regard. It is also observed that the suffix -(G)A(y) attached to the verb in conjugation takes different forms. The -ke form of this suffix is found in one example. With the influence of the Oghuz dialect, the suffix -(G)A(y) is also seen to be suffixed in the form of -A The analysis resulted in the discovery that, with the exception of the first person plural, all other people have examples of this mood. The majority of the examples, it has been observed, are in the third person singular. The functions of the mood are also examined, and examples of conjugation according to the persons are provided individually. The study is concluded with a part in which the findings are discussed.
