Abstract
This article presents a comprehensive phono-morpho-semantic analysis of mood forms in the language of the «Diwani Hikmet»monument, which belongs to thelegacy of the prominent 11th-century Sufi poet Khoja Ahmed Yasawi. The paper explores the specific features of the mood category in Turkic written monuments and its historical development, while also tracing the continuity between ancient and modern formsof mood in the Kazakh language.In Old Turkic texts, the mood category is regarded as an essential means of expressing the possibility of an action and the speaker's attitude toward it. Based on concrete linguistic material from the hikmets, the usage andtransformation of imperative, optative, and conditional moods are analyzed, alongside a typological comparison with modern Kazakh. The main objective of the article is to reveal the developmental process of mood forms in the grammatical system of «Diwani Hikmet»and to determine their place and evolution in the Old Turkic language. The research findings demonstrate that mood forms in the language of «Diwani Hikmet»are not only grammatical in nature but also convey semantic meanings linked to Sufi thought.This study contributes to the fields of historical grammar, Old Turkic manuscript studies, and the understanding of the development stages of the Kazakh language.
