ON THE BASIS OF SOME FORMULATIONS OF PERSIAN ASSIMILATION USED IN THE OLD UZBEK LANGUAGE: THE IRANIAN LAYER IN THE FORMATIVE PARTS OF COMPOUND WORDS IN THE GHAZALS OF ALISHER NAVOI

This study examines Persian assimilations in Old Uzbek (Chagatai Turkic), focusing on compound word formations in Alisher Navoi’s ghazals where at least one formative element derives from the Iranian (Persian-Tajik) layer. Drawing on historical linguistics and textual analysis of Navoi’s *Ghazaliyat* and *Khazoyin ul-maoniy*, the article analyzes izafa constructions and hybrid compounds as mechanisms of lexical and syntactic integration. It incorporates quotations from language history theory and evaluates the role of assimilated vocabulary in Uzbek. Results demonstrate that Persian formative elements enriched Navoi’s poetic diction, enabling nuanced expression of love, mysticism, and philosophy. The discussion underscores assimilation’s contribution to Uzbek’s lexical depth while preserving Turkic structures. This IMRAD-structured analysis highlights bilingual literary traditions in Timurid Central Asia and their enduring impact on modern Uzbek philology.
