This article explores the unique grammatical structure of faleronyms in the Uzbek language. Faleronyms, composed of words, syntactic units, and grammatical tools, exhibit a strict order and distinct functional roles. Nouns are the primary active elements, while adjectives, numerals, and verbs act as auxiliary components. The use of grammatical affixes is limited, with noun-specific markers such as possessive, case, and plural affixes playing a crucial role. Particular attention is given to the instrumental case and possessive affixes, whose definite and indefinite forms in faleronyms reflect specific stylistic and semantic features. The study highlights the adaptive formation of noun+noun constructions, expressing attribution and ownership, and emphasizes the repeated and regulated use of affixes in complex faleronyms. Overall, the findings demonstrate that possessive affixes serve as essential grammatical markers, shaping the structure and meaning of faleronyms while ensuring clarity and stylistic precision in formal contexts.
