Occurrence of Transposition and Substantivization Phenomena Between Adjectival and Noun Word Categories in Uzbek

This study investigates the phenomena of transposition and substantivization between adjectival and noun word categories in the Uzbek language, an area that remains underexplored in linguistic research. By analyzing selected texts, the study identifies shifts where adjectives become nouns (substantivization) and nouns assume adjectival roles (transposition), focusing on their contextual usage in proverbs, literary works, and everyday speech. The research identifies 150 instances of these shifts, demonstrating the flexibility and dynamic nature of word categories in Uzbek. The findings provide new insights into language evolution and structural adaptability, with broader implications for understanding the linguistic characteristics of Turkic languages.
