This article explores the grammatical, semantic, and expressive possibilities of reduplication, focusing on its role in Uzbek and other languages. Reduplication, a widespread morphological and syntactic phenomenon, serves as a multifunctional linguistic tool that intensifies meaning, marks plurality, adds emotional nuance, and structures discourse. The study analyzes various types of reduplications—from full and partial lexical-semantic repetition to syntactic parallelism—and illustrates their functions with examples from English, Uzbek, and other languages. Particular attention is given to the significance of reduplication in poetry, oral tradition, and everyday communication, highlighting its stylistic and rhetorical impact.
The research also discusses the development of morphological analysis modules and linguistic software tailored for Uzbek, emphasizing the necessity of incorporating reduplicative forms for accurate automatic text processing, stemming, and lemmatization. The findings underscore the typological importance of reduplication, which varies according to language typology and morphology, and distinguishes it clearly from simple word repetition due to its semantic and morphosyntactic complexity.
