This article analyses about nominative status of reduplicative words in English and Uzbek , Russian languages ,especially compound words and derivative words. Compound words are also characterized by semantic integrity. Turning to linguistic literature shows that there is no universally accepted definition of a compound word, that researchers use different criteria when defining the concept of a compound word; one is purely formal, the other is strictly semantic, the third is purely functional.

Keywords : Reduplication, Compound Words, Status, Semantic, Functional, Semantic Interaction.
