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.
