Wikipedia definition
2. ReduplicationReduplication in linguistics is a morphological process in which the root or stem of a word (or part of it) is repeated exactly or with a slight change. Reduplication is used in inflections to convey a grammatical function, such as plurality, intensification, etc. , and in lexical derivation to create new words. It is often used when a speaker adopts a tone more "expressive" or figurative than ordinary speech and is also often, but not exclusively, iconic in meaning.
