On some grammatical features of doubling in linguistics

This article reveals the general grammatical properties of reduplication in linguistics. The concept of “reduplication” (from lat. “Reduplikatio” - “doubling”) today does not have a clear and general definition for all researchers. In different interpretations under this concept the unequal circle of the phenomena-from a set of intraverbal to a set of interverbal doublings is brought. The most common structural types of reduplication are represented in different languages in one form or another. In all languages (or in most languages), reduplication can be complete (complete doubling of the reduplicant in the reduplicator) and divergent (with a change in the sound composition of the reduplicant). Along with the universal structural-semantic manifestations of reduplication, different languages are characterized by a peculiar interpretation of general, invariant structural types of intraword doubling and general, invariant semantics. As our observations show, being few in each particular language, the most productive models of reduplication generally coincide in languages with the same morphological structure. At the same time, differently structured languages show clear differences in this respect. In isolating and agglutinative languages that use the agglutinative technique in word construction, reduplication occurs within the root morpheme. In Slavic languages with synthetic inflectional order, synonymous suffixes and prefix morphemes are predominantly duplicated. With significant similarities in structural models of reduplication, languages of the same morphological type also have differences in this respect, although very slight. Such discrepancies mainly concern the productivity, unproductiveness of some structural models within the same onomasiological classes.
