Word Formation by Reduplication Method in Modern Turkic Languages

. There are examples of grammaticalisation in various forms in Turkic languages. Reduplication attracts attention both as a grammatical sign and as one of the ways of word formation. Repetition is one of the grammatical categories functionally used in Turkic languages. This article examines examples from old and modern Turkic languages. It explains with examples that the method of reduplication is used in Turkish as a method of word formation, as in some other world languages. In addition, some language units formed by repetition are tried to explain by the theory of grammar and are dealt with from examples in which reduplication creates the inflectional features in semantic and morphological categories. The method of reduplication in languages where it is used as a grammatical sign, grammatical categories such as augmentative, limitation, frequency, transition, etc., can be mentioned by forms with different phonological values, such as full or partial reduplication. The reduplication formed by the repetition of a word in the first stage represents the intermediate stage before the completion of word formation in the second stage. It is a semantic description of the newly formed word. There are many lexical units in the orthographic dictionary of the Azerbaijani language, which are words formed by the method of reduplication. The reproduction process is less productive than morphological, syntactic, lexical and other word-formation methods. Still, as a result, there is such a method in the grammatical structure of Turkic languages.
