The morphological structure of any language is directly related to the study of word composition and word structure. And the definition of the morphological structure of a language is the definition of the properties, internal meanings, and main features of a language in comparison with other languages. It is also closely related to the study of the modern synchronic structure of the language and the morphonematic features of its historical development. Morphemes as building materials of our language.The roots and bases in it, the derived words and other language units, form a subsystem. The morphological system is a collection of many grammatical categories, persons who are in opposition to each other. This means that the study of morphology on earth is the study of the basis, the construction of a language system. The article will focus on the historical development of morphological personalities in the works of Professor Marhabbat Tomanov.
