The history of the studying word building in the Mordovian languages

Introduction. The article provides an overview of research regarding word building in the Mordovian languages. The purpose of the study is to highlight the history of the study of word building in the Mordovian languages, and to analyze the works of D. V. Tsygankin, who made a significant contribution to the study of Mordovian derivatology, to the formation of the principles of its teaching and analysis. Materials and Methods. The material of the research is based on word building in the Mordovian languages. The work was performed using descriptive, comparative and historical-typological methods. Results and Discussion. Word building is considered a new research area. In Russia its formation is associated with the name of M. V. Lomonosov. In the design of word building as a academic branch in the 19th century the main role belongs to representatives of four scientific schools in Russia: in Moscow, Kharkov, Kazan and Petersburg. Word building has been considered as an independent object of study only since the mid–1940s, and since the late 1960s as a separate linguistic discipline. This progress became possible primarily thanks to the works by V. V. Vinogradov. A special role in the study of derivational processes in the Mordovian languages belongs to D. V. Tsygankin. The scholar described word formation as a system, defined basic concepts, characterized the methods of word formation, identified productive models, traced changes in word-building morphonology, developed the principles of studying word formation in higher education. Conclusion. A fairly large amount of material has been accumulated on the organization of the word-building system in the Mordovian languages. The number of works in the field of word building continues to grow, but not all of its problems have been resolved. For example, there is a need to develop a new classification of word building methods based on emerging data about the language.
