The development of word formation theory in the works of representatives of the Kazan linguistic school: history and modernity

The contribution of I.A. Baudouin de Courtenay and his followers A.I. Anastasiev, N.V. Krushevsky, V.A. Bogoroditsky to word formation theory has been described in sufficient detail, but the achievements of Kazan University representatives in the late 20th - early 21st centuries have not been fully studied yet. This substantiates the relevance of the present study. The aim of the study is to characterize the word formation theory development in Kazan University since the late 19th century. The material for the study was the scientific works by I.A. Baudouin de Courtenay and his followers (A.I. Anastasiev, N.V. Krushevsky, V.A. Bogoroditsky), as well as the works of Kazan University representatives in the second half of the 20th - early 21st centuries (V.M. Markov, G.A. Nikolaev, E.A. Balalykina, V.A. Kosova, etc.). The main methods used in the study were review, descriptive and induction method, analysis and comparison. Our review of the works by Kazan University scientists confirms and deepens earlier conclusions about word formation theory development at the university since the end of the XIX century until 2025. I.A. Baudouin de Courtenay and his followers referred word-formation to morphology, created the classical morpheme theory, investigated word structure and some Russian affixes, revealed the prerequisites for defining the concept of wordformation meaning and word-formation paradigm, and made many other important discoveries in the field of linguistics. Kazan University representatives of the second half of the XX - early XXI century relied to a great extent on the results of their predecessors. V.M. Markov and G.A. Nikolaev made a significant contribution to historical word formation in the Russian language; E.A. Balalykina, G.A. Nikolaev, and other linguists worked in the field of comparative word formation; G.A. Nikolaev, T.M. Nikolaeva, I.V. Erofeeva studied functional word formation; V.A. Kosova developed the structural-semantic aspect of word formation. The analysis of theoretical works shows the continuity in studying word formation at Kazan University.
