Formation and development of the concept of “Word-Forming Category” in the derivatology of the modern Ukrainian literary language

The relevance of the proposed study is determined by the need to trace the chronological stages of the formation of term names in order to define the concept of “word-forming category”, which will contribute to the terminological arrangement in Ukrainian derivatology. The aim of the study is to comprehensively study the content of the concept of the “word-forming category” in the modern Ukrainian language, in particular its evolution, structural organization, and interaction with other categorical units of the language system, with an emphasis on terminological ordering in Ukrainian derivation. To achieve the goal, a number of special linguistic methods were used, in particular, diachronic, definitional, and functional analysis, as the historical-linguistic, comparative-typological, and semantic-structural methods. It was determined that according to the principles of modern functional-categorical grammar, a word-form is located between syntax and morphology, forming its categories in the structure of a sentence or phrase and using morphological means for this purpose.
