The article is devoted to revealing the phenomenon of contemporary changes in the language space, in accordance with the processes of transition that take place in the economy of Ukraine in the context of knowledge representation, neuro-modeling and artificial intelligence. The relevance and expediency of the study are due to the uncertainty to some extent of innovative processes occurring in the development of the contemporary Ukrainian language in connection with the transitional processes in the economy. The relevance of the study is determined by: 1) the importance for contemporary linguistics of identifying and describing the structural and typological features of the “dominant” (according to Zagorovskaya) lexical and semantic subsystems of the contemporary Ukrainian language, reflecting the most significant concepts of contemporary Ukrainian conceptosphere; 2) the importance of the lexical subsystem of public administration not only for the contemporary Ukrainian language and contemporary Ukrainian national consciousness, but also for the effective economic policy of the state; 3) a lack of special generalizing research on the problems of formation, development and current state of the Ukrainian vocabulary of state regulation of the economy; 4) the need to clarify and improve the methodology of complex analysis of lexical and semantic systems in the Ukrainian language, methods and techniques of describing lexical units in synchronous and diachronic aspects. 5) current needs in the use of artificial intelligence, based on the principles of neuro-modeling in the representation of knowledge in the conditions of transition economy of Ukraine.

The article shows that lexico-semantic innovations in the Ukrainian language system of proper names which are characterized by a specific neurophysiological mechanism of formation require in-depth study. The relevance of the article lies in the fact that lexico-semantic word formation used to be mainly considered in the diachronic aspect, which led to little attention to ergonyms and pragmonyms as relevant classes of proper names. The article aims to analyze lexico-semantic innovations in the context of ergonyms and pragmonyms and determine their role in word formation in the system of naming-related tools in the modern Ukrainian language. Research methods include observations, analogies, analysis, synthesis, linguistic description, component analysis, structural-semantic analysis, statistical methods. The article proves that lexico-semantic word formation is the most active and productive way of replenishing the fund of ergonyms and pragmonyms in the Ukrainian language under the conditions of a transition economy. The main types of lexico-semantic word formation are derivational metaphor and derivational metonymy. They enable the formation of both simple and compound lexico-semantic innovations mostly represented by binary word combinations. Including all layers of vocabulary in the scope of such a type of word formation can bring unlimited prospects of its functioning in the future. The international value of the research implies clarifying the role of lexico-semantic word formation in the naming system of modern Ukrainian, describing important fragments of the lexical structure of the Ukrainian language, systematizing modern lexico-semantic naming models, and determining the ways of activating lexico-semantic substitution. For the first time in Ukrainian linguistics, the research analyzes peripheral classes of proper names in various ways, classifies ergonyms by thematic groups and motivational features underlying the naming unit and reveals the specifics of different semantic groups of Ukrainian pragmonyms.

The article analyzes traditional views of Ukrainian linguists on the consideration/disregard of neurocognitive factors in the lexical-semantic way of word formation (hereinafter “LSWWF”). The relevance of the article lies in a pronounced divergence in the views, as well as in the contradictions in the interpretation of polysemy as a result of this type of word formation. Research methods include analysis of definitions and basic theories, comparison, extrapolation of a neuroscientific perspective on the cognitive nature of metaphorical generation of new meanings on traditional (structural and functional) approaches to linguistic phenomena. The article proves that Ukrainian linguistics involves prerequisites and basics of cognitive subject-based explanation of secondary semantics, present since the Soviet period, and lacks categorical and methodological tools for its interpretation. Besides, the authors of the article suggest some compromise solutions to these contradictions without completely abandoning traditional views on word formation. The international relevance of the article is seen in its attempts to reconsider the significant traditional achievements of Eastern European linguistics (on the example of Ukraine) in the context of objective natural neurocognitive views on key linguistic processes, in particular LSWWF.

The article deals with the multifaceted mechanisms of onym formation in the Ukrainian language today and analyzes them in the context of studying linguistic courses and acquiring practical skills in their use. It proves that motivational connections in the language system are found to be typical, regular, regular, which allows us to distinguish several model varieties of lexical and semantic word formation (hereinafter “LSWF”). Only the transfer of the name, in our opinion, should be discussed in the creation of motivated models of onyms. It is simply impossible to talk about any figurative meaning. If we can talk about any transfer, then only about the transfer of a lexical unit from one denotation to another in the presence of speakers permanent (temporary) ideas, ideas about external, functional, spatial or other similarities and proximity of objects - ideas that reflect the real, desired or completely fantasy state of the sphere of the material and spiritual world to which this object belongs. These mechanisms can be analyzed from both linguistic and psycholinguistic (neurolinguistic) points of view. They also objectify universal ways of comprehending and representing a rapidly changing world verbally. Furthemore, the article confirms that the main and most productive models of LSWF at the present stage are derivational metaphor (hereinafter DMF) and derivational metonymy (hereinafter DMT). We consider it possible to use these terms because with the help of DMF and DMT new words are created, not new meanings of words. The use of phrases as a function of proper names (PN) is one of the traditional ways of nomination. Their activation is due to two intralinguistic factors: the tendency to expressiveness and the tendency to maximum motivation of language units.
