Innovative semantics of modern English prefixal verbs

The article is devoted to the study of neоlogisms of prefixal verbs of modern English. The essence of the concept of "neologism" and its definition based on the authoritative views of linguists and the author's vision are highlighted. The analysis of active conductive neological processes of the prefix verb in the system of modern English is carried out. It is noted that prefixation is the most productive way of forming verbs. It is proved that the main function of neologism is not only in naming a new subject of reality, but also in the need to clarify and form its semantics, is the result of linguistic and creative activities associated with the transition of a new verb unit from individual concrete usage to the language community. The argument is given that the evolution of innovative semantics in verbs occurs according to common law, i.e. lexical innovations can be associated with a new referent. The article outlines the perspective that rethinking and semantic shifts cause the processes of expansion and contraction of the semantic volume of the prefixal neologism, the formation of new meanings and changes in the scope of their functioning in modern English. The article concludes that the presence of a generalized invariant feature of the prefix in terms of language and its differential features in terms of speech, is a factor in generalizing different senses of the prefix verb. The description of the ways of verb neologisms and development of new meanings and uses of prefix verbs will have perspectives for lexicographic practice of compiling dictionaries of different types, will promote in-depth understanding, structural-semantic functional-pragmatic and word-forming aspects of verb neological vocabulary.
