Abstract
<jats:p>The article is devoted to the peculiarities of the formation of phraseological neologisms and the stability of socio-political terminology (SPT) term combinations, as well as the ways and mechanisms of phraseologisation, structural and semantic parameters of the new phraseology, a significant number of its semantic neologisms have arisen as a result of metaphorisation, due to the expansion of the semantic potential of the term itself. We believe that neological and metaphorical term formation expresses non-standard meanings that differ from the traditional ones. We interpret a neologism as a word that, in terms of the unity of form and content, compared to the term units recorded in lexicographical sources and Internet resources, is new and is part of the vocabulary of the professional language, i.e. a lexical unit that has been perceived as new for some time by the majority of specialists in a particular field of science. The formation of SPT neologisms is primarily due to the cognitive factor, i.e. the pronounced cognitive activity of a specialist aimed at adequate perception of special information. It is the terminological corpus that is the component of the professional language that is subject to constant changes due to the new cognitive and communicative needs of specialists. Thus, numerous new words-neologisms-appear as urgent correspondences to new communicative acts. The analysed material has shown that neologisms of the SPT are one of the main sources of enrichment of the lexical fund of the modern socio-political sphere. The reinterpretation of the semantics of existing lexemes in the language is carried out according to general linguistic laws, which determine the emergence of new meanings, the sphere of functioning, and the narrowing or expansion of the semantics of SPT. The work concludes that socio-political terms saturate texts with neological and emotionally expressive means, where pragmatic intention plays a key role. Usually, a socio-political term is characterised by logic and structure, semantic richness with established phraseologisms, idioms, abbreviations, etc. Thus, it is concluded that numerous new neologisms appear as term equivalents to new communicative acts in the socio-political sphere.</jats:p>
