Phraseological occasionalisms: their text functions and ways of formation

The article deals with the problem of the author’s individual transformation of phraseological units, which is regarded as an occasional phraseological derivation. Occasional phraseological units are determined by the communicative and pragmatic goals pursued by the author of the text. A conducted linguistic analysis suggests that a derivative unit retains derivational connections with the motivational phraseological unit. Transformative possibilities of phraseological units depend on the structure, semantics, figurative meaning of produced phraseologies, and their ability/inability to grammatical changes. According to the results of the research, unique phraseological occasionalisms are assistive in the creation of the effect of novelty and freshness of the problem perception. It also emphasizes emotiveness and expression. The most striking phraseological occasionalisms, due to their popularity, are used in the language of other authors, and, as a result, gradually become part of the lexical-phraseological system of the Russian language.
