The article describes the system of phraseological units used by the narrator of O. Slonovska’s novel «Instinct of the Locust» (Kyiv: Ukrainian Priority Publishing House, 2019), who is a journalist. A set of these phraseological means is called a phraseological portrait. We understand it as a stable combinations of words inherent to a certain person, which are used in the personal speech to communicate, analyse the behaviour of interlocutors or characterize their character traits. In the analysed novel, the narrator uses phrasemes, which primarily perform a textual, stylistic, and plot-creating function. Book idioms play a leading role in the system of language means of the journalist’s artistic understanding of reality. They define this style as a person of high intelligence, an elite linguistic personality, capable of creating texts that are perfect in terms of content and form. The narrator achieves the localisation of the presentation, evidentiality, argumentativeness of the statement thanks to the skilful combination of book and colloquial phrases in the same context. The expressiveness of the statement is enhanced in connection with the use of imagery and emotionality natural for phraseological units, the creation of contextual conditions for synonymy, antonymy, oxymoron, synecdoche, as well as the use of stable combinations of words with figurative concretizers that have archaic symbolism. The most phraseologically loaded nouns in the text are the nouns leg, eye, hand, world, word, tongue, which perform the function of figurative concretizers of several phrasemes. Often, stable combinations of words in the narrator’s speech can play the role of standards, stereotypes of the cultural and national worldview or indicate their symbolic nature.
