The authors define phraseological unit as a linguistic concept, indicate the parameters of phraseological units, their types, and research methods (method of continuous sampling, definitional analysis), describe the influence of language on the style of discourse. This paper discusses the use of phraseological units in a political blog (based on the material of the American blog) to describe the problem (in this case, the opioid crisis) and counter it. The work deals with the question of both figurativeness and ability of phraseological units to incapsulate a large amount of information. The language of blogs is interesting in that it is a fusion of spoken language and written language, respectively, there one can find both clericalism, cliches, and phrasal verbs (which are ranked by some scholars among a number of phraseological units). The paper aims at considering the phraseology of the American blog, namely, its use in describing a specific social problem.
An analysis of the examples has shown that the use of phraseological units in political discourse is usually conditioned by stylistic and rhetorical goals, and the emergence of new terms often occurs due to the modification of phraseological units at the semantic level. The results of the work can be applied in studying lexicology, phraseology and stylistics.
