The article is devoted to the emergence of neologisms in the Russian language through semantic derivation. The paper presents the case study of the verb orat’ (to yell), which illustrates the appearance of slang lexical-semantic variants of the word. The verb denoting screaming, crying and swearing in Russian literary language now functions in new meanings: ‘laugh’ and ‘experience indignation’. Constructions with this predicate mark the psychological state of a person (fun, joy, admiration, surprise or indignation), which has features of laughter Ya oru (I yell). The prominent specialty of this case is that the combinability of the verb does not correspond to the literary language norm. It has been established that in phrases formed according to a new control model, the new verb orat’ modifies nouns in the genitive case with the prepositions “s” “of” and “from”, while the genitive has the meaning of reason. A dependent word can be a designation of a person Ya oru s tebya / s druga / s Lekhi (I yell of you / of a friend / of Lyokha). It is noted that the slang verb orat’ began to be widely used around 2016, primarily in written formats of Internet communication, mainly among young people, although it can also be used in oral communication. The study reveals that the verb orat’ is mostly used in 1st person, singular (oru), however, the verb implements a complete inflectional paradigm in speech. The article gives assessment of derivational potential of the jargonism orat’ in the span of 5–6 years of functioning, the slang verb orat' acquired derivatives and became part of fixed expressions: proorat', ornut', orevo, orat' v golosinu.
