Set Phrase as a Syntactic Phenomenon

This article is devoted to the derivational features of phraseological expressions, and the author examines the derivation of phraseological expressions from the syntactic point of view. The article also considers the integrity of phraseological expressions and the continuity of syntactic relations that form a shell indivisible with the meaning of a single element. The syntactic derivation of phraseological expressions (like the derivation of phraseological expressions as stable combinations) does not differ much from the derivational properties. The difference between them is observed in expressions with the structure of the sentence.
