PHRASEOLOGIZED SENTENCES: MODELS AND THEIR VARIABILITY
The article examines a type of syntactical phraseological units - sentences of the phraseologized structure (FS). The author analyzes FS variability as one of their typical features, which distinguishes them from lexical phraseological units (the variability of the latter is rare enough). FS variability is conditioned by their dual grammatical nature. Some FS variants represent their phraseological nature, others are conditioned by their typical syntactical features. FS variability is implemented strictly within the framework of their stability.
