The article is devoted to research into the systematization of the structural and semantic types of partially phraseologized sentences. Partially phraseologized sentences have been ascertained to have their functional and communicative purpose in language and speech. The formal and semantic principles of the typology of partially phraseologized sentences have been determined. Structural typologies of partially phraseologized sentences are based on quantitative and morphological criteria. Analyzed have been the structural types of partly phraseologized sentences. Partially phraseologized sentences are formed by two‑, three‑, four‑, and five‑part phrase‑complexes. The semantic types of partially phraseologized sentences are based on the type of syntactic relations between their two parts, depending on which we can single out: 1) sentences with temporal relations; 2) sentences with relations of generalized condition; 3) sentences with explanatory relations; 4) sentences with applicative relations.
