Metaphor in grammatical works of linguists

The object of the research is metaphorical nominations in scientific linguistic discourse. The purpose of the study is to systematically describe the structural and semantic features of metaphors in grammatical works. The identification of expressive linguistic units in scientific texts is important for a comprehensive study of the relationship between rational and emotional in strict speech styles. The appeal to this topic is dictated by the need to find ways to present complex theoretical material in university syntax teaching. The article considers metaphors-words, metaphors-phrases and metaphors-predicative units characterizing transitional phenomena in the grammar of the Russian language. Metaphorical designations in the description of the desemanticized verbal components of analytical constructions and verbal connectives are highlighted. Metaphors characterizing other grammatical phenomena are analyzed. The role of verbal metaphors in the description of constitutive features of sentences of different types is established. The features of substantive and adjectival metaphors in grammatical works are noted. It is shown that the expanded metaphors demonstrate the multidimensional nature of syntactic categories. It is concluded that verbal and substantive metaphors convey the desire of linguists to present the grammatical system as dynamic, actively developing. The use of metaphorical names makes it possible to present grammatical theory in a more accessible way, to draw attention to interesting linguistic facts.
