Category of person in language system and in speech system

Problem Statement. The article presents a short description of the problem that can be seen in the sphere of semantics of the category of person as a peculiar kind of category considered in the paradigmatic and syntagmatic aspects. The description is given from the viewpoint of the theory of psycho-systematics. The Purpose of the article is to describe, on the basis of our own research experience, the conceptualsemantic mechanism of formation and functioning of the category of person on the level of word, sentence and text, considering upon that the units of the language mentioned above as very significant entities. Results. The conceptual approach to the analysis of deep content of the category of person allows to determine hypothetically isomorphism of the process of language units structuring in the system of language and the system of speech. The content characteristic of the logic person becomes established in accordance with its role as a support on the conceptual level in the form of a visual notion about the object of speech. On the level of sentence it turns out to be the subject representing the performer of the action, and on the level of text it is a person of the personage. Conclusions. The effects of the meanings of the category of person both on the level of language system and on the level of speech system allow to come to the conclusion that this category provides isomorphism of linguistic levels being a support of the conceptual content of language units. The object of speech is a logic person, the support is constantly present either in the concealed aspect or in the open one in all grammatical forms of the verbal person. The presence of the logic person in the noun, in the form of the third person «he» seme, determines its «part of speech» linguistic essence as of a word with inner incidence content. The logic person is also the initial conceptual category for linguistic units of other levels.
