The article is devoted to the study of the implementation of important properties of interdisciplinarity and interparadigmality in the methodology of linguography of the language system of a separate idiom. The methodological basis of the researched lingual as an integrative paradigm of the idiom is determined, and the description is qualified by the manifestation of interdisciplinary and multifunctionality in the multifaceted scientific analysis of the idiom discourse. Positioning the theoretical justification, methodological and technological expression of the analysis, it is proved that the linguography of the idiom system is a combination of scientific interdisciplinarity and linguistic interparadigmality The purpose of our research is an attempt to determine interdisciplinarity and interparadigmality in the methodology of linguography of the idiom system. The methodology of lingual description as a fragment of idiomological research has a linguistic system approach, different from dialectological studies, with the definition of the main methods of theoretical and experimental linguography, conceptual technologies of linguography, etc. The object of research is linguarium, that is, the language system of a separate speech (idiom). The subject of the study is the methodology of the linguistic description of speech in the plan of realizing interdisciplinarity and polyfunctionality in the verbalization of realities-representatives of the idiom discourse. The actual material of the research is the results of the methodological analysis of the lingual as a language system, in which the linguistic context is modeled on the basis of the ideas of polyparadigmality, polyapplicability, which is the integration of communicative, social, semantic, subjective, motivational, production and other contexts. The methodological concept of idiomological research is the language-systemic approach – the linguographic one, which is defined by us, based on the priority ideas of the new field of scientific knowledge, and in the lens of linguistic interpretation is the idiom as a phenomenon, in particular, its theoretical sphere. The object of linguistic methodology as an idiom description is the lingual of the idiom, and therefore the implementation of the research task reflects the macro process of the formation of a new linguistic paradigm. The methodology of description of monoidiomic lingual offers a wide interdisciplinary approach to the linguistic means of embodying the phenomenon of lingual and a multifaceted characterization of the elements of the idiom system. Methodologically justified linguistic completeness of an idiom represents a high level of proof of linguistic research. We see the perspective of the linguistic description of the idiom system in the integration of research methods, techniques, processes and procedures in an interdisciplinary plane.
