The article presents a corpus-oriented analysis of the terminological dominants of linguistic theory based on publications of the Odesa Linguistic School, which makes it possible to interpret its scholarly discourse as an institutionally coherent and quantitatively verified body of knowledge. The study is grounded in a combination of corpus-linguistic methods and linguistic data analysis, within which scholarly texts are treated as a structured informational resource. The corpus analysis encompasses the frequency-based parametrization of terms, the identification of their keyness, concordance analysis of usage contexts, modelling of collocational relations, and a diachronic assessment of the dynamics of the terminological system. The totality of these procedures provides a formalized description of the School’s metalanguage and its internal structural organization. The results demonstrate the presence of a stable invariant core of the terminological system, formed by basic and derivative terms of linguistic theory, as well as a dynamic periphery associated with the development of specialized subfields. Of particular analytical value is the subcorpus of suggestive linguistics, which emerges as an autonomous, statistically verified, and methodologically mature segment of the institutional discourse. The applied approach ensures the institutional validation of the Odesa Linguuistic School as an integral scholarly formation with its own metalanguage and a controlled innovative dynamics, and demonstrates the effectiveness of corpus-based and quantitative methods for the analysis of collective scholarly discourses in contemporary humanities research.
