The paper examines the features of the linguistic discourse in French-language texts of modern scientific papers. The study proves that within the framework of studying linguistic texts, it is necessary to distinguish between the concepts of object-language, scientific theory, metalanguage, scientific discourse and metadiscourse. The analysis of 50 scientific articles based on the results of the World Congress in French Linguistics 2020, revealed metalinguistic, discursive and metadiscursive units that correspond to the levels and components of linguistic theory.
