The paper focuses on the interpretation of the basic linguophilosophical views of S.N. Bulgakov set out in his work Philosophy of the Name (1920, 1953). Philosopher and theologian S.N. Bulgakov expresses opinions on the essence of a word from the point of view of cogitology. The author interprets S.N. Bulgakov's explanations of such integrative terms as "word-thought", "logos" and "sound word". S.N. Bulgakov declares that a word is equated to an enlightened logos as a unity of words and thoughts, words and deeds, words and things. According to the philosopher, the meaning of a word is an idea embodied in the sound form of a word. In speech, the word-meaning turns into a word-thought. A thought comes true due to a speech-word. Language as a means of expression exists in its complete form long before the act of its designation. A thing is revealed in its name. The article also reveals the views of S.N. Bulgakov on words from the root, verbs-linker and pronouns that do not have their own content. The author believes that the results of the analysis in the article can enrich our ideas about language as an instrument of naming, designation and expression (cognitive aspect), and as a means of speech activity (communicative aspect).
