The relevance of the selected topic is substantiated by its inclusion in the study of linguistics of the text, and namely linguistic units that fulfill connecting function in the text. The goal lies in determination of peculiarities of the conjunction “not only” and its correlates. The article employs introspective-inductive and descriptive methods. The research presses need to continue studying the text, methods of achieving its cohesion, and expressive means in the context. The conclusion is made that the conjunction “not only” can be qualified as binary graded conjunction with certain peculiarities. Its uniqueness lies in specific manifestation of the gradation meaning; textual character (reference to pretext); instability of its composition; absence of correlate characteristic to this conjunction. Thus, “not only” performs the function of a conjunction and a text bond. The novelty of this research consists in describing the functionality of conjunction “not only” with its various correlates.
