Referring to the possibility and need for an experiment in literary studies, mentioned in the early XX century by the Soviet literary theoretician and poetry scholar Boris Yarkho, who paid particular attention to the transformation of the genre and the structure of expressive means as a whole, the author of this article analyzes the new form of the Russian verlibre (free verse), its varieties of the most probable form, attempting to determine its most characteristic typology, as well as to introduce into the concept of the matryoshka verlibre the two main forms, two of its fundamental metaphases and several subvarieties: 1. Verlibre in verlibres (verlibre in several verlibres); 2. Verlibre in verlibre (several verlibra in one verlibre). The author also distinguishes two subvarieties that are formed from the verlibre in verlibre: 3. Veprlibr (large verlibre in several verlibres); 4. Aphoristic verlibre (verlibre in several aphorisms), and others. The main conclusion of the conducted analysis of the new form of the matryoshka verlibre consists in the fact that matryoshka verlibre is patterned by a catenate fairy tale and is attributed to the type of catenate fairy tale (cumulative fairy tale, recursive fairy tale, chainlike fairy tale). The verlibre, in which dialogues or actions are repeated and develop in a modified form according to the plotline, belongs to the matryoshka verlibre. The effect of these verlibres is based on the repeating narrative, characteristic image and action changing for one or another reason and reaching culmination. In this case, semantic differentiation of the text is viewed as a synthesis of both dimensions, where any component of the work is simultaneously motivated by the coherence of such element that it creates with other elements, as well as semantic union of the elements that are subject to destruction, and belong to different components of the entire work. A matryoshka doll serves as an example.
