The dictionary of radical morphemes in A.S. Puškin's "Evgenij Onegin" is configured as a possible tool for the analysis of a literary text. The radical morpheme is observed not only from the semantic viewpoint (families of lexemes derived from a single radical morpheme), but also in formal terms. The identification of full and partial anagrams and of palindromes produced and derived from a minimum formal element (the radical morpheme and its allomorph variations) allows a search to be made for new, though minimum, "iterable" units (the base category of any literary text).
