The aim of this paper is to consider the forms of the paremiological polysemy in the Electronic Russian-Belorussian-Ukrainian dictionary of proverbs which is now created within the framework of the project "Electronic dictionary of current active East Slavonic proverbs", funded by the Russian Foundation for Basic Research. Following the Russian paremiologist G. L. Permyakov, the paremiological polysemy is determined here as a special semantic feature of the paremiological system of one language along with the paremiological synonymy and antonymy. Paremiological polysemy is considered as an embodiment of the paremiological thematic multiplicity. Using the system-structural paremiographic approach, the author reveals the specifics of the definitions of the Russian current polysemantic proverbs and their active Belorussian and Ukrainian proverbial parallels.
