Translation of "Marrism" into Polish

The body of Marxist linguistic theories put forward by Marr and his followers (esp. I. I. Meshchaninov), in which language was regarded as monogenetic (with all languages developing from four elements, sal, roš, jon, and ber) and as belonging to social class rather than nationality (being, in Marxist terms, part of the social and economic superstructure rather than the base); advocacy of such theories.
