Being typologically different, Russian and Bulgarian due to analytism and synthetism demonstrate differences in the functions of preposition used with noun forms and in case forms as well. If Russian prepositions reveal multiple meanings of a case form, whereas the basic meaning is carried by inflexion, in Bulgarian prepositions are indeed playing the major role in expressing case form meaning.
