“…Though it is important to stress that the acquisition of accusative is found in all CB branches, as one finds accusative case marking in East Slavic (Old and Modern Ukrainian and Belarusian [Lopatina, 2000:139], sporadically in North Russian varieties [Matveenko, 1960:352]), West Slavic (Polish), Baltic (Lithuanian East High varieties), and there is also accusative case marking of the core argument with personal pronouns in Fennic languages. The accusative object marking is first attested in the Russian texts from the 16th to 17th century (Borkovskij and Kuznecov, 1963:398-399;Filin, 1972;Jung, 2007:149;Lopatina, 2000:139;Sprinčak, 1960: Several scholars believe that the accusative case-marking constitutes a morphological copying from Polish into Ukrainian, Belarusian (inter alia, Moser, 1998:340, Shevelov, 1969 in press-a) and into some Eastern Lithuanian vernaculars (Danylenko, 2005b). However, a case assignment pattern can hardly be borrowed without the underlying syntactic structure.…”
