ИСТИНА

The Old Novgorod Russian (ONR) system of clitic placement could not be derived from the Old South Russian (OSR) / Old Church Slavonic (OCL) system, but the latter could be derived from a ONR-like system. •Modern Slavic systems with 2P clitics originate from a ONR-like system. •Andrej A. Zalizniak‘s ( 2008) claim that weak clitics‘ (dat., acc. pronouns, BE-auxiliaries) behaved as non-clitic words in OSR/OCL is not tenable. •In the OSR/OCR pronouns and auxiliaries behaved as verbal clitics. This fact implies that after the disintegration of Proto-Slavonic clitics belonging to the latest cliticization layer, did not have 2P-properties any longer. •The BE-auxiliries could still cliticize and develop in the direction of 2P clitics in a group of conservative Slavic dialects (ONR, Slovene, Carpatian Ukrainian).
