Przekształcenia w obrębie systemu imiesłowów czynnych w języku starobiałoruskim na przykładzie wybranych latopisów białorusko-litewskich

This article focuses on 16th-century written monuments of the Grand Duchy of Lithuania, representing the first and second Belarusian-Lithuanian redactions. Their common part – the Chronicle of Grand Dukes of Lithuania – was created in the Grand Duchy of Lithuania. The article analyses the changes occurring in the system of Old Belarusian active participles and compares them with all-Ruthenian state. The analysis has shown that in the participle system, on the one hand, some forms, such as inflectional forms of complex declension of active participles, tended to decline. On the other hand, a new morphological category was emerging, namely, undeclinable adverbial present and past participle.
