The article focuses on short-rooted infixal and sta stem verbs ending with sonants l, r, m, n, v, j which were attested in old Lithuanian scripts dating back to the 16–17st century and representing different written variants. The aforementioned verbs typically have a wide spectrum of constructional alternations. The morphological structure of verbs attested in the old scripts alternates similarly to those forms found in Lithuanian dialects, however, there are some notable differences as well, that is why the verbs found in old scripts are compared to those found in Lithuanian dialects and contemporary Lithuanian in order to determine the localization of alternating forms, their chronological and areal distribution as well as the tendencies and motives for their structural change.
