The data, observed in the writings by M. Mažvydas and other old Lithuanian texts, let us to distinguish some derivative isoglosses in the Old Lithuanian dialects of the 16th–17th centuries: 1. archaic nomina agentis with the suffix -tojas from primary verbs (cf. apgintojas ‘protector’) were widely used in Low Lithuanian and in the High Lituanian dialect of East Prussia; 2. the suffix -inykas (-ė), instead of -ininkas (-ė), was still used in Low Lithuanian; 3. the suffix -ybė played the main role in the formation of nomina qualitatis in the Low and High East Lituanian dialects;. nomina qualitatis with the suffix -imas / -ymas still preserved an abstract meaning in the texts by M. Mažvydas (cf. sveikimas ‘healthiness’ 713 ); 5. nomina actionis on -aujimas was characteristic feature of Low Lithuanian and the West High Lithuanian dialect of East Prussia (cf. paliaujimas ‘cessation’).
