jats:pThis paper discusses two case studies of microvariation in accusative marking in the Italo-Romance varieties of the extreme south of Italy. In particular, the diatopic variation displayed by the dialects of southern Calabria gives rise to peculiar patterns of alternation between presence or absence of the marker a ‘to’ in flagging the accusative. The realisation of accusative case is partially governed by semantic and referential features, i.e. specificity and animacy. In addition, the nature of the realisation of the D head results in a degree of competition between zero marking and analytic accusative marking with a. Given the century-long co-existence of Latin/Romance and Greek in southern Calabria, the relevant morphosyntactic patterns in Case-marking will also be examined from a language contact perspective. We will highlight how the relevant outcomes do not simply involve borrowing mechanisms or template copying from the lending variety but, rather, produce hybrid structures no longer ascribable to a purely Romance or Greek grammar.</jats:p>
