This paper analyzes the syntactic properties of adverbial clauses in the Tsezic languages, a group of five to six languages from the Nakh-Daghestanian language family (Caucasus, Russia). These languages make heavily use of converbs and other non-finite verb forms in order to form complex sentences. The syntactic analysis presented builds on Bickel’s (2010) variables for the investigation of clause-linkage patterns and is based on data from natural texts. I mainly focus on coreference, scope properties, word order and extraction. Despite being closely related and syntactically rather similar, the Tsezic languages show some variation with respect to coreference and zeros in converbal clauses. This paper thus confirms the validity of microtypological studies and positions Tsezic converb constructions within a cross-linguistic typology of complex sentences.
