Abstract
Based on a video recording of conversational British English, this paper tests within the framework of Multimodal Discourse Analysis whether two different subordinate structures are evenly integrated to their environment. Subordinate constructions have been described in linguistics as dependent forms elaborating on primary elements of discourse. Although their verbal characteristics have been deeply analysed, few studies have focused on the articulation of the different communicative modalities in their production or provided a qualified picture of their integration. The main hypothesis is based on the capacity of subordinate constructions to show distinct forms of autonomy depending on their syntactic type, thus expressing different degrees of break. Beyond showing that subordinate constructions are not evenly dependent on their environment depending on how speakers use the prosodic and kinetic modalities to express greater (in)dependency, the results suggest that the creation of a break mainly relies on prosodic cues. Changes in the modal configuration throughout the sequence suggest modalities are dynamic and flexible resources for integrating or demarcating subordinate constructions in function of their syntactic type.
