Abstract: The chapter presents the Interpersonal Level of FDG, which is modelled as a layered structure indicating the part-whole relations among units of discourse. The chapter shows how Discourse Acts group into Moves and are themselves built up from component elements, including the Communicated Content, which contains Subacts of Reference and Ascription.
