On the place and role of ‘discourse’ in the Functional Discourse Grammar model. The interface between language system and language use

Mackenzie (2020) is a defense of the position adopted by the architects of the standard model of Functional Discourse Grammar (FDG): namely that the model cannot (and even could never) be considered a ‘grammar of discourse’. The article examines the arguments given for rejecting the ‘discourse’ dimension from the FDG model, proposes an independent account of discourse, and suggests a means of dovetailing it within a model of the wider utterance context. On the one hand, the author's arguments are in the main valid: for ‘discourse’, as characterized in section 3, is not a formal, clearly delineated object amenable to systematic treatment within a grammatical model of a given language. Yet on the other, it is arguable that even the presence of the term ‘discourse’ in the model's name is not in fine justified. Notwithstanding, in order to include the ‘discourse dimension’ (section 3), it is argued that the Core FDG model could be integrated with a broader model of the utterance context involved. This would enable it to account more adequately, for example, for the ways in which indexical reference, the lexicon and adjectival modification operate in actual texts. In turn, it would influence certain of the other characterizations independently assigned within the Core model.
