Functional Discourse Grammar (FDG) is a typologically-based theory of language structure. The major presentations of the theory are Functional Discourse Grammar (Oxford University Press, 2008), by Kees Hengeveld and J. Lachlan Mackenzie and A Functional Discourse Grammar for English (Oxford University Press 2015), by Evelien Keizer. FDG is understood as the grammatical component of an overall functional theory of verbal interaction.

A quick introduction to FDG

FDG arose in the first decade of this century in response to intensive discussion of its predecessor theory, Functional Grammar (FG). What these theories share is the belief that most formal properties of languages can best be understood if they are brought into correspondence with semantic and pragmatic categories that are rooted in human thought and in communication.

In the debate between formal and functional theories in linguistics, FDG adopts a middle position, believing that the forms and structures of languages should be properly described but also that these should be linked through the theory to the uses to which these forms are put.

An important principle of FDG is that it should be ‘typologically adequate’, by which is meant that it is equally applicable to languages of all types. FDG is accordingly much used in typological and language-comparative work, although it can also be applied in the description of individual languages.
