Subjecthood and the notion of instantiation

The cornerstone of this argument is Davidse's cognitive-functional definition of the Subject as Instantiator. By realigning Davidse's interpersonal characterization of the Instantiator with Halliday's triad of interpersonal, ideational and textual metafunctions of language, I argue that the Subject/Instantiator is the primary syntagm-forming element for realizing processual meanings.
