Blurb:

This chapter is concerned with the development of accounts of lexicogrammar in Systemic Functional Linguistics (SFL) since the 1970s – in particular, with
accounts relating to Halliday’s Introduction to Functional Grammar (IFG), the first edition of which was published in (1985). IFG has infl uenced other
accounts both within SFL (see e.g. the contributions by Fawcett, Chapter 28 and by Tucker, Chapter 29) and outside SFL (see e.g. Kay, 1979; Lockwood, 2002), in other traditions; but my focus is on the IFG tradition itself. The boundaries are, of course, quite indeterminate – the tradition is not a bounded body of dogma, but an open-ended network of ideas about lexicogrammar.
