Chapter 4. The textual functions of lexis
This chapter reviews studies which show how lexis contributes to textual organisation. It concludes that there are many interesting case studies, but that some hypotheses could be formulated more explicitly, and that findings could be better integrated into a functional theory of lexis. As a short illustration of the detailed descriptive work which is still required, it provides a case study of the textual functions of one lemma (ALLEVIATE).
