This book provides ten case studies in Functional Discourse Grammar (FDG), a typologically-oriented theory of the organization of natural languages that has risen to prominence in recent years. The authors, all committed practitioners of FDG, include Kees Hengeveld, the intellectual father of the theory, who shows how it offers a radically new approach to constituent ordering. Other themes covered are evidentiality, modality, adpositions, verb morphology, possession, raising, sequence of tenses, semi-fixed constructions and prelinguistic conceptualization. The volume contains an introduction that explains the rudiments of FDG and summarizes the ten remaining chapters. The Casebook moves on from Hengeveld & Mackenzie's (2008) Functional Discourse Grammar to show how the theory is applied to linguistic problems new and old. The languages treated are Blackfoot, Dutch, English, Spanish, Welsh, indigenous languages of Brazil, and many others.
