This book brings together research on the topic of causation from experts in the fields of linguistics, philosophy, and psychology. It seeks to arrive at a more sophisticated understanding both of how causal concepts are expressed in causal meanings, and how those meanings in turn are organized into structures. Chapters address some of the most exciting current issues in the field, including the relata of causal relations; the representation of defeasible causation within verb phrases and at the level of modality; the difference between direct and indirect causal chains; and the representation of these chains in syntax. The book examines data from a wide variety of languages, such as Tohono O'odham, Finnish, Tagalog, Vietnamese, Hindi, and Karachay-Balkar, and will be of interest to syntacticians and semanticists, as well as psycholinguists and philosophers, from graduate level upwards.
