New in paperback. Hardcover was published in 2010. This is the first cross-linguistic study of imperatives, and commands of other kinds, across the world's languages. It makes a significant and original contribution to the understanding of their morphological, syntactic, semantic, and pragmatic characteristics. The author discusses the role imperatives and commands play in human cognition and how they are deployed in different cultures, and in doing so offers fresh insights on patterns of human interaction and communcation.
