This state-of-the-art guide to some of the most exciting work in current linguistics explores how the core components of the language faculty interact. It examines how these interactions are reflected in linguistic and cognitive theory, considers what they reveal about the operations of language within the mind, and looks at their reflections in expression and communication. Leading international scholars present cutting-edge accounts of developments in the interfaces between phonetics, phonology, morphology, syntax, semantics, and pragmatics. They bring to bear a rich variety of methods and theoretical perspectives, focus on a broad array of issues and problems, and illustrate their arguments from a wide range of the world's languages.
