Written by a team of leading experts, this groundbreaking handbook provides the first comprehensive and current account of Natural Linguistics. It offers a state-of-the-art survey of the theoretical developments that have arisen from, or are related to, the framework of Natural Phonology – across subfields as diverse as phonology, morphology, morphophonology, syntax, pragmatics and text linguistics. The handbook is split into five parts, with chapters covering the origins, foundational principles, semiotic, cognitive and functional bases of Natural Linguistics, as well as external evidence for the theory, and a critical appraisal of its position amongst modern linguistic theories. It fills a gap in the available accounts of modern linguistic theories and demonstrates the potential of the theory to a wider audience, addressing both advocates of the school, and those who are open to alternative approaches to linguistic science. It will be a definitive reference work on Natural Linguistics for years to come.
