An authoritative general introduction to cognitive linguistics, this book provides up-to-date coverage of all areas of the field and sets in context recent developments within cognitive semantics (including primary metaphors, conceptual blending and Principled Polysemy), and cognitive approaches to grammar (including Radical Construction Grammar and Embodied Construction Grammar). While all topics are introduced in terms accessible to both undergraduate and postgraduate students, this work is sufficiently comprehensive and detailed to serve as a reference work for scholars from linguistics and neighbouring disciplines who wish to gain a better understanding of cognitive linguistics. The book is divided into three parts (The cognitive linguistics enterprise; Cognitive semantics; and Cognitive approaches to grammar), and is therefore suitable for a range of different course types, both in terms of length and level, as well as in terms of focus. In addition to defining the field, the text also includes appropriate critical evaluation. Complementary and potentially competing approaches are explored both within the cognitive approach and beyond it.In particular, cognitive linguistics is compared and contrasted with formal approaches including Generative Grammar, formal approaches to semantics, and Relevance Theory.
