Book excerpt: Metaphor and Metonymy at the Crossroads is a collection of essays, most of them written from a cognitive linguistics standpoint by leading specialists in the fields of conceptual metaphor and metonymy, and conceptual integration (blending). The book has two main goals. One of them is to discuss in new, provocative ways the nature of these conceptual mappings in English and their interaction. The other goal is to explore by means of several detailed case studies the central role of these mappings in English. The studies are, thus, concerned with the operation of metaphor and metonymy in discourse, including literary discourse or with the effect of metaphorical and/or metonymic mappings on some aspects of linguistic structure, be it polysemy or grammar. The book is of interest to students and researchers in English and linguistics, English literature, cognitive psychology and cognitive science.
