The de Gruyter Lexicon Metaphertheorien offers a comprehensive introduction to the concept of metaphor, an overview of all metaphor theories, and a detailed bibliography on the subject. The existing metaphor theories are divided into four main categories: 1. structural theories (Coseriu, Jakobson and others), 2. pragmatic theories (Searle, Grice and others), 3. semantic theories (Ricoeur, Danto and others), and 4. functional theories (Bühler, Blumenberg and others). The lexicon serves as a reference work on the phenomenon of metaphorical speech, which is extensively discussed in literature, linguistics, and philosophy. Key features include a basic introduction to the concept of metaphor, a comprehensive presentation and categorization of all existing metaphor theories, and a reference work on a central subject in the humanities. Indispensable for scholars.
