The de Gruyter lexicon Metaphor Theories provides a comprehensive introduction to the concept of metaphor, a compendium-like overview of all metaphor theories, and an extensive bibliography on the topic. Existing metaphor theories are divided into four main categories: 1. structural theories (Coseriu, Jakobson, et al.), 2. pragmatic theories (Searle, Grice, et al.), 3. semantic theories (Ricoeur, Danto, et al.) and 4. functional theories (Bühler, Blumenberg, et al.). The lexicon is a reference work on the phenomenon of metaphorical speech - an intensely discussed topic in the fields of literary science and linguistics, as well as in philosophy.
