An accessible and thorough introduction to implicatures, a key topic in pragmatics. It will appeal to students and teachers in linguistics, applied linguistics, psychology and sociology, who are interested in how language is used for communication, and how children and second language learners develop pragmatic skills. '? will be indispensable for those focussing on implicatures in teaching or research. Most helpful is its consideration of implicatures from within the three different frameworks. I commend the authors for this useful contribution to the field of pragmatics.' Todd A. Scacewater, Journal of Language, Culture, and Religion
