Mood is a pervasive phenomenon across languages, but a challenging topic in formal semantics and pragmatics. This book is a highly valuable guide to the major approaches in the area and their considerable recent achievements. In Paul Portner, the field is fortunate to have a leading practitioner who is also a masterful explainer. With characteristic deftness and lucidity, he finds the sweet spot between rigor and accessibility, breadth of coverage and tautness of style. Mood is hands-down the best introduction and critical survey on the topic, and will be for years to come. Stefan Kaufmann, University of Connecticut sakriti opis
