Optimality Theory revolutionized the field of phonology and had a huge impact on linguistics in general when it was first proposed in 1993. In Doing Optimality Theory, one of the key proponents of the theory explains how to do analysis and research using this model. Because the basic premises of OT are markedly different from other linguistic theories, new analytic techniques and new ways of thinking and theorizing are required. This unique work presents practical, in-depth advice for students in the field in an engaging and accessible way. Numerous questions, specific examples, and exercises throughout are designed to give readers an in-depth understanding of the material.
