[email protected]. 1 What is Optimality Theory?1 John J. McCarthy University of Massachusetts Amherst Abstract. Optimality Theory is a general model of how grammars are structured. This article surveys the motivations for OT, its core principles, and the basics of analysis. It also addresses some frequently asked questions about this theory and offers suggestions for further reading. 1. Introduction In 1991, Alan Prince and Paul Smolensky began presenting their work on a new approach to language. By 1993, this new approach had a name — Optimality Theory — and it became known through their widely-circulated manuscript Optimality Theory: Constraint Interaction in Generative Grammar (hereafter, Prince and Smolensky (2004)). The impact of this work on the field of phonology was extensive and immediate; since 1993, it has also stimulated important research in syntax, semantics, sociolinguistics, historical linguistics, and other areas.
