Book: Hidden Generalizations
Chapter: Opacity, derivations, and Optimality Theory
This chapter begins by explaining what opacity is and how it is analyzed in rule-based phonology. The discussion then turns to a description of ‘classic’ Optimality Theory, the problems that opacity presents for classic Optimality Theory, and various ideas about how to modify the classic theory to accommodate it. The chapter ends with the conclusion that there is something fundamentally correct about rule-based phonology’s serial derivation.
