The role of contrast is a growing area of interest in linguistics and
this book is an important contribution to the debate on where contrast
fits in the grammar. It argues that contrast is one of the central
organizing principles of the grammar and provides a formal theory of
contrast couched in the framework of optimality theory.
The book's key finding is that contrast exists as an independent
principle in the grammar, which in the framework of optimality theory
can be formulated as a family of rankable and violable constraints. A
formal proposal of contrast is developed called Contrast Preservation
Theory. This proposal is illustrated and supported with diverse contrast
phenomena in the areas of phonology and at the phonologymorphology
interface. Evidence is drawn from a number of languages including
Finnish, Arabic, and Polish. Predictions of the proposal are discussed
and compared with alternatives.
