"This book is the culmination of many years of research on Japanese consonantal morphophonemics, by two scholars already famous for their work in this area. The data are covered with unusual thoroughness and scholarly care, and the analyses have important implications for current issues in phonological theory: constraint conjunction, the nature of faithfulness constraints, and the form of the morphology-phonology interface."--Bruce Hayes, University of California Los Angeles "Ito and Mester provide a penetrating analysis of Japanese compound voicing ( rendaku) and explore its implications for Optimality Theory. Comprehensive in scope and elegant in presentation, it makes for a very impressive study." Michael Kenstowicz, Professor Of Linguistics, MIT "The empirical and theoretical depth of Ito and Mester's highly readable Japanese Morphophonemics are beautifully balanced, leading the reader to a rich, complete understanding of very complex material. Furthermore, the work presents the broader context of both theory and data throughout, making this a valuable reference book or teaching tool."
