~ ROA Version, 8/2002. Essentially identical to the Tech Report, with new pagination (but the same footnote and example numbering); correction of typos, oversights & outright errors; improved typography; and occasional small-scale clarificatory rewordings. Citation should include reference to this version.

Ch. I. Remark. The authors’ names are arranged in lexicographic order. Acknowledgments Special thanks to John McCarthy for detailed discussion of virtually every issue raised here and for a fine-grained skepsis of the entire first draft of the ms., which resulted in innumerable improvements and would have resulted in innumerably more, were this a better world. We are particularly grateful for his comments and suggestions in r‘ Chs. 7 and 9. We also wish to thank Robert Kirchner, Armin Mester, and Junko Itô for remarks that have had significant impact on the development of this work, as well as David Perlmutter, Vieri Samek-Lodovici, Cheryl Zoll, Henrietta Hung, Mark Hewitt, Jane Grimshaw, Ad Neeleman, Diana Archangeli, Henry Churchyard, Doug Pulleyblank, Moira Yip, Tom Bever, Larry Hyman, Andy Black, Mike Jordan, Lauri Karttunen, René Kager, Paul Kiparsky, Mike Kenstowicz, Ellis Visch, András Kornai, Akin Akinlabi, Géraldine Legendre, Clayton Lewis, Merrill Garrett, Jim Martin, Clara Levelt, Mike Mozer, Maria Bittner, Alison Prince, Dave Rumelhart, Mark Liberman, Jacques Mehler, Steve Pinker, Daniel Büring, Katharina Hartmann, Joshua Legendre Smolensky, Ray Jackendoff, Bruce Hayes, Geoff Pullum, Gyanam Mahajan, Harry van der Hulst, William Labov, Brian McHugh, Gene Buckley, Will Leben, Jaye Padgett and Loren Billings. None of these individuals can be sensibly charged with responsibility for any errors that may have crept into this work. To Merrill Garrett (Cognitive Science, University of Arizona, Tucson) and to the organizers of the Arizona Phonology Conference we are grateful for providing in April 1991 the first public forums for the presentation of the theory, which proved a significant stimulus to the cohering thereof. We would also like to thank audiences at our 1991 LSA Summer Institute course and at the Feature Workshop there, at WCCFL 1992, at the OTS (Utrecht), University of California at Berkeley (Phonology Laboratory), the University of Colorado at Boulder and the Boulder Connectionist Research Group, Rutgers University (New Brunswick and Piscataway), Brandeis University, the University of Pennsylvania (the Linguistics Department and the Institute for Research in Cognitive Science), Princeton University Cognitive Science Center, Stanford University (Phonology Workshop and Parallel Distributed Processing Seminar), the University of Rochester Cognitive Science Program, and the International Computer Science Institute of Berkeley CA. Financial support was provided by a University of Colorado Faculty Fellowship, by research funds from Rutgers University and from the Rutgers Center for Cognitive Science, and, most crucially, by NSF SGER BNS-90 16806 without which the rigors of long-distance collaboration would have proved daunting indeed. We remember Robert Jeffers with special appreciation for constructing the Rutgers environment that so greatly facilitated the progress of this work. Table of Contents 1.
