Preface

The University of Pennsylvania Working Papers in Linguistics (PWPL) is an occasional series published by the Penn Linguistics Club, the graduate student organization of the Linguistics Department of the University of Pennsylvania. The series has included volumes of previously unpublished work, or work in progress, by linguists with an ongoing affiliation with the Department, as well as volumes of papers from the NWAV conference and the Penn Linguistics Colloquium. The current PWPL series editors are Lukasz Abramowicz, Sudha Arunachalam, Loren Delfs, Aaron Dinkin, Aviad Eilam, Keelan Evanini, Michael Friesner, Jonathan Gress-Wright, Kyle Gorman, Catherine Lai, Laia Mayol, Giang Nguyen, Maya Ravindranath, Tatjana Scheffler, and Joshua Tauberer. We thank the Graduate Students Association Council of the University of Pennsylvania for financial support. This volume contains the proceedings of the 30th Annual Penn Linguistics Colloquium, held from February 24-26, 2006, at the University of Pennsylvania in Philadelphia.
