The University of Pennsylvania Working Papers in Linguistics (PWPL) is an occasional series published by the Penn Graduate Linguistics Society. The series has included volumes of previously unpublished work, or work in progress, by linguists with an ongoing affiliation with the Department, as well as volumes of papers from NWAV and the Penn Linguistics Colloquium/Conference. This volume contains selected papers from the 43rd Penn Linguistics Conference, held from March 22-24, 2019 in Philadelphia, PA, at the University of Pennsylvania.
