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 The series has included volumes of previously unpublished work, or work in progress, by linguists with an ongoing affiliation with the Department, as well as volumes of papers from NWAV and the Penn Linguistics Conference. This volume contains selected papers from New Ways of Analyzing Variation 44 (NWAV 44), held October 22–25, 2015 at the University of Toronto.
