HARRIS et al. Trapped morphologyThe research reported here was supported in part by the National Science Foundation under Grant Number BCS-0215523 (ACH) and by the Centre for Advanced Study in Oslo in 2005 (both authors). We are grateful to our colleagues at the Centre for Advanced Study for their comments, especially to Henning Andersen for help with the Slavic data. We also appreciate comments and challenges from members of the audience at the workshop Weak Words: Their Origin and Progress, held in Konstanz in April 2005, where an earlier version of this paper was presented. We would also like to thank Brian Joseph for discussion of the Greek data.
