Comment: 2d class marker in PL; tends to shift to 1t class (note that Tab. d- actually reflects 4th class *d-). It's unique phonetic nature (initial *r-, otherwise possible in PL only from *Hr- clusters) suggests that it is < *jV-r- (where *j is the original 2d class marker, while -r- was introduced from the original 4th class).
