Notes :The root has an old suffixal -l- which is also seen in several other cases. It may be bisyllabic, but this is hard to prove. The causative form ('to winnow') was *ed_-l-c- > Konda er_lis-, PK *ēRs- (original alveolar phoneme preserved because of *-l-; without it *eh- would be expected). PPM *zēc- > Pengo jēc- has NOTHING! NOTHING! to do with this!!!
