COMMENT: PWC reflects the root with loss of labialisation; otherwise all the correspondences are regular. The root was obviously denoting a small bird in PNC; the shift to "eagle" in PD is a result of development "small bird" > "bird (in general)" (as in some Lezg. languages) > "bird par excellence" = "eagle". In any case the Darg. form is impossible to separate from this root.
