COMMENT: An expressive root, however, surprisingly similar in distant subgroups and thus probably archaic. Most EC languages reflect a variant with an expressive suffix *-dV (*gäldV).
Some other forms with an expressive shift *g > *ʁ can also be related: cf. Ing. ʁadaʁilg(aš), Tab. ʁIudʁIli, Lak. ʁIidi. Unfortunately the root is recorded only in few EC languages.
