Комментарии:Kuwi_D and Kuwi_P probably reflect an earlier variant of this bisyllabic root, namely, *elimbu. This is quite understandable for Kuwi_D - an extremely archaic dialect which has preserved old bisyllabic roots in a much better state than others, but unexplainable for Kuwi_P; we may suggest dialectal interaction. Inlaut -mp- in some dialects is not quite clear as well.
