Reconstruction:Proto-Germanic/kalbaz

Etymology
. The connection with is problematic due to the missing labiovelar in Germanic. However, *gʷl̥bʰus- or the weak stem of *gʷélbʰ-us ~ *gʷl̥bʰ-éws would yield *kulbuz-, from which the variant *kelbuz-, also attested in Germanic, could have been derived analogically as a strong stem, whose influence might explain the missing labialization in *kalbiz-.

Pokorny connects it to 🇨🇬, itself perhaps of 🇨🇬 origin, and proposes as a labial extension of ; compare 🇨🇬 (modern 🇨🇬), 🇨🇬, 🇨🇬, and 🇨🇬,. However, such irregular correspondences between and  would more likely point to  origin.

Has been compared to 🇨🇬, itself of uncertain origin.
