Etymology
May be from, if related to the first component of 🇨🇬, from a root  whence also 🇨🇬, 🇨🇬, 🇨🇬 (< 🇨🇬) and possibly 🇨🇬 (if earlier ). However all of the supposed Indo-European cognates are of origin, and according to Kroonen this fact along with the root-noun inflection may be indicative of a non-Indo-European  origin; compare also 🇨🇬.
