Etymology
The origin has been considered. NHB compares to 🇨🇬, passive participle of. A better comparison is 🇨🇬, passive participle of from the root  which is well-used in various forms though this passive participle is hardly known because the active participle  or rather the – lexicalized – adjective form  is expected, likely cognate to 🇨🇬 also with many formations in its root, pars pro toto for all 🇨🇬 languages as this root is widely present in Ethiopian and 🇨🇬 where the root has been borrowed from Ethiopian. For the sound correspondence note that the classical dictionaries also list and  as dialectal variants of.

Note also 🇨🇬, from the root of.

Under both theories, 🇨🇬 and, likely foreign borrowings, might be related.
