Etymology
Unclear. Usually two theories are proposed:
 * Past passive participle of unattested verb (nouns:, ) that is the exact equivalent of the 🇨🇬. This etymology is supported by analogies, cf. > . Cognate with 🇨🇬.
 * Past passive participle of . This etymology is supported by the fact that in many beliefs, evil spirits were often mutilated, cf. 🇨🇬, 🇨🇬 from 🇨🇬. Relation with, , , is also possible.

Other propositions include:
 * Berneker: past passive participle of unattested verb that is the exact equivalent of the 🇨🇬 from 🇨🇬 (or ) with literal meaning “avenger”. Bezlaj derives it from the same root, but through a different semantic shift: “astride, askew” → “evil, treacherous”.
 * From though a semantic development “quick” → “scary, freakish”.

Modern descendants are sometimes associated through folk etymology with (descendants of) 🇨🇬.
