More about uraeus
Uraeus, “the sacred asp on ancient Egyptian headdresses,” comes from Late Greek ouraîos, of the same meaning. This ouraîos appears identical to Ancient Greek ouraîos, “of the tail,” but the two likely do not share a deeper origin; while ouraîos, “of the tail,” comes from ourá, “tail,” and is the source of the English combining form uro- (not to be confused with oûron, “urine,” the source of a different uro-), ouraîos, “uraeus,” comes from Egyptian y’rt, “rearing cobra,” which is also transliterated variously as iaret or jꜥrt. Though uraeuses is the standard plural, the alternative uraei appears in some texts. Uraeus was first recorded in English circa 1830.
