arguo

Often taken to be a denominative verb 'to make bright, enlighten' to Proto-Italic *argu- (“bright”), from Proto-Indo-European *h₂érǵus (“white”), from *h₂erǵ-. Thus cognate with Ancient Greek ἄργυρος (árguros) and Hittite 𒄯𒆠𒅖 (ḫarkiš, “bright, white”). If so, compare English declare (literally “to make clear”) for the sense development.^[1]

Duchesne-Guillemin, Laroche and Melchert reject the above etymology and instead compare arguo with the semantically better-fitting Hittite [script needed] (arkuwā(i)-, “state one's case, make a plea”). (Can this⁽⁺⁾ etymology be sourced?)
