καθαρός

• κοθᾰρός (kotharós) — Doric
• κόθᾰρος (kótharos) — Aeolic

No suitable Indo-European cognates can be drawn; the traditional connection to Sanskrit शिथिर (śithira, “loose, relaxed”) requires too many ad hoc assumptions, both phonetic and semantic. This, along with α/ο variation, implies a borrowing from Pre-Greek.^[1]
