ἀκορέστατος, "most insatiate" (κόρος); hence, reckless of due limit,— shameless: cp.
. Eur. Her. 926 (deprecating ὕβρις), “μήποτ᾽ ἐμὸν φρόνημα
ψυχά τ᾽ ἀκόρεστος εἴη
”. A positive ἀκορής is found in later Greek (Themistius, or. 90 D, 4th cent. A.D.): and as διακορής and κατακορής are classical (Plato, etc.), it may be a mere accident that ἀκορής has no earlier warrant. If referred to ἀκόρεστος, the superl. would be a poet. form like νέατος, μέσατος.
