ἀλᾱθάς (alāthás) — Doric

Etymology

In form it would be from ἀ- (a-, “un-”) + *ληθής (*lēthḗs), from *λῆθος (*lêthos, “concealment, forgetfulness”) + -ής (-ḗs), the former component from λήθη (lḗthē, “oblivion, forgetfulness”), thus "unconcealed, unforgotten"; see the latter for more.^[1] Compare also λήθω (lḗthō), λανθάνω (lanthánō).

Adjective

ᾰ̓ληθής • (ălēthḗs) m or f (neuter ᾰ̓ληθές); third declension

(of things) true, real, genuine

- 385 BCE – 380 BCE, Plato, Symposium 217e:
