  • 10th-century Byzantine: /am.niˈsi.a/[1]

Forms

ἀμνησία (amnēsía) f (genitive ἀμνησίᾱς); first declension[1]

Etymology

It is formed as if from an adjective “forgetful”, from Ancient Greek ἀ- (a-) + μιμνήσκω (mimnḗskō) + -ία (-íā) “to remind”.[1][2] Babiniotis derives it from the privative ἀ- and the stem of μνήμη (mnḗmē) “memory”.[3] Etymonline traces that stem to the root Proto-Indo-European *men- (“to think”).[4]

The usual Greek word was ἀμνηστία (amnēstíā), but it had taken the special sense of forgetting past wrongs, an amnesty.[4]

Earliest recorded meaning

It is first found in the Septuagint translation of Sirach (2nd century BC), in the phrase ἀμνησία κακῶν “forgetting of ills”.[5][6][7]

Semantic evolution

The Wisdom of Solomon also uses it for forgetfulness, as a synonym of λήθη (lḗthē).[6][7] A papyrus from Oxyrhynchus uses it for a decree of amnesty.[6][5] LSJ dates it to the 3rd century AD,[6] but the DGE dates it to the 3rd century BC.[5] The word is rare in the ancient texts.[7]

Modern Latin took it up as a medical term, and English amnesia has meant “loss of memory” since 1786.[4] Modern Greek αμνησία (amnisía) is a learned word, reintroduced with its medical sense under the influence of French amnésie.[8][3]
