'amnesic' originates from Greek, specifically the word 'amnesia,' where 'a-' meant 'not' and 'mnasthai' meant 'to remember.'

'amnesia' transformed into the English word 'amnesic' to describe a state or condition related to memory loss.

Initially, it meant 'not remembering,' but over time it evolved into its current meaning of 'relating to or suffering from amnesia.'
