'anamnestically' originates from Greek, specifically the word 'anamnēstikos,' where 'ana-' meant 'again' and 'mimnēskein' meant 'to remember.'

'anamnēstikos' changed from the Greek word to the Late Latin 'anamnesticus,' and eventually became the modern English word 'anamnestic,' from which 'anamnestically' is derived.

Initially, it meant 'pertaining to recollection or memory,' and this meaning has remained consistent in modern usage, especially in medical contexts.
