1580s, "act of remembering," from Middle French reminiscence (14c.) and directly from Late Latin reminiscentia "remembrance, recollection" (a loan-translation of Greek anamnesis), from Latin reminiscentem (nominative reminiscens), present participle of reminisci "remember, recall to mind," from re- "again" (see re-) + minisci "to remember," from root of mens "mind," from PIE root *men- "mind, understanding, reason" (see mind, n.). Meaning "a recollection of something past" is attested from 1811.
