early 14c., "keep in mind, retain in the memory," from Old French remembrer "remember, recall, bring to mind" (11c.), from Latin rememorari "recall to mind, remember," from re- "again" (see re-) + memorari "be mindful of," from memor "mindful" (see memory). Meaning "recall to mind" is late 14c.; sense of "to mention" is from 1550s. Also in Middle English "to remind" (someone). An Anglo-Saxon verb for it was gemunan.
