Etymology

The word "reminder" originates from the combination of the prefix "re-" (meaning "again"), the root "mind" (from Old English "gemynd," meaning "memory" or "thought"), and the agentive suffix "-er." The term evolved in Middle English to denote something or someone that brings a thought or memory back to attention. The logic follows a clear progression: "re-" (repetition) + "mind" (mental focus) + "-er" (thing/person performing the action).
