Etymology: "Over" comes from Old English "ofer," which meant "above" or "across" long before it came to suggest excess. "Guard" is a French-shaped cousin of "ward." Old English had "weard" for a watchman or protector, from a Germanic root meaning to watch over. After the Norman Conquest, Anglo-Norman speakers used "garder," from Old French, which shared that origin, and English absorbed it alongside the native form. Words like these, which share a root but arrived by different routes, are called doublets, and they explain why "ward" and "guard" sound so different yet mean much the same. Joined together, the compound describes a guard set above or across something to shield it. Because it is a transparent combination of two familiar parts, it needed no special coinage, and its date of first use is uncertain.
