mere

At first, mere had nothing to do with smallness. In Latin, merus meant “unmixed”—wine without water, gold without alloy—and possibly reached that idea through an older image of something gleaming cleanly, like a bright metal surface. French mier carried the word into English, where mere could mean “absolute” or “complete”: mere folly once meant something like “sheer folly,” not “only a little folly.” By the 1580s, English speakers had turned the emphasis around, using mere for “nothing more than,” as in a mere dream. There is also a Germanic look-alike behind older mere: Old English mǣre could mean “splendid” or “a boundary,” so several words may have converged in medieval English, leaving us with a tiny word carrying both a polished-gold history and the notion of a limit. Think of mere as a verbal measuring line: it can mark the absolute edge of something—or tell you that there is nothing beyond it.
