Etymology: "Opsony" is a rare economics term, and its history runs back to a Latin word for food. Latin "obsonium" meant the food or provisions bought for a meal, especially fish and other relishes eaten with bread. The Greek root behind it, "opsōnion," had the same sense, which is why the word has long been tied to the idea of purchasing. The English term, used for a market in which a single buyer holds power over prices, is a modern coinage built on that ancient root. Its meaning sits at a sharp remove from the Roman dinner table: where "obsonium" described what a household bought for its meals, "opsony" describes a market shaped by one purchaser rather than by many sellers and buyers. The link between the two is simply the act of buying.
