Etymology: Economists needed a word for the mirror image of monopoly, and they built it from two Ancient Greek pieces. "Oligoi" means "few," and "opsonia" means "purchase," so the result describes a market where a handful of buyers hold the power over many sellers. The Greek "opsonia" is itself a striking word: it originally meant the buying of provisions, particularly food to be eaten with bread, and the verb "opsoneo" meant to buy or provide victuals. The coinage follows the familiar pattern of monopoly, which joins "monos" (one) to the same "-polia" element meaning selling. Oligopsony swaps in "few" and a buying-focused root, so the pair shows the structure of market power from the seller's side and the buyer's side. The word is a modern technical formation built from classical roots, not a term that ancient Greeks used for economic conditions.
