Word History: A pig in a poke is a colorful vernacular expression used to describe something offered in a manner that conceals its true nature or value. Naturally, a buyer cannot inspect the pig if it is covered by a poke—that is, a bag or sack. The word poke meaning "bag" is not confined to just the American South—in many parts of Scotland, poke bag is still used of a little paper bag for carrying purchases like candy. Poke first appears in English in the 1200s and probably comes from Old North French, the northern dialect of Old French. The Old North French word in turn is probably of Germanic origin and is related to words like Icelandic poki, "bag." Poke has several relatives within English. The word pocket comes from Middle English poket, meaning "pouch, small bag," which in turn comes from Anglo-Norman pokete, a diminutive of Old North French poke. Pouche, a variant form of Old North French poke, is the source of the English word pouch.
