Pig in a poke

The idioms pig in a poke and sell a pup (or buy a pup) refer to a confidence trick originating in the Late Middle Ages, when meat was scarce, but cats and dogs were not.^[1][2][3] The scheme entailed the sale of a suckling pig in a poke. The bag, sold unopened, would actually contain a cat or dog, which was substantially less valuable as a source of meat. The French idiom acheter (un) chat en poche (to buy a cat in a bag) refers to an actual sale of this nature, as do many European equivalents, while the English expression refers to the appearance of the trick.^[4]

Etymology

In the past, it was common for small farmers to put a pig in a cloth sack to bring it to market for sale. A poke is a sack or bag. It has a French origin as poque and, like several other French words, its diminutive is formed by adding -ette or -et — hence pocket began life with the meaning "small bag". Poke is still in use in several English-speaking places, including Scotland and some regions of the United States. For example, among English hop growers, a poke is a large sack into which hops are poured to be taken from the picking machine to the oast for drying.

The full maxim is "don't buy a pig in a poke". This is addressed in the common law by guaranteeing a buyer the right to inspect goods before purchase, as in Gardner v Gray(1815).^[5][6]

Relation to other idioms and expressions

The English colloquialisms such as turn out to be a pig in a poke or buy a pig in a poke mean that something is sold or bought without the buyer knowing its true nature or value, especially when buying without inspecting the item beforehand. The phrase can also be applied to accepting an idea or plan without a full understanding of its basis. Similar expressions exist in other European languages, most of them referring to the purchase of a cat in a bag.

This trick may be the origin of the expression "letting the cat out of the bag",^[7] meaning to reveal that which is secret (if the would-be buyer opened the bag, the trick would be revealed).^[4]

Use in popular culture

In the April 1929 edition of the literary magazine London Aphrodite, a story by Rhys Davies, titled "A Pig in a Poke", was published, in which a Welsh collier takes a woman from London for his wife and regrets it.^[8] (Boulton 1993: p. 278)

The title of Georges Feydeau's 1888 play Chat en poche is taken from the French expression.
