porkpie

The word 'porkpie' is a transparent English compound noun formed from two established nouns: 'pork' and 'pie'. 'Pork' entered English via the Norman French porc, tracing back to the Latin porcus for a domesticated pig, reflecting the culinary distinction where the animal's meat is named with a French-derived term. 'Pie' has a more obscure history, possibly linked to the Medieval Latin pīca, referring to a baked dish with a mixed filling. The term first literally described a pie containing pork. In the mid-19th century, the name was transferred to a style of hat whose low, flat, circular crown was thought to resemble the shape of such a pie, demonstrating a classic metonymic shift from a food item to an object of similar form.
