porterhouse

The word "porterhouse" is a compound formed from two native English elements, "porter" and "house." Its primary modern meaning, referring to a specific cut of steak, is a fascinating semantic shift from its original 18th-century sense. Initially, a porterhouse was an establishment akin to a tavern or alehouse, named for its primary product, "porter"—a dark, hoppy beer popular with street and river porters. By the mid-19th century, the name became associated with a particular New York City eating house, the Porter House, which was famous for serving generous meals, including substantial steaks. Over time, the term transferred from the establishment itself to its signature dish, solidifying in American English to denote the large, T-bone steak cut we know today.

Structure: porter + house porter: From Middle English porter, from Old French portour (a carrier, gatekeeper), from Late Latin portator, from Latin portare (to carry). In this compound, it refers to the dark beer called "porter." house: From Old English hūs (a dwelling, shelter, building), from Proto-Germanic hūsą. It functions as the head noun denoting a building or establishment.
