When referring to an establishment that sells alcoholic drinks, what is the word “pub” short for?

A pub (short for public house) is a drinking establishment licensed to serve alcoholic drinks for consumption on the premises. The term first appeared in the late 17th century, and was used to differentiate private houses from those which were open to the public as alehouses, taverns and inns.

The history of pubs can be traced to taverns in Roman Britain, and through Anglo-Saxon alehouses, but it was not until the early 19th century that pubs, as they are today, first began to appear. The model also became popular in countries and regions of British influence, where pubs are often still considered to be an important aspect of their culture. In many places, especially in villages, pubs are the focal point of local communities. In his 17th-century diary, Samuel Pepys described the pub as "the heart of England".

Although the drinks traditionally served include draught beer and cider, most also sell wine, spirits, tea, coffee, and soft drinks. Many pubs offer meals and snacks, and so-called gastropubs serve food in a manner akin to a restaurant.
