A langue or tongue (Italian: lingua) was an administrative division of the Knights Hospitaller (also known as the Order of St. John of Jerusalem) between 1319 and 1798. The term referred to a rough ethno-linguistic division of the geographical distribution of the Order's members and possessions. Each langue was subdivided into Priories or Grand Priories, Bailiwicks and Commanderies, and was responsible for a certain sector in their administration. Each langue had an auberge as its headquarters, some of which still survive in Rhodes, Birgu and Valletta.
