1772 and tourism in 1811. These words derive from the word tour, which comes from Old English , from Old French , from Latin - "to turn on a lathe", which is itself from Ancient Greek () - "lathe". Definitions In 1936, the League of Nations defined a foreign tourist as "someone traveling abroad for at least twenty-four hours". Its successor, the United Nations, amended this definition in 1945, by including a maximum stay of six months. In 1941, Hunziker and Kraft defined tourism as "the sum of the phenomena and relationships arising from the travel and stay of non-residents, insofar as they do not lead to permanent residence and are not connected with any earning activity." In 1976, the Tourism Society of England's definition was: "Tourism is the temporary, short-term movement of people to destinations outside the places where they normally live and work and their activities during the stay at each destination. It includes movements for all purposes." In 1981, the International Association of Scientific Experts in Tourism defined tourism in terms of particular activities chosen and undertaken outside the home. In 1994, the United Nations identified three forms of tourism in its Recommendations on Tourism Statistics: Domestic tourism, involving residents of the given country traveling only within this country Inbound tourism, involving non-residents traveling in the given country Outbound tourism, involving residents traveling in another country Other groupings derived from the above grouping: National tourism, a combination of domestic and outbound tourism Regional tourism, a combination of domestic and inbound tourism International tourism, a combination of inbound and outbound tourism The terms tourism and travel are sometimes used interchangeably. In this context, travel has a similar definition to tourism but implies a more purposeful journey. The terms tourism and tourist are sometimes used pejoratively, to imply a shallow interest in the cultures or locations visited. By contrast, traveller is often used as a sign of distinction. The sociology of tourism has studied the cultural values underpinning these distinctions and their implications for class relations.
