Tourism has been defined by World Trade Organisation (WTO) as “movement of people away from their normal place of residence and work for a period of not less than 24 hours and more than 1 year”. Tourism is travel for recreational, leisure or business purposes. Theobald (1994) suggested that "etymologically, the word tour is derived from the Latin, 'tornare' and the Greek, 'tornos', meaning 'a lathe or circle; the movement around a central point or axis'. This meaning changed in modern English to represent 'one's turn'. The suffix –ism is defined as 'an action or process; typical behaviour or quality', while the suffix, –ist denotes 'one that performs a given action'. When the word tour and the suffixes –ism and –ist are combined, they suggest the action of movement around a circle. One can argue that a circle represents a starting point, which ultimately returns back to its beginning.
