'tourism-related' originates from the combination of 'tourism' and 'related', where 'tourism' refers to the business of providing services to tourists and 'related' means connected or associated.

'tourism' evolved from the French word 'tourisme', and 'related' comes from the Latin 'relatus', meaning 'brought back'.

Initially, 'tourism' referred to the act of traveling for pleasure, and 'related' meant connected. Together, they now describe anything associated with the tourism industry.
