means A person who travels to a place for pleasure or sightseeing, typically for a short stay.

from From the French 'tour' — a turn, a circuit, a going-around — which traces back through Old French to the Latin 'tornus,' a lathe or turning-tool (itself borrowed from Greek 'tornos'). The idea is of a journey that loops out and circles home again, a 'tour.' English fitted the agent-suffix '-ist' onto it around the late 18th century, just as leisure travel was becoming a fashionable circuit for those with money to spend — the original 'tourist' being someone making the rounds, not the one-way wanderer.
