Etymology

The term "round-trip" combines "round," from Old English rund (meaning "circular" or "complete"), and "trip," from Middle Dutch trippen (meaning "to skip" or "journey"). It emerged in the 19th century to describe a completed journey (to a destination and back), emphasizing the cyclical nature of the travel. The logic mirrors the physical act of returning to the starting point, hence "round" (full circle) + "trip" (movement).
