The origins of travel were lost in time. It is possible that the word travel originates from the Old French word called travail which means "work". Merriam Webster says that the 14th century was in which the phrase "travel" was first popularized. The Merriam-Webster dictionary also says that it comes from Middle English travelen and travailen (which means to torture or toil in order to achieve a goal such as a journey, battle, or struggle), as well as Old French travail (which meant to strive to accomplish an objective, to work, or toil). In English people sometimes employ the term "work" to refer to struggles. Simon Winchester's novel The Best Travelers' Tales, 2004, states that both travel and travail have an even older source. It is the Roman tripalium citation required - a torture tool used by the Romans. Modern travel could be as easy, based on the location.
