It is likely that the roots of travel were lost in time. The word travel could have originated from Old French travail (which means work). Merriam Webster declares that it was in the 14th century in which the phrase "travel" was first popularized. The dictionary of Merriam-Webster also states that the word comes from Middle English travelen and travailen (which mean to torment or work to reach a target (or journey) and Old French travail (which meant the effort required to complete the task at hand, do hard work, or toil). The word "work" is used to mean to work hard, laborious. English, people still occasionally use the words travail, meaning struggle. Simon Winchester's novel The Best Travelers' Tales 2004 states that both travel and labor have a much older roots. It can be traced back to Roman tripalium, a citation for a tripalium that was an instrument used to torture the Romans. Traveling today can be easier or harder dependent on the place you travel to.
