The origin of the word travel has been forgotten to the past. It's possible that concept of travel is derived from the Old French word called travail which means "work". Merriam Webster declares that it was in the 14th century that the term "travel" was first popularized. The dictionary of Merriam-Webster also states it is derived from Middle English travelen and travailen (which means to torture or toil in order to accomplish a goal, struggle, or journey) in addition to Old French travail (which meant to strive to accomplish a task, work hard, or toil). In English there is a tendency to use"work" which is also a reference to an effort. Simon Winchester's novel The Best Travelers' Tales 2004 declares that travel and labor have a much older root. This can be traced back to Roman tripalium citation required - a torture tool used by the Romans. Traveling in the present can be straightforward or complicated, depending on the destination.
