History has most likely forgotten the origin of travel. The word travel could have come from the Old French travail (which means work). Merriam Webster declares that it was the 14th-century in which the phrase "travel" was first popularized. According the Merriam-Webster Dictionary the word "travel" is derived of Middle English Travailen, Travelen (which means labor, struggle or travel), and Old French Travail (which means working with a lot of effort, toil). The word "work" is used to describe the effort, or work. English people sometimes employ the term "work" to describe the struggle. Simon Winchester, in The Best Travelers' Tales 2004 says that the word travel comes from an early Roman torture instrument called tripalium. This could be a reflection of travel difficulties in the world of antiquity. Modern travel could be much easier, depending on where you are going. Mount Everest, Amazonian rainforests as well as extreme tourism and adventure are some of the most difficult kinds of travel. It can be even harder if you travel in a different manner, for example by bus, ship, or even by bullock carts.
