The source of the word travel is most likely forgotten to the past. The term travel may have been derived from Old French travail (which means work). The Merriam-Webster Dictionary states that travel was first mentioned in the 14th Century. The dictionary says that the word travel originates in Middle English (which is tormenting, striving, and toiling) in addition to Old French (which was toil). The word is still used to describe the work, torment, struggle or work in English. Simon Winchester's novel The Best Travelers' Tales 2004 states that both travel and work have a more ancient source. It can be traced back to Roman tripalium which was an instrument used to torture the Romans. Traveling today is either easier or more difficult dependent on the place you travel to. Mount Everest, Amazonian rainforests extreme tourism, and adventures are some of the most challenging kinds of travel. The journey can become even more difficult if you travel in a different manner, for example by bus, ship, or even by bullock carts.
