The source of the word travel may be lost to history. The word travel could be derived in the Old French work, or labor. Merriam Webster's dictionary reveals that the first known usage of the word "travel" dates from the 14th century. According to the dictionary, the word originates in Middle English travailen, travelen (which means to torment, labor, strive travel, torment) and earlier originated from Old French travailler (which means to work strenuously, toil). The word is still used to describe the work, fight, or labor in English. Simon Winchester's The Best Travelers' Tales of 2004 states that "travel" and "trouble" both have a earlier and more ancient ancestry. The tripalium is a Roman device for torture, is the source of these terms. Traveling in the present can be easy or difficult, depending on the destination. Travel to Mount Everest, the Amazon rainforest, extreme tourism, and adventure tourism are the more challenging kinds of travel. It isn't always easy to travel by cruise ship or bus.
