The origins of the word "travel" are probably lost to time. In the Old French term travail means "work". Merriam Webster's dictionary reveals that the first recorded usage of the word "travel" dates in the 14th century. It also states that the word originates in Middle English travailen, travelen (which is a reference to torture and torment, work, struggle, journey) and earlier from Old French travailler (which means to exert effort, work). It is also known as toil, or work. English there are still instances when people use the words travail, meaning struggle.

This could be an indication of the difficulties of traveling the ancient world. Based on the place the travel experience in contemporary times can or cannot be made more simple. Mount Everest, Amazonian rainforests as well as extreme tourism and adventure are among the most difficult types of travel. The journey can become even more difficult if you travel in an alternative manner, for example via ship, bus, or even by bullock carts.
