The Merriam-Webster Dictionary states that the term travel first appeared around the 14th century. This dictionary states that travel comes in Middle English (which is tormenting struggling, toiling, or striving) as well Old French (which was toil). People still use the word torment, struggle or work in English. Simon Winchester's book The Best Travelers' Tales 2004 says that travel as well as travail have an even older root.
