The source of the word travel has been not known to historians. It's possible that the word travel originates from an Old French word called travail that translates to "work". According to the Merriam-Webster Dictionary, the word travel first came into use in the 14th Century. The Merriam-Webster dictionary also says it is derived in Middle English travelen and travailen (which mean to torment or labor in order to reach a target such as a journey, battle, or struggle) and Old French travail (which meant the effort required to complete an objective, to work or work hard). People still use the word struggle, or travail in English. Simon Winchester writes in The Best Travelers' Tales (2004) that travail and travel are both derived from a prior time: the Roman torture apparatus known as the tripalium. The modern travel experience can differ in the difficulty based on where you are. Mount Everest is a more demanding destination to travel. It is also a difficult destination to travel through.
