Mid 16th century (as a verb): imitative, perhaps of Scandinavian origin.

  • jump from early 16th century:

    Like bump (mid 16th century) and thump (mid 16th century), jump was probably formed because it ‘sounded right’, and seemed to express the sound of feet hitting the ground. It was first used around 1500. To jump the gun, or act too soon, comes from the idea of an athlete starting a race a split-second before they hear the starting gun. A jumpsuit was a term first used in the USA in the 1940s for the outfit worn by parachutists when making their jumps. Jumper (mid 19th century) is unrelated. In the 19th century it was a loose outer jacket worn by sailors and is now a woollen jersey in UK English, but a style of dress in the USA. It may come from Scots jupe, ‘a loose jacket or tunic’, which in turn came through French from Arabic jubba.
