Definitions

1. A type of equestrian jump consisting of two vertical elements set close together to broaden the obstacle ; a device in horse jumping to increase the difficulty by requiring greater width clearance ; an obstacle used in show jumping involving two parallel bars to test the horse's ability to clear a wider jump
2. A jumping fence composed of two upright poles arranged to form a spread that demands a longer leap ; an apparatus in competitive horseback riding that challenges the breadth of the jump ; equipment used in horse jumping events to create a wider barrier for the horse to clear
3. An equestrian obstacle featuring two vertical rails set side by side creating a double-width jump ; a structure designed to test riders' and horses' jumping range by combining two fences ; a competition element in show jumping that extends the fence’s horizontal distance to heighten complexity

Etymology: The origin of this term is not firmly established. The most plausible guess links it to "ox," with an agent-style ending, pointing to a barrier built from heavy rails of the kind used to fence cattle. That idea is attractive, but the early records that would confirm it are not available here, so it remains a likely explanation rather than a proven one. What is clear is what the object does. The jump is built from two uprights set a distance apart, so the horse must clear both width and height. That spread is the feature that gives the obstacle its character, and it is the reason the term refers to a specific kind of barrier rather than any fence.

Synonyms: jump, obstacle, fence, equestrian jump
