Etymology
the compound noun "jump-off" is a transparent formation from the verb "jump" and the particle "off." its core logic is spatial and metaphorical: a literal leap away from a starting point. this evolved into signifying the decisive moment an action or phase commences. in competitive contexts, particularly equestrian sports, it specifically denotes the extra round that "jumps off" from the main competition to decide a winner, perfectly encapsulating the idea of a decisive beginning sprung from a previous deadlock.
Analysis
jump (from middle english 'jumpen', likely of onomatopoeic origin, meaning to spring into the air). off (from old english 'of', meaning away, away from, indicating separation or point of origin).
