from From 'sprint,' which shows up in English in the 1500s meaning to run swiftly, likely from Old Norse 'spretta' — to jump up or spring forth. The '-er' just bolted on the agent suffix, turning the action into a job description. The root sense of a sudden, sprung release still fits: something coiled, then let go all at once.
