shot: [OE] Shot goes back to a prehistoric Germanic *skutaz, which was derived from the same base that produced English shoot. It used to mean ‘payment’ as well as ‘act of shooting’, a sense shared by its Old Norse relative skot, which provided English with the scot of scotfree [16] (etymologically ‘without having to pay’). => scot-free, shoot[shot etymology, shot origin, 英语词源]
