ORIGIN
Early 17th century (as a noun): of unknown origin; perhaps related to skate.
The sense 'render temporarily harmless' is based on a passage in Shakespeare's Macbeth: ‘We have scotch'd the snake, not kill'd it’; the sense 'put an end to' (early 19th century) results from the influence on this of the notion of wedging or blocking something so as to render it inoperative.
