Word Origin & Etymology

The noun dates to the late 15th century, likely derived from Anglo-French 'escopir' (to spit out), referring to the way water is expelled from a ship's deck. The verb sense of sinking a ship arose in late 19th-century naval slang and later broadened in British English to mean ruining a plan.
