Middle English: from Old Northern French planke, from late Latin planca 'board', feminine (used as a noun) of plancus 'flat-footed'.

  • The word plank ultimately comes from Latin planca ‘a board or slab’. Britons have been calling less bright people planks since the early 1980s, from the phrase as thick as two planks or two short planks, recorded from the previous decade. Walking the plank is a method of execution associated with pirates although there is little evidence that this was done regularly, and most pirates probably just threw their victims overboard.
