Pale is an old name for a pointed piece of wood driven into the ground and â by an obvious extension â to a barrier made of such stakes, a palisade or fence. Pole is from the same source, as are impale, paling and palisade. This meaning has been around in English since the fourteenth century and by the end of that century pale had taken on various figurative senses â a defence, a safeguard, a barrier, an enclosure, or a limit beyond which it was not permissible to go.
