Generally the first expresses something arising from the nature and circumstances of the affair; the second something arising from a foreign cause. An obstruction blocks the passage, and is generally put in the way intentionally. An impediment literally clogs the feet and so may continue with one, hindering his progress, while a difficulty once overcome, an obstacle once surmounted, or an obstruction once broken down, leaves one free to go forward without hindrance.
