   Usage: Obstruction, Obstacle. The difference between
          these words is that indicated by their etymology; an
          obstacle is something standing in the way; an
          obstruction is something put in the way. Obstacle
          implies more fixedness and is the stronger word. We
          remove obstructions; we surmount obstacles.
          [1913 Webster]

                Disparity in age seems a greater obstacle to an
