Rule \Rule\, n.

   {Rule of the road} (Law), any of the various regulations
      imposed upon travelers by land or water for their mutual
      convenience or safety. In the United States it is a rule
      of the road that land travelers passing in opposite
      directions shall turn out each to his own right, and
      generally that overtaking persons or vehicles shall turn
      out to the left; in England the rule for vehicles (but not
      for pedestrians) is the opposite of this. Run \Run\, n.
   1. (Piquet, Cribbage, etc.) A number of cards of the same
      suit in sequence; as, a run of four in hearts.

   2. (Golf)
      (a) The movement communicated to a golf ball by running.
      (b) The distance a ball travels after touching the ground
          from a stroke.
