   1. To keep back; to retain; not to deliver, make over, or
      disclose. "I have reserved to myself nothing." --Shak.

   Note: In cases where one person or party makes a request to
         an agent that some accommodation (such as a hotel room
         or place at a restaurant) be kept (reserved) for their
         use at a particular time, the word reserve applies both
         to the action of the person making the request, and to
         the action of the agent who takes the approproriate
         action (such as a notation in a book of reservations)
         to be certain that the accommodation is available at
         that time.
