   {To have the advantage of} (any one), to have a personal
      knowledge of one who does not have a reciprocal knowledge.
      ``You have the advantage of me; I don't remember ever to
      have had the honor.'' --Sheridan.

   {To take advantage of}, to profit by; (often used in a bad
      sense) to overreach, to outwit.

   Syn: {Advantage}, {Advantageous}, {Benefit}, {Beneficial}.

   Usage: We speak of a thing as a benefit, or as beneficial,
          when it is simply productive of good; as, the benefits
          of early discipline; the beneficial effects of
          adversity. We speak of a thing as an advantage, or as
          advantageous, when it affords us the means of getting
          forward, and places us on a ``vantage ground'' for
          further effort. Hence, there is a difference between
          the benefits and the advantages of early education;
          between a beneficial and an advantageous investment of
          money.
