Duplicate \Du"pli*cate\, n.
   1. That which exactly resembles or corresponds to something
      else; another, correspondent to the first; hence, a copy;
      a transcript; a counterpart.

                                                  -- Sir W.
                                                  Temple.

   2. (Law) An original instrument repeated; a document which is
      the same as another in all essential particulars, and
      differing from a mere copy in having all the validity of
      an original. --Burrill.

Duplicate \Du"pli*cate\, v. t. [imp. & p. p. {Duplicated}; p.
   pr. & vb. n. {Duplicating}.]

   to double, fr. duplex double, twofold. See {Duplex}.]
   Double; twofold.

   {Duplicate proportion} or {ratio} (Math.), the proportion or
      ratio of squares. Thus, in geometrical proportion, the
      first term to the third is said to be in a duplicate ratio
      of the first to the second, or as its square is to the
      square of the second. Thus, in 2, 4, 8, 16, the ratio of 2
      to 8 is a duplicate of that of 2 to 4, or as the square of
      2 is to the square of 4.
