Definition of duplicate

du´pli`cate

Duplicate proportion
(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.

That which exactly resembles or corresponds to something else; another, correspondent to the first; hence, a copy; a transcript; a counterpart.

I send a duplicate both of it and my last dispatch.

- Sir W. Temple.

(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.

v. t.

To double; to fold; to render double.

[imp. & p. p. Duplicated ; p. pr. & vb. n. Duplicating.]

To make a duplicate of (something); to make a copy or transcript of.

(Biol.) To divide into two by natural growth or spontaneous action; as, infusoria duplicate themselves.
