Ordinate \Or"di*nate\, a. [L. ordinatus, p. p. of ordinare. See
   {Ordain}.]
   Well-ordered; orderly; regular; methodical. ``A life blissful
   and ordinate.'' --Chaucer.

   {Ordinate figure} (Math.), a figure whose sides and angles
      are equal; a regular figure.

Ordinate \Or"di*nate\, n. (Geom.)
   The distance of any point in a curve or a straight line,
   measured on a line called the axis of ordinates or on a line
   parallel to it, from another line called the axis of
   abscissas, on which the corresponding abscissa of the point
   is measured.

   Note: The ordinate and abscissa, taken together, are called
         co["o]rdinates, and define the position of the point
         with reference to the two axes named, the intersection
         of which is called the origin of co["o]rdinates. See
         {Coordinate}.

Ordinate \Or"di*nate\, v. t.
   To appoint, to regulate; to harmonize. --Bp. Hall.
