Curvature Cur"va*ture (k?r"v?-t?r; 135), n. [L. curvatura. See {Curvate}.] 1. The act of curving, or the state of being bent or curved; a curving or bending, normal or abnormal, as of a line or surface from a rectilinear direction; a bend; a curve. --Cowper. [1913 Webster]

The elegant curvature of their fronds. --Darwin. [1913 Webster]

2. (Math.) The amount of degree of bending of a mathematical curve, or the tendency at any point to depart from a tangent drawn to the curve at that point. [1913 Webster]

{Aberrancy of curvature} (Geom.), the deviation of a curve from a circular form.

{Absolute curvature}. See under {Absolute}.
