n.
1. The act of curving or the state of being curved.
2. Mathematics
a. The ratio of the change in the angle of a tangent that moves over a given arc to the length of the arc.
b. The limit of this ratio as the length of the arc approaches zero.
c. The reciprocal of the radius of a circle.
3. Medicine A curving or bending, especially an abnormal one: curvature of the spine.

[Middle English, from Latin curvātūra, from curvātus, past participle of curvāre, to bend, from curvus, curved; see sker- in Indo-European roots.]
