Etymology
the word curvature is a direct inheritance from late latin 'curvatura', which itself is formed from the latin verb 'curvare' meaning 'to bend'. the root 'curv-' can be traced back to the proto-indo-european root 'sker-', meaning 'to turn, to bend', a prolific root also giving rise to words like 'circle', 'crown', and 'ring'. the suffix '-atura' was used in latin to form nouns expressing the action or result of a verb, a function preserved in the english '-ature'. thus, curvature logically denotes the state or measurable result of the action of bending, evolving from a physical description to a precise mathematical concept.
Analysis
Structure: curv (curve) + ature (noun suffix denoting state or result)
