The state of being curved or the degree to which something is curved. In Japanese, this is expressed with nouns like 曲率 (curvature in mathematical/scientific contexts) and 湾曲 (a curved shape), or with adjectives like 曲がっている (is curved/bent).
Describing something that is curved, bent, or not straight in a physical sense.
Refers to a curved shape or the state of being curved, often used for natural or gradual curves like a river bend or a curved spine.

This design uses beautiful curvature.
Refers to a warp or curvature, often in a specific direction, like the curve of a sword blade or a warped board.
The curvature of the sword is beautiful.
The precise measure of how much a curve deviates from a straight line, used in math, physics, or engineering.
The standard term for 'curvature' in mathematics and physics, e.g., curvature of a curve, surface, or space.
Please calculate the curvature of this surface.
Sometimes used for 'curvature' in medical or biological contexts, like curvature of the spine, but 曲率 is more common in pure math.

Referring to abnormal curvature of the spine, such as scoliosis or kyphosis.
Medical term for scoliosis, a lateral curvature of the spine.
I was diagnosed with curvature of the spine (scoliosis).
General term for spinal curvature, can refer to any abnormal curve.
湾曲 (わんきょく) describes the shape or state of being curved, often in a physical, visible sense. 曲率 (きょくりつ) is the mathematical measure of curvature. Use 湾曲 for everyday descriptions and 曲率 for technical contexts.
カーブ (from English 'curve') is common for road curves or sports trajectories, but it's not used for the abstract concept of curvature. Stick to 湾曲 or 曲率.
Spinal curvature can progress with age.
