The word "curvative" refers to something that bends or follows a curved shape. Its antonyms, on the other hand, are words that describe straightness or the absence of curves. Some of the antonyms for "curvative" are angular, straight, linear, flat, and uncurved. These words depict shapes that do not have any curves, bends, or twists. Unlike curvative, which can be associated with feminine forms and organic shapes, its antonyms are often used to describe masculine, geometric, or industrial designs. While curvative suggests movement, fluidity, and softness, its antonyms evoke rigidity, stability, and stiffness.
