Sinuous

Sinuous is an adjective describing something that has many curves or bends; it suggests a winding, serpentine form that curves in and out rather than going straight. The word conveys both motion and grace, often implying flexibility or suppleness. Its etymology traces to the Latin sinuosus, meaning "full of folds or curves," from sinus, "a fold, bend."

In geometry and design, sinuous describes curves and lines that bend repeatedly. It is used to characterize paths, contours, or decorative motifs that shift direction several times, producing a graceful, flowing appearance.

In geography and natural science, sinuous is commonly applied to landforms such as rivers, coastlines, and fault lines that exhibit pronounced meanders or irregular courses. Sinuous waterways, for example, develop through erosion and sediment deposition along their banks.

In biology, the term may describe the shape of organs, roots, or animal tracks that follow a snake-like, winding path. It can also describe movement that is winding rather than direct.

In literature and everyday language, sinuous is used metaphorically to denote complexity or intricacy, as in a sinuous plot or argument, or to evoke elegance and fluidity in style.
