sinuous

The word sinuous traces a direct path from the physical to the abstract. Its core, the Latin sinus, originally denoted a physical fold, curve, or hollow, such as the curve of a garment or a bay in a coastline. This concrete sense evolved in Latin to also describe a winding path. Adopted into English in the 16th century via the French sinueux and the Latin adjective sinuosus ("full of bends"), the word retained its literal meaning of having many curves. Over time, it naturally extended to describe anything with a winding, indirect, or gracefully bending quality, from a river's path to the movements of a dancer or even a complex, twisting narrative.

Structure: sinu (bend, curve) + ous (adjective suffix) - sinu: From Latin sinus, meaning "a bend, fold, curve, hollow." - ous: A suffix forming adjectives, from Latin -osus, meaning "full of, prone to."
