sinuously

The word 'sinuously' traces its lineage to the Latin noun sinus, which originally denoted a fold, curve, or hollow, such as a bent garment or a bay in the coastline. This root was extended into the adjective sinuosus ("full of bends") via the suffix -osus. Entering English as "sinuous," it described anything with a winding, serpentine form. The adverbial suffix -ly, of Germanic origin, was then appended, creating a word that literally means "in a bending manner." The modern abstract sense of indirectness or devious complexity is a natural metaphorical extension from the physical concept of a non-straight, winding path.
