What Is "Sinuous," and Why Do Antonyms Matter?

Before we dig into its opposite, it's important to understand what "sinuous" really means. Knowing this helps us grasp what an antonym should convey.

  • Often used to depict paths, shapes, or forms that are twisting or meandering.

Why do antonyms matter?
Antonyms help us communicate more precisely. If "sinuous" creates imagery of winding and curving, then its antonym should evoke straightness, smoothness, or rigidity depending on context.
