Etymology

The word "curve" originates from the Latin curvus, meaning "bent" or "crooked." The morpheme curv preserves this core idea of bending, while the silent -e is a common suffix in English with no semantic function. The word entered Middle English via Old French curve, retaining its original sense of a smooth bend. Over time, it expanded to describe both physical shapes (e.g., a curved road) and abstract concepts (e.g., a learning curve).

Examples
  1. The road ahead has a sharp curve.

  3. The graph shows an upward curve in sales.

  4. He curved the ball around the defender.

  5. The artist emphasized the natural curves of the human body.
