The words "bend" and "curve" are often used interchangeably, but there are subtle differences in their meaning and usage. "Bend" typically refers to a sharp change in direction, often a sudden or angular turn. Think of bending a piece of metal or bending your arm. "Curve," on the other hand, usually describes a gradual, continuous change in direction, often smooth and rounded. Think of the curve of a road or the curve of a smile.

Here's a table summarizing the key differences:

| Feature | Bend | Curve | |----------------|--------------------------|--------------------------| | Degree of angle | Sharp, often angular | Gradual, often rounded | | Change in direction | Sudden, abrupt | Continuous, smooth | | Implied force | Often implies force applied | Usually a natural shape |

Let's look at some example sentences:

• Bend: The road bends sharply to the left. (The road makes a sudden, sharp turn to the left.)
• Curve: The river curves gently through the valley. (The river flows in a smooth, gradual turn through the valley.)
• Bend: I bent the wire to form a hook. (I used force to change the shape of the wire into an angle.)
• Curve: The baseball player hit a curveball. (The ball followed a smooth, curved path.)
• Bend: The tree bent in the strong wind. (The wind forced the tree to make a sharp turn.)
• Curve: The dancer's movements were elegant curves. (The dancer's movements were smooth and graceful.)

Sometimes, the difference is very subtle and the words can be used almost interchangeably. But understanding the nuance helps you use the right word for the situation.
