湾曲

1. Origins, structure, and basic meaning

• Structure: 湾曲 is read as わんきょく and functions as a noun or with する for a board or structure curving in a smooth arc.
• Basic usage: Use 湿気で板が湾曲する for deformation by a cause and 流れに沿って湾曲する for the path of a curve.

2. Common pitfalls and similar expressions

• Deformation and designed curve
  • Humidity changes the board from its prior shape, while a bridge may be intentionally laid out to follow the river.
• Limited degree
  • 少し and 緩やかに both restrict the curvature, so neither context describes a sharply bent object.
