Definition

Noun: A breakwater is a man-made structure, typically built from stone, concrete, or rock, that projects from the shore into a body of water. Its primary purpose is to protect a harbor, beach, or shoreline by absorbing or deflecting the force of incoming waves, thereby reducing erosion and creating calmer water behind it.

Usage and Examples

• Noun:
  • The city built a new breakwater to protect the marina from winter storms.
  • The old stone breakwater has become a popular spot for fishing.
  • Without the breakwater, the beach would wash away much more quickly.

Advanced Usage

• "to act as a breakwater": Used metaphorically to describe something that serves as a protective barrier against a powerful force.
  • The dense forest acted as a natural breakwater against the strong winds.

Variants and Related Words

• Seawall (n): A solid vertical wall built along the shoreline to protect land from wave action, as opposed to a structure built out into the water.
• Jetty (n): A structure that projects into water, often used for landing or docking boats, which may also provide some wave protection.
