Etymology

The word "rapids" originates from the Latin rapidus, meaning "swift," which itself derives from rapere ("to seize or carry off"). This reflects the fast-moving nature of water in such river sections, as if it were "seizing" objects in its flow. The plural suffix "-s" simply indicates multiple instances of these fast-flowing stretches.

Examples
  1. The canoeists navigated the rapids with skill.

  2. The river’s rapids make it dangerous for swimming.

  3. We heard the roar of the rapids before we saw them.

  4. The tour includes a thrilling ride through the rapids.

  5. Fishermen avoid the rapids because the current is too strong.
