    • "The bridge was showing signs of decay." (verb – showing the process)

Tips for Using "Decay" Correctly:

  • Context is crucial: Pay attention to what is doing the decaying and what is being decayed.
  • Be specific: Instead of just saying something is "decaying," try to describe how it's decaying (e.g., "rotting," "crumbling," "diminishing").
