How to Use Opposites Effectively

Using antonyms like worsen, decline, or regress adds precision in writing and speech. Whether you're reporting news, giving feedback, or analyzing trends, choosing the right word helps express the true state of affairs.

  • Instead of “The project got worse,” try “The project’s performance declined,” which feels more objective.
  • Rather than “They failed to improve,” “They witnessed a decline in output” provides clearer context.
