idiom

A double-edged sword is something that has both good and bad effects. It can help in one way but also cause problems in another. It is often used for situations, choices, or tools.

  • Social media is a double-edged sword.
  • Working from home is a double-edged sword.

Adinary Nuance

A double-edged sword is not the same as a simple problem or benefit. It means the same thing brings both advantages and disadvantages. Writers often use it when one choice looks useful, but also creates risk. It is stronger and more vivid than saying something is just 'mixed' or 'complicated.'
