Dashes and hyphens

Dashes and hyphens aren't interchangeable. Follow these guidelines to help you use them the right way, in the right places.

  • Em dashes. Use to set off or emphasize parenthetical phrases.

  • En dashes. Use in ranges of numbers and dates, in negative numbers, and as a minus sign. Use to connect compound modifiers under specific conditions.

  • Hyphens. Use to join words and connect prefixes to stem words. Don't use two hyphens in place of an em dash.
