AP Style Extra

Do I Use a Hyphen with Extra?

AP Style holds that you should not use a hyphen with “extra” when it means “outside of” unless the prefix is followed by a word beginning with “a” or a capitalized word. For example, words like the following do not use hyphens,

  • Extralegal
  • Extramarital
  • Extraterrestrial
  • Extraterritorial

A hyphen should follow “extra” when it is part of a compound modifier describing a condition beyond the usual size, extent, or degree. For example, words like the following require hyphens,

  • Extra-base hit
  • Extra-dry drink
  • Extra-large order of fries
  • Extra-bland flavor
