📚 The Em Dash: Quick Study Guide

  • ✍️ An em dash (—) is longer than an en dash (–) or a hyphen (-).
  • 🛑 It can indicate a sudden interruption in thought.
  • 🔑 It can set off a definition or explanation.
  • ➕ It can replace commas, parentheses, or colons for emphasis.
  • 💻 When an em dash is unavailable, two hyphens (--) are sometimes used as a substitute.
  • 💡 Use em dashes sparingly for maximum impact. Overuse weakens their effect.
  • ✏️ Em dashes can be used to set off appositives, creating a stronger break than commas.
