What to notice in the examples

Effective dash use begins by choosing the correct mark for the job: em dashes for strong breaks or parenthetical emphasis, en dashes mainly for ranges and certain relationships, and other punctuation when the sentence does not need that degree of interruption.

  • Identify whether the job is interruption/emphasis or range/relationship.
  • Use an em dash for a strong sentence-level break or inserted phrase.
  • Use an en dash for number ranges and selected compound relationships according to style.
  • Apply spacing consistently with the publication or style guide.

Turn an example into your own writing

Keep the underlying decision or pattern, then replace the subject, evidence, relationship, constraints, and tone with details that belong to your situation. If your final line still works after swapping only one noun, it may be too close to the example.
