Dash vs Ellipsis

In the last grammar post, I talked about the different dashes – or at least the hyphen, en dash, and em dash. You may have noticed that some uses for the dash overlap with the ellipsis. Here is a brief guide that can help you learn when to use the ellipsis or the dash.

Ellipsis ( … )

  1. Ellipsis are often used to denote a thought or sentence that is incomplete or trails off.
    • “Don’t go in there, it’s…” he paused to gather his thoughts, “…weird.”
  2. Use ellipsis when quotes are being shortened or when material is being omitted from the passage.
    • The absurdity of the situation makes me ponder Hamlet’s query “whether ‘tis nobler in the mind to suffer . . . outrageous fortune.”
  1. Use a 4-period ellipsis (also called a closed ellipsis) when ending with a partial quote.
    • Original sentence: I have a weathered copy of that photograph in my own personal collection.
    • Partial quotation using a closed ellipsis: I have a weathered copy of that photograph ....

Dash ( – )

  1. Dashes are often used in dialogue writing to denote that someone has been cut off.
    • “Don’t go in there it’s–” The door slammed in his face before he could warn them.
  2. As mentioned in the last post, dashes are used to interrupt the sentence. They can be used to start lists that have commas in them, used to illustrate, restate or summarize a sentence, or even change tone.
    • Three people in my group–Tom, Rodger, and Sally–refused to participate in critiques.
    • One person of the group will only wear blue–my mother.
    • Tom did not wish to participate because his feelings for Sally–he is madly in love with her–will never change.
  3. Dashes are used to set off appositives that contain commas. Appositives are noun or noun phrase that immediately follows a noun or pronoun.
    • Learning the mechanics–the complex, detailed structural components–of the English language is very difficult because the rules are often so inconsistent

Writing dialogue

A Simple Rule for Writing Dialogue: Use the ellipsis for when a sentence trails off and use the dash when a sentence gets cut off.

Ellipsis and dashes add great variety to a piece, but like most grammar, needs to be used properly. Ellipsis and dashes are best used sparingly.
