• A dash is sometimes used instead of a colon or a semi-colon.

EXAMPLE: "Quick! Go now – the police are coming for you!"

 

  • When dashes are used in a sentence, commas are not used to separate interrupting phrases.

EXAMPLE: She looked at the dresses – a few of them – deciding on the one she should buy.
NOT: She looked at the dresses, – a few of them, – deciding on the one she should buy.
