A dash separates extra information you want to insert into a sentence. Example:

Stephen Sondheim—who lived a privileged, but isolated childhood—is a brilliant observer of human idiosyncrasies.

In Word, a dash is called an em-dash. There are two ways to insert an em-dash:

  • If you have auto-correct turned on, simply type two hyphens and continue typing. Word will automatically convert the hyphens into an em-dash.
  • You can also use the menus: Insert, Symbol, More symbols, Special characters.
