Just the basic rules for the dash. It is the third one that many people don't always remember.
There are three basic reasons to use a dash:
1. broken sentence structure (This is where the interruption fits.)
2. full sentence dropped into another full sentence
...I want to read to you from -- can you hear me? -- your deposition on May 5.
...I want to read to you from -- this is page 15 -- your deposition on May 5.
3. summary dash
...They insert the needle directing into the brain -- a scary thought.
...We left early that morning -- John and I.
...That is what I was talking about -- that he is not ever on time.
Happy punctuating! Margie
