The grammatical pause is the most obvious and easy to use pause. Even so, I have to remind you that you need to give a reasonable pause for a full stop and a new paragraph. In general, you indicate a change of idea with your pause. If you don’t pause, it’s really confusing for your listener.
Grammatical Pause Example
“Hurry up, boy!”| Shouted Uncle Vernon from the kitchen. |
“What are you doing,| checking for letter-bombs?”| He chuckled at his own joke.|
Harry went back to the kitchen,| still staring at his letter. |He handed Uncle Vernon the bill and the postcard, |sat down and slowly began to open the yellow envelope.|
