Where you put the comma or full stop is important because it can change the meaning of a sentence. It does not happen often but I have come across writings where improper punctuation is used when writing dialogue, and full stop is used where a comma should be. Below are some examples.
- “I will have a soda with my sandwich.” Said Jane. If you notice the first sentence ends at sandwich. What follows is an incomplete sentence. The correct punctuation should be, “I will have a soda with my sandwich,” said Jane.
- “Wait, I am coming.” Natalie said, as she hurried towards me. In this case the first sentence ends at coming, and what follows is an incomplete sentence. The correct punctuation should be, “Wait, I am coming,” Natalie said, as she hurried towards me.
Always read through what you have written to ensure you have complete sentences. Good luck and happy writing.
