Dialogue is spoken communication between characters. The purpose of a tag line is to let your reader know which character is speaking.
Most commonly used dialogue tags:
As a reader, we hardly notice the tag lines. “He/she said” is boring, and our eyes are used to reading said. We want to know what’s between the quotation marks.
Seriously, can a person “screech” or “Sigh” or “acknowledge” words? Can you “laugh” a sentence? Instead use descriptive words to create motion or response in your characters. Over use of anything besides “said” can be annoying. Think of how you can use narrative in place of tag lines.
One of the best resources for an explanation of dialogue is the book WRITING REALISTIC DIALOGUE AND FLASH FICTION by Harvey Stanbrough. I highly recommend this book as an addition to your writing reference library.
Here’s an example from Mr. Stanbrough’s book:
She approached him cautiously. “Come on now, Baby,” she cooed. “You don’t want that knife. What are you going to do with that?”
He swung the knife in a wild arc. “I just can’t stand it anymore!” he exclaimed. “I’ve had it?”
If you read the same passage above out loud omitting the tag lines, it reads the same. In fact, we might even say that the tag lines of cooed and exclaimed are somewhat annoying. You could add a he said or she said if you want, but the action and narrative helps us know who is talking. The imagery is still the same no matter what tag lines you use.
Happy writing and thanks for following WordsmithSix!
