You can write the most balanced dialogue in the world, but if your punctuation is messy, your story will look amateurish. Punctuation tells the reader exactly how a sentence sounds, where the pauses happen, and who is speaking.
When you master these technical rules, your text becomes much cleaner and easier to read.
The Standard Speech Tag Rule
When a dialogue tag follows a spoken sentence, use a comma inside the quotation marks, not a period. The tag that follows should start with a lowercase letter, even if it is a proper noun.
Incorrect: "I am leaving tomorrow." she said.
Correct: "I am leaving tomorrow," she said.
If the tag comes before the spoken words, place a comma right before the opening quotation mark.
Correct: She said, "I am leaving tomorrow."
Question Marks and Exclamations
Question marks and exclamation points follow different rules than commas. They stay inside the quotation marks, but you still keep the following tag lowercase because it is part of the same sentence structure.
Incorrect: "Where are you going?" She asked.
Correct: "Where are you going?" she asked.
Do not stack exclamation points to show a character is yelling. One punctuation mark is plenty if your dialogue choice is strong enough.
Formatting Action Beats
Action beats are separate sentences showing physical movement. Because they are independent actions rather than tags about speaking, use a period inside the quotes. The sentence that follows always starts with a capital letter.
Incorrect: "I am completely finished," he picked up his coat.
Correct: "I am completely finished." He picked up his coat.
Using these rules prevents long, run-on sentences that confuse your reader. Clean punctuation acts like invisible scaffolding, letting your actual narrative shine.
