Punctuate dialogue correctly by learning the core rules: a dialogue tag attaches with a comma ("“Hello,” she said"), while an action beat is a separate sentence with a period ("“Hello.” She waved"). In US style, commas and periods go inside the quotation marks. Start a new paragraph for each new speaker. Question marks and exclamation points replace the comma before a tag ("“Why?” he asked"). These rules are specific but learnable, and getting them right is essential to professional-looking prose.
Chapter i·Why it matters
Incorrect dialogue punctuation is one of the clearest markers of an amateur manuscript — agents, editors, and readers notice immediately, and it undermines otherwise good writing. Because the rules are specific (and the tag-versus-action-beat distinction trips up many writers), they must be learned rather than guessed. Understanding correct dialogue punctuation is a basic but essential craft skill; errors here can sink a submission before the story is even judged.
Chapter ii·What to include
- Comma for a dialogue tag.
- Period for an action beat.
- Punctuation inside the quotation marks (US).
- A new paragraph per speaker.
- Question/exclamation marks replacing the comma.
- The rules learned, not guessed.
Chapter iii·Example
A writer corrects her dialogue punctuation: "“I’m leaving,” she said" (comma for the tag) versus "“I’m leaving.” She grabbed her coat" (period for the action beat). She moves punctuation inside the quotes and starts a new paragraph for each speaker. The corrected punctuation makes her dialogue look professional, where the errors had signaled an amateur draft.
