How to punctuate dialogue: tags, beats and quotation marks in fiction

Dialogue on the page runs on a small set of punctuation rules, nearly all settled. What characters should say and how meaning hides under the spoken line are craft questions with their own guide, how to write dialogue. This page is the mechanics: commas and capitals for dialogue tags, tags versus action beats, interruption and trailing-off conventions, multi-paragraph quotations, and American versus British marks.

The basic pattern: comma, capital, new paragraph

When a dialogue tag such as "she said" follows the speech, the spoken sentence ends in a comma inside the closing quotation mark, the tag begins in lower case, and a period closes the sentence. Beth Hill of The Editor's Blog states it exactly: "A comma follows the dialogue and comes before the closing quotation mark. A period ends the sentence." With the tag first, the comma sits outside the marks. The first spoken word is capitalized wherever the speech begins: "Dialogue begins with a capitalized word, no matter where in the sentence it begins." (The Editor's Blog)

The paragraph rule does the rest: "Begin a new paragraph each time the speaker changes" (The Editor's Blog). One speaker per paragraph is how readers track who is talking when tags fall away. New speaker, new paragraph.

Dialogue tags: questions, exclamations and split lines

A spoken question or exclamation keeps its own end mark, which does the work of the comma. Hill again: the question mark "is inside quotation marks. There is no comma. The tag doesn't begin with a cap." The same holds for an exclamation mark.

A tag can also split one spoken sentence; then "Commas go inside the first set of quotation marks and after the dialogue tag (or action)", and the resumed speech stays lower case (The Editor's Blog).

Action beats take periods, not commas

An action beat is not a tag. A tag contains a speech verb (said, asked, whispered); a beat is a separate sentence of physical action beside the speech, attributing the line while keeping the scene visible (see how to write a scene). It is its own sentence, so the quoted line ends in a period, not a comma. Hill's test: with a comma in "I like you," he smiled, "he smiled is turned into a dialogue tag. But people don't smile their speech." Two correct forms:

The first is two sentences; the second keeps the comma pattern. The splice is the most common dialogue punctuation error in manuscripts.

Interrupted speech: the dash convention

When a speaker is cut off mid-word, fiction uses an em dash (the long dash) inside the closing quotation mark. Hill's instruction: "use an em dash before the closing quotation mark". Wikipedia's em dash article records the same use in overlapping speech: the dash "may visually indicate the shift between speakers when they overlap in speech." When the speaker resumes, the new fragment opens with the dash inside its quotation mark. An action can also cut between two pieces of one speech, the pair of dashes sitting between the fragments, outside the marks. (This guide's prose keeps to periods and commas; the dash appears only inside and between quoted speech.)

Trailing off: the ellipsis

The ellipsis marks a voice that runs out rather than being cut: hesitation, a lost thread, a decision not to finish. Hill's example is "He loved you . . ." A dash cuts; an ellipsis fades. Wikipedia's em dash article adds that the ellipsis is the more common choice for unfinished speech, that a dash there "may be ambiguous in expository text", and names aposiopesis: a sentence "stopped short not because of interruption, but because the speaker is too emotional or pensive to continue."

Quotation marks in fiction: American versus British

Two families govern where commas and periods sit, named by Wikipedia's survey of the subject as "American" and "British", or "typesetters' quotation" and "logical quotation". In the American style, "commas and periods are almost always placed inside closing quotation marks", followed by most US publishers and by guides including Chicago and AP. The British style is logical: the marks enclose "only those punctuation marks that appeared in the original quoted material", and other punctuation stays outside, following Fowler's rule that it "must be placed according to the sense." British fiction typically opens dialogue in single marks; American opens in double.

Question marks and exclamation marks go inside or outside by sense in every major form of English, and "only one end mark (?, !, or .) can end a sentence" (Wikipedia). Choose the convention your market expects and hold it across the book (how to format a manuscript).

Multi-paragraph speech and quotes within quotes

A speech that runs past one paragraph keeps opening quotation marks and closes them once: the narrative convention, per Wikipedia, is "to give opening quotation marks to the first and each subsequent paragraph, using closing quotation marks only for the final paragraph", the pattern of the letter in Pride and Prejudice. An opening mark with no closing one means the speaker continues. For a quote inside speech, "the other style is used as inner quotation marks": single inside double in American practice, double inside single in British, and for deeper nesting "the most common way is to simply alternate between the two forms."

Said-bookisms and adverb tags: what the debate is

Replacing "said" with a flourish, or hanging an adverb on it, is a usage debate, not a punctuation rule. Wikipedia's article on dialogue in writing names the flourish: tags "other than said, such as murmured, whimpered or thundered" are known as "said-bookisms" and are "considered to detract from the narrative if over-used". It records Stephen King's position that "said is the best dialogue tag to use", and Cory Doctorow's verdict that they are "writerly laziness" that "weakens the story". Elmore Leonard's rules, reproduced at Go Into The Story, take both halves: "Never use a verb other than 'said' to carry dialogue" and "Never use an adverb to modify the verb 'said'", the latter "a mortal sin". Whether such tags should exist is a voice and subtext question, the territory of how to write dialogue.

Common dialogue punctuation errors

Five errors are worth one dedicated pass:

1. The beat spliced to speech. "I'm leaving," she smiled. Two sentences ("I'm leaving." She smiled.) or a real tag ("I'm leaving," she said, smiling.).
2. The capitalized tag. "Who told you?" She asked. The tag is part of the sentence: "Who told you?" she asked.
3. The missing comma. "I'm leaving." she said. The comma belongs inside the closing mark, the period after the tag.
4. Two speakers, one paragraph. Paragraph-per-speaker is what lets readers track untagged lines.
5. Mixed conventions. American placement in chapter one and British in chapter nine reads as an error in both markets. Pick one convention; a publisher's style sheet wins.

Dialect spellings such as "gonna" are a voice question, not a punctuation one: see eye dialect. When the mechanics are right, the punctuation disappears for the reader.
