How to Write Dialogue: Tags, Beats, Subtext and Punctuation

How to write dialogue, in short: give every line a job (moving the scene on or showing who is speaking), start a new paragraph for each speaker, tag the lines with "said" or an action beat, leave the most important thing unsaid, and put the comma or full stop inside the closing quotation mark. Each of those rules is below, in the words of the writers and editors who set them, with one scene revised from a first draft.

Dialogue is the words characters say aloud, set in quotation marks. Stephen King's test for it in On Writing (2000) is a short one: "the key to writing good dialogue is honesty." He means lines that sound like this person, in this moment, not like the author explaining the plot.

What Are the Rules for Writing Dialogue?

1. One speaker, one paragraph. A new speaker starts a new paragraph.
2. Punctuation goes inside the quotation marks when it ends the spoken line: "Come in," she said.
3. Tag with "said". It is the tag readers stop seeing.
4. No adverbs on the tag. "She said angrily" tells what the line should show.
5. Use an action beat instead of a tag when a gesture can show who is speaking.
6. Every line does a job. Cut greetings, small talk and anything both characters already know.
7. Leave the real subject under the surface. People rarely say what they mean.
8. Go easy on dialect. A few words and the rhythm of a voice carry it.
9. Read it aloud. A line you trip over will trip the reader too.

What Does Dialogue Do in a Story?

Dialogue does two jobs at once. It moves the scene, because characters argue, ask, refuse and decide out loud. And it characterises, because the way someone talks shows who they are faster than any description. In John Steinbeck's Sweet Thursday (1954) Mack, the leader of the boys at the Palace Flophouse, says it plainly: "I want to figure out what he looks like from the way he talks."

A line that does neither job is padding. "Hello." "Hi, how are you?" "Fine, thanks." Real people say it. A novel skips it and starts where the conversation gets interesting.

Dialogue is also where showing happens most naturally. A character who says "I'm fine" while washing the same plate three times has shown the reader something no narrator needs to name, which is the core of show, don't tell.

How Do You Punctuate Dialogue?

Dialogue punctuation follows a few fixed conventions. American publishers use The Chicago Manual of Style; British publishers follow New Hart's Rules, the descendant of Horace Hart's rules for Oxford University Press.

The rest is the same on both sides of the Atlantic:

• A comma, not a full stop, before a tag. "I'm going," he said. A question mark or exclamation mark replaces the comma.
• The tag stays lower case after a question or exclamation, because the sentence continues. Chicago's Q&A: "Because the tag comes in the middle of the sentence, it should be lowercased."
• A tag in the middle of a sentence takes a comma on each side: "If you go," she said, "don't come back."
• A new speaker, a new paragraph. Chicago's Q&A: "It's traditional to start a new paragraph with each new speaker." An action by that same speaker can sit in the same paragraph.
• An interruption takes a dash. For a line cut off mid-word, Chicago's Q&A says: "The conventional punctuation is a dash."
• A speech that runs over several paragraphs opens each paragraph with a quotation mark and closes only the last.

Many guides say British style puts the comma outside the quotation mark. In fictional dialogue it doesn't. Chicago's own blog, CMOS Shop Talk, shows the British rule of placing punctuation "according to the sense" giving way in fiction: 'Punctuation,' I answered, 'is the key to everything.' As it puts it, "British style makes an exception for fictional dialogue."

Should You Use "Said" in Dialogue Tags?

Yes. A dialogue tag (also called a speech tag) is the short phrase that names the speaker: she said, he asked. Elmore Leonard's third rule of writing is the best-known version of the advice:

"Never use a verb other than 'said' to carry dialogue. The line of dialogue belongs to the character; the verb is the writer sticking his nose in. But 'said' is far less intrusive than 'grumbled', 'gasped', 'cautioned', 'lied'."

His fourth rule deals with the adverb: "Never use an adverb to modify the verb 'said' ... he admonished gravely. To use an adverb this way (or almost any way) is a mortal sin."

Stephen King says the same in On Writing: "The best form of dialogue attribution is said, as in he said, she said, Bill said, Monica said." And, more memorably: "while to write adverbs is human, to write he said or she said is divine."

Science fiction workshops gave the habit two names. The Turkey City Lexicon calls a fancy substitute a "Said" Bookism: "An artificial verb used to avoid the word 'said.' 'Said' is one of the few invisible words in the English language and is almost impossible to overuse." An adverb stuck on the tag is a Tom Swifty, after the old Tom Swift adventure books: "'We'd better hurry,' Tom said swiftly."

"Asked" for a question is fine. So is a verb that reports a real change in volume, such as whispered or shouted, used once in a while. What the rule targets is the verb doing the line's job for it.

What Is an Action Beat in Dialogue?

An action beat is a sentence of action next to a line of dialogue that shows who is speaking without a tag:

"He left it to both of us." Ruth filled the kettle.

A beat does three things a tag cannot. It shows the speaker. It gives the reader something to see. And it can carry the subtext: filling a kettle in the middle of an argument is a way of not looking at someone.

The punctuation is the part that trips writers up. A beat is its own sentence, so it is joined to the dialogue with a full stop, not a comma. A Chicago Q&A answer puts it in one line: "People don't point words, they say them." So:

• Wrong: "So up there," Joe pointed at the window.
• Right: "So up there." Joe pointed at the window.
• Right, with a tag: "So up there," Joe said, pointing at the window.

If the beat breaks into the middle of one spoken sentence, the same Chicago answer allows a pair of dashes around it in place of the full stops.

Use beats where they earn their place. A beat on every line is as tiring as a tag on every line. In a two-person exchange where the speakers are clear, many lines need neither.

How Do You Write Subtext in Dialogue?

Subtext is what a line means underneath what it says. Characters who state their feelings outright ("I'm angry because you never supported me") sound like a therapy transcript. Characters who talk about the roof, the dog or the weather while the real argument runs underneath sound like people.

Ernest Hemingway gave the principle its best-known image in Death in the Afternoon (1932):

"If a writer of prose knows enough about what he is writing about he may omit things that he knows and the reader, if the writer is writing truly enough, will have a feeling of those things as strongly as though the writer had stated them. The dignity of movement of an ice-berg is due to only one-eighth of it being above water."

His story "Hills Like White Elephants" (1927) is the classic demonstration. A man and a woman wait for a train and talk about drinks, the hills and "an awfully simple operation". The operation is never named. The man says, "It's not really an operation at all." She says, "Would you please please please please please please please stop talking?" Almost every tag in the story is "said" or "asked".

To write subtext, decide what each character wants from the conversation, then forbid them from saying it.

How Do You Avoid Info-Dumping in Dialogue?

The Turkey City Lexicon names the fault "As You Know, Bob": "A pernicious form of info-dump through dialogue, in which characters tell each other things they already know, for the sake of getting the reader up-to-speed." The same entry records its older names, "Rod and Don dialogue" (attributed to Damon Knight) and "maid and butler dialogue" (attributed to Algis Budrys).

The test is simple: would this character say this to this person? A brother does not tell his sister that their father died last spring. If the reader needs the fact, give it to a character who doesn't know it, put it in an argument where one side wants something from it, or leave it in the narration.

How Do You Write Dialect in Dialogue?

Lightly. Leonard's seventh rule: "Use regional dialect, patois, sparingly. Once you start spelling words in dialogue phonetically and loading the page with apostrophes, you won't be able to stop."

Mark Twain went the other way in Adventures of Huckleberry Finn (1884), and said so in a note at the front: the shadings of its dialects "have not been done in a haphazard fashion, or by guesswork; but painstakingly". That is the standard full phonetic dialect demands. Most novels get further with word choice, word order and rhythm, and a sprinkle of spelling.

A Worked Example

Ruth has come home after her father's funeral to tell her brother Tom she wants to sell the farm. Neither of them says it.

First draft:

"You're selling it, then," Tom snarled angrily.

"As you know, Tom, Dad left the farm to both of us," Ruth retorted.

Three faults: a said-bookism with an adverb on top, a second said-bookism, and an "As you know, Bob" (Tom knows who owns the farm).

Revised:

"You're selling it, then," Tom said.

"He left it to both of us." Ruth filled the kettle.

"The roof needs doing before winter," Tom said.

"Said" carries the first line, and the anger is in the words. The kettle is a beat that shows Ruth not looking at him. Tom's last line is the subtext: he is not talking about the roof. He is telling her he means to stay.

How Do You Write and Revise Dialogue in Deckle?

Deckle is a novel-writing app that keeps each scene as its own document, so a conversation can be drafted fast and revised in place.

1. Plan the conversation. Open the Outliner on the Draft and add the scene with Add › Scene. In its synopsis, write what each character wants from the conversation and what neither will say. That second half is the subtext.
2. Draft it fast. Open the scene and type. Deckle turns straight quotation marks into curly ones as you type, and two hyphens become a dash, the mark Chicago uses for an interrupted line.
3. Keep the first draft. Before you revise, open the Inspector's Versions tab and click + for a new snapshot, so the original exchange is one click away. Saving a version before a rewrite covers snapshots step by step.
4. Hunt the tags. Press Ctrl+Shift+F to open Search Project, then look across the whole book for "replied", "exclaimed", "snarled" or "retorted", with Whole Word on. Click a result to jump to it.
5. Revise tag by tag. Change each one to "said", or cut it and put an action beat beside the line, joined with a full stop.
6. Give each character a voice. A character's Codex entry has a Personality section. Note how they talk there (short sentences, never swears, answers a question with a question) so the voice holds across the book, which also helps when keeping characters consistent.

A text-message exchange or a letter is not dialogue in quotation marks; Deckle has separate block styles for those. A long argument usually forms the scene part of Swain's scene and sequel, with the reaction coming after it.

Common Mistakes

• A comma before an action beat. "Joe pointed" is not a way of speaking. End the line with a full stop, or add "said".
• A tag on every line. In a two-person exchange, the paragraph breaks show who is speaking. Tag when the reader might lose track.
• Said-bookisms and adverbs. "Retorted", "hissed" and "she said coldly" do the line's work. Make the line itself carry it.
• Characters telling each other what they both know. If the line begins "As you know", cut it.
• Saying everything out loud. A character who explains their feelings in full leaves the reader nothing to work out.
• Two speakers in one paragraph. It confuses who said what. Each new speaker starts a new paragraph.
• Mixing quotation mark styles. Pick double (American) or single (British) and keep it through the whole book.

Which Dialogue Rules Are Misquoted?

• "I like a lot of talk in a book." Quote collections often give it as John Steinbeck's own view. In Sweet Thursday it is spoken by a character, Mack, in the book's prologue, where he complains about the way Cannery Row was written. Some write-ups credit Whitey No. 1 instead, because the line follows straight after Whitey's "Go on" in the text, but it is Mack answering him. Leonard quotes it in his second rule and says correctly that "a character in the book" says it.
• "British style puts the comma outside the quotation marks." Only for quoted words and phrases. In fictional dialogue, British books put the comma inside, the same as American ones.
• "Never use any word but said." Leonard's rule is about the verb carrying the line. His own explanation compares "said" with "grumbled", "gasped", "cautioned" and "lied", verbs that comment on the speech. "Asked" for a question is not what he was warning against.
