How do you punctuate dialogue?

Good dialogue punctuation keeps your prose clean, your characters’ voices clear, and your pacing intentional. Once you know the standard rules, you can bend them in service to voice, rhythm, and emotional impact. But consistency is key—your reader should never be distracted by how the dialogue looks on the page.

The following information and rules apply to American English and follow the Chicago Manual of Style (CMOS).

They also mostly apply to British English and follow the New Hart’s Rules (NHR), Oxford Style Guide. However, British English uses single quotation marks for primary dialogue, with double quotation marks for internal quotes—the reverse of CMOS. Additionally, when quoted speech is broken off and then resumed after words such as he said, the punctuation sits outside quotation marks; if the punctuation is spoken, it stays inside:

·      ‘Go home’, he said, ‘to your father.’

·      ‘Yes,’ he said, ‘we will. It’s a good idea.’

Basic dialogue punctuation

Before diving into the special cases, here’s a quick refresher:

·      Dialogue is enclosed in double quotation marks (“ ”).

·      Commas and periods go inside the quotation marks.

·      A dialogue tag (she said, he asked) is separated with a comma.

·      Action beats stand on their own as sentences unless grammatically joined.

Examples:

·       “We should leave,” she said.

·       She opened the door. “We should leave.”

·       “Should we leave?” he asked.

Action beats or dialogue tags

Often action beats are mistakenly used as dialogue tags. We have a handy resource on this. Email us at info@katsliteraryservices.com for your free copy. You don’t need to be one of our clients to request this.

Example:

·      “Stop,” she breathed. ← Technically, you can’t breathe words; breathe is an action beat, but there are a few ways you could rephrase this to make it grammatically correct.

In practice:

·      “Stop,” she breathed out. ← Generally, “breathed out” is only used for one word.

·      “Stop,” she said on an exhale.

·      “Stop.” Her words were quiet and breathy.

Similarly, you can’t laugh, gasp, groan, pant, sigh, or smirk words. There can be a little creative license with groaning and moaning. We tend to leave single words as groans or moans, but if it’s a complete sentence or a few words, we’ll rework the sentence.

Special cases for punctuating dialogue

1. Stuttering or hesitation

CMOS and NHR recommend using a hyphen to indicate stuttering or repeated sounds—not ellipses.

Examples:

·       “W-w-wait!”

·       “It’s n-not your fault.”

Hyphens show broken speech; ellipses indicate pauses, hesitation, or trailing off (see below).

2. Trailing off (speech fading out)

Use an ellipsis (…) when a character’s sentence tapers off.

Examples:

·       “I thought I saw something in her eyes. Well, never mind…”

·       “If only you knew…”

3. Abrupt endings (interrupted speech)

Use an em dash—no spaces—to show an interruption.

Examples:

·       “If you’d just listen for one—”

·        “Don’t touch that—”

·        “I swear if you walk out that door—”

If another character interrupts, follow with their speaking line:

·       “I just think we should—”

“Enough. We’re done.”

The em dash indicates cut-off, not hesitation.

4. Offsetting action beats

An action beat is a short piece of action that replaces or supports a dialogue tag.

Option A: Dialogue + action, separated by a period

·       “Try again.” She crossed her arms.

Option B: Dialogue + dialogue tag, followed by an action

·       “Try again,” she said, then crossed her arms.

Option C: Dialogue + action as part of the sentence

·       Crossing her arms, “Try again,” is all she offers.

The rule:

If the beat is a complete action, it cannot take the place of a dialogue tag.

Incorrect:

·       “Try again,” she crossed her arms. ← an action cannot act as a dialogue tag.

Correct:

·       “Try again.” She crossed her arms.

5. Action beats within dialogue

If an action beat is written in the middle of a line of dialogue, the action beat is offset with closed em dashes outside the quotation marks and no comma inside the quotation marks at the end of the first part of speech.

Example:

·      “What do you think about this”—she holds up a dark-red dress—“for the party tonight?”

6. Quotes within quotes

According to CMOS, you use:

·       Double quotation marks for main dialogue.

·       Single quotation marks for quotations inside dialogue.

The opposite is true for NHR. Single quotation marks for main dialogue, with double quotation marks for quotations inside dialogue.

Examples (CMOS):

·       “Did he really say, ‘It’s over’ before he left?”

·       “I heard her whisper, ‘Don’t move.’”

·       “She told me, ‘The code word is “sparrow,”’ but I don’t trust her.” (If another quotation is nested within the second quotation, revert back to the original mark, i.e., double–single–double.)

Note that punctuation still follows standard placement rules: Periods and commas go inside both sets of quotation marks.

7. One or two words that don’t require quotation marks

Certain common expressions appear like dialogue but don’t need quotation marks unless directly spoken.

Examples that usually do not require quotes: 

·      thank you, hello, goodbye, yes, no, okay, stop, sorry.

These are treated as ordinary words unless you are quoting exact speech.

No quotation marks needed:

·      She whispered hello as she entered.

·      His letter ended with a simple thank you.

Quotes needed if it’s actual dialogue:

·       “Hello,” she whispered.

·       “Thank you,” he said.
