Mechanics of Dialogue: Part 3, Interrupted Dialogue

“Whaddaya mean, interrupted? I’m talkin’ like I al—” Nick jumped as a heavy book flew off the shelf behind him and landed at his feet with a thud.

Forgive me, but it’s Halloween. I had to do something seasonal.

As you can see in that first paragraph, there’s an example of a common type of interrupted dialogue: an intrusion of an action into someone’s speech.

You need to provide some kind of ending punctuation to the speech if the interruption occurs in the middle of a word. Here I’ve used an em dash. There’s not much choice, honestly. I can’t use a period, because the sentence isn’t finished. He’s not questioning, so I can’t use a question mark. It’s not an exclamation, either. Nick is cut off in the middle of the word “always” by what I suspect is poltergeist activity (or perhaps a mischievous cat with back-shelf access and strong muscles). I’ll wager you think you need to use a hyphen, but a case like this one uses an em dash.

When an action intrudes into dialogue this way, an em dash signals “Hey! Watch this!” (I’ll even give you chapter and verse. Chicago Manual of Style 16th edition, 6.86.) It goes where all terminal punctuation for speech goes: inside the closing quotes. There is no space on either side of it per Chicago style. (AP is different, but if you’re writing anything other than news copy, you probably aren’t using AP anyway.)

There could be a need for two em dashes, if the action is in the middle of one person’s speech. Then it looks like this:

“So you don’t believe in poltergeists, Nick? Funny, I’d figured you for one of those”—Phoebe waggled her fingers at him like a cartoon witch casting a spell—“paranormal fanboys.”

Sure, you could put that beat after the speech, but then you lose the effect of her waggling her fingers at him while she’s talking. Consider where the beat needs to go, and write accordingly. Play around with it if you need to. No one will ever know how many iterations you went through (unless you whine about it publicly on social media).

Look at that example. It’s a little different from Nick’s interrupted speech, isn’t it? Phoebe finishes a word before that beat shows up, so there’s no need for an em dash before the closing quotation marks of her first speech. Instead, place an em dash after the closing quotation marks and before the beat, and then place another after the beat and before the next opening quotation marks. Those em dashes punctuate the beat, not the speech. The first word of the second direct speech (paranormal) is not capitalized; there’s no reason for it to be. It’s the next word in her sentence. If that beat hadn’t intruded you wouldn’t capitalize it, so there’s no reason to do so now. The normal rules apply, even when there’s an intruding beat.

What about when someone trails off and doesn’t finish their speech? That’s when you want suspension points or ellipses. Here’s how they work:

Nick glowered at her. “I’m not a fanboy. I’ve never been a fanboy. Just because I have a healthy . . .” His annoyance flagged as his gaze moved, drawn to the flickering lamp in the opposite corner of the room. “Was that lit before? I don’t think that was lit before. I could swear that when we came in . . .” He swallowed hard as the lampshade rotated slowly, clockwise.

As usual, the suspension points go inside the closing quotes. They’re punctuating the speech.

She snickered and walked over to the side table, taking the fringed lower edge of the lampshade between thumb and forefinger to stop it. “You’re a nervous Nelly now, aren’t—OH MY GOD!”

Pheobe had been so sure of herself until . . . something happened. I’ll let you decide what it was. That’s a different kind of interrupted speech, which begins with one tone or subject and suddenly switches to something entirely different. As usual, use an em dash to indicate the change.

Those are the main types of interrupted dialogue, the ones you’re most likely to encounter while reading or to use in your writing. The main things to remember are:

  • Use an em dash if the speaker stops mid-word, in the same way as you’d use a hyphen. Put it inside the closing quotation marks.
  • Use an em dash if the speaker’s able to complete a word, but someone or something stops them before they finish their thought. Put it inside the closing quotation marks.
  • Use an em dash to indicate a sharp change in tone or subject within speech.
  • Use em dashes to punctuate the intruding beat. Place them outside the quotation marks and don’t put spaces on either side of them.
  • Use suspension points to indicate faltering or trailing speech. Put them inside the closing quotation marks. (You can use spaced periods as I did, or you can use the single three-dot glyph your word-processing software provides. If you use the glyph, put a space before and after it.)

Paragraph-Spanning Speech

This doesn’t merit a post of its own, so I’ll include it here. When a single speaker’s speech continues over two or more paragraphs, you don’t put closing quotation marks at the end of each. You put opening quotation marks at the beginning of each, and closing quotes at the end of the entire speech. It looks rather like this:

“What did you expect? We come to the town’s most famous haunted house on Halloween, and you thought what? That nothing would happen?” Pheobe was more than a little irritated. She paced around the coffee table in the middle of the parlor like a panther in a pit trap. “And now that something has happened, you want to—I don’t know, call the cops? I’m really disappointed in you, Nick. I thought you had cojones or something.

            “All right, then. You want to leave, we’ll leave.” She strode across the room and grabbed the door latch. It didn’t budge. Rattling it harder, she glanced back to Nick, who was still staring at the lampshade. “HEY! I said you want to leave, we’ll leave. Help me get this door open.”

Will they get the door open? Will Nick snap out of his fugue? And what about Naomi?

I hope these three posts have helped answer the most common questions about punctuating dialogue. Don’t hesitate to contact me either via email ( or G+ if there’s something I didn’t discuss that you want to know. I’m always happy to explain and educate.
