Dialogue is where most manuscripts give themselves away. Not because the words are wrong, but because the punctuation around them wobbles: a comma on the wrong side of an inverted comma, a full stop where a tag needs a comma, a new speaker stranded in the wrong paragraph. Editors notice within a page. Readers feel it without knowing why.
Here are the conventions most British publishers follow, arranged as a checklist you can keep open while you revise.
Pick your quotation marks and stay loyal
British fiction traditionally uses single inverted commas for speech: 'Close the gate,' she said. Double quotation marks are just as acceptable — plenty of UK publishers use them — but choose one and apply it throughout. Mixed usage looks careless, and it's the kind of thing that gets flagged in the first read-through.
The nesting rule runs opposite to American style. In UK English, a quotation inside dialogue takes the other mark:
'He told me, "I'll be late," and left.'
If you're writing in double marks, the inner quotation goes single. Either way, the principle holds: the inner mark is always different from the outer one.
Keep spelling consistent inside dialogue too. 'Colour', 'realise', 'Mum' — unless a character's dialect or background genuinely calls for something else.
Punctuation sits inside the inverted commas
Punctuation that belongs to the spoken words goes inside the quotation marks. That covers commas, full stops, question marks and exclamation marks alike.
'Where are you going?' she asked.
'I'm not sure.' He shrugged.
The exception is punctuation that belongs to the surrounding sentence rather than the speech. Compare these two:
- She asked, 'Are you coming?' — the question belongs to the character, so the question mark sits inside.
- Did she really say 'I'm not coming'? — the question belongs to the narrator, so the question mark stays outside.
That second pattern trips up a lot of writers. The test is simple: ask who is asking. If it's the narrator, the mark goes outside.
Dialogue tags, commas and capitals
A dialogue tag is a phrase that attributes speech: she said, he asked, they whispered. Four patterns cover almost everything you'll write.
- Tag after the speech: comma inside the quotation marks, then lowercase for the tag. 'I'll be there,' she said.
- Tag before the speech: comma after the tag, capital letter for the first spoken word. She said, 'I'll be there.'
- Tag in the middle: comma inside the marks, lowercase tag, then continue lowercase if the sentence runs on. 'Come in,' he said, 'and shut the door.'
- Speech ending in ? or !: keep that mark instead of a comma, and still use lowercase for the tag. 'Are you sure?' he asked.
Never put a full stop before a tag. 'I'll be there.' she said is wrong in every house style I've seen.
Tags versus action beats
Now the distinction that causes the most confusion:
'I'll be there.' She closed the door.
She closed the door is an action beat, not a tag. A character can't 'close the door' a sentence, so it stands alone as its own sentence, with a full stop and a capital letter. The test is whether the verb can describe speech. Muttered can. Smiled can't — you can't smile words, however often the phrase appears in drafts.
Said and asked will carry most of your dialogue, and that's fine. They're nearly invisible. A page of he chortled, she opined, he interjected draws attention to the writing rather than the scene.
Dashes, ellipses and interrupted speech
Use a dash when a character is cut off mid-sentence:
'I was going to—'
'You were going to what?'
Use an ellipsis when speech trails away or a character hesitates:
'I thought you might… never mind.'
The dash is the interruption; the ellipsis is the fade. Keep them doing separate jobs and your dialogue will read more precisely.
On house style: British books often use spaced en dashes for parenthetical asides – like this – while interrupted dialogue tends to take a closed-up em dash—like this. Publishers vary, so check the style guide you're working to and apply it consistently. The same goes for ellipses: spaced or closed up, but always three dots. Not two, not four.
One more small decision to make and then leave alone: after an interrupted line, some publishers close the quotation mark, others leave it open to show the sentence never finished. Follow whichever convention you've chosen, so long as the reader can tell instantly who stopped talking and why.
Paragraph breaks keep speakers straight
One speaker, one paragraph. Every time a new character speaks, start a new line — even if the previous speech was two words long.
When a single speech runs across several paragraphs, open each new paragraph with a quotation mark but place the closing mark only at the very end. That tells the reader the same person is still talking.
And don't put two speakers in one paragraph. The reader loses track, and the fix is usually just pressing Enter.
Small details worth a second look
Names in direct address
A name used to speak to someone is set off with commas: 'Pass the salt, Mira.' Two commas when the name sits mid-sentence: 'Come here, Mira, and look at this.'
Thoughts aren't speech
Most UK fiction sets interior thought in italics, sometimes with a tag such as she thought. Don't wrap thoughts in inverted commas unless the character is genuinely quoting someone.
Quotes inside dialogue
When a character quotes another person, the nested marks reverse: 'He said, "Leave it," and walked out.' If the quotation gets long, move it into its own sentence to avoid a thicket of marks.
A five-minute dialogue proofread
Run this pass after the scene is written, not while you're drafting.
- Read the dialogue aloud. Every place you stumble is a place a reader will stumble.
- Check every tag: comma before it, not a full stop, and lowercase after the comma when the tag follows speech.
- Test each sentence that follows a quotation. Is it a speech verb or an action? Tags take commas; actions take full stops and capitals.
- Confirm your quotation marks are uniform and that nested quotes are reversed.
- Scan your paragraph breaks. Is every new speaker on a new line?
- Search for dashes and ellipses. Interruptions and fades shouldn't be interchangeable.
Punctuation in dialogue is invisible when it's right and irritating when it's wrong. Get the fundamentals consistent and readers will stop noticing the mechanics and start hearing the voices — which is the whole point. If you're submitting to a particular publisher, magazine or competition, read their style sheet before you send anything. House rules beat general convention every time.
