When to Use Single Quotation Marks

by David Harris // January 29  

If you don’t know when to use single quotation marks and treat them like confetti, your editor will circle them like a hawk, and your readers will feel the grit even if they cannot name the rule. Single quotation marks are simple once you commit to one governing idea: follow your style guide for the kind of English you are publishing in, and then apply single quotes only in the few situations where they do real work.

I see this bite authors during production more than during drafting. Drafts can be messy. The problem shows up when you format your manuscript for an editor, a formatter, or Amazon KDP, and your quote marks end up as a blend of US and UK conventions that look careless on the page.

I am going to give you the rules I use when I edit fiction and nonfiction, plus the places where writers get trapped, such as a dialogue within a dialogue, scare quotes, and titles. You will leave with a consistent default for your book and a quick method for fixing your manuscript before it hits copyedit.

The Real Rule: Match Your English Variant And Style Guide

Single quotation marks are not a personal preference. They are standard, and standards depend on the English variant and the style guide in use. For most authors, the decision comes down to US publishing vs UK publishing.

In US English, the default is to use double quotation marks for dialogue and most quoted material, with single quotation marks reserved for quotes inside quotes. In UK English, many publishers default to single quotation marks for dialogue, with double quotation marks reserved for quotes inside quotes. If you mix these, your pages look like you copied and pasted from two different books, because you did.

US Publishing Defaults

If you are publishing primarily in the US market, I recommend you follow Chicago Manual of Style guidance on quotation marks. Chicago is the backbone of many US trade publishing, and even when a house style differs, the differences tend to be small.

Your default in US English looks like this: “I heard him say, ‘Get out now,’ and I believed him.” Double quotes for the main spoken line, single quotes for the quote inside it.

UK Publishing Defaults

If you are publishing primarily in the UK, or you have a UK editor and a UK cover and your readership is known to be there, your default may be single quotes for dialogue.

Your UK default looks like this: ‘I heard him say, “Get out now,” and I believed him.’ Same nesting logic, flipped quote marks.

My Practical Publishing Test

If you are self-publishing wide and your biggest store is Amazon.com, go US style unless you have a strong reason not to. If your book is positioned as UK-facing, set it to UK style early and keep it that way. Consistency matters more than the choice, because readers notice inconsistency as a quality signal.

And if you are working with an editor, ask for the style sheet before you do your final pass. A style sheet is where a good editor records these decisions so nobody has to argue with memory later.

Guide to When to Use Single Quotation Marks: Rules and Tips for Clear Writing

Single Quotation Marks For Quotes Inside Quotes

This is the one use-case almost every author hits, and it is where most quote chaos is born. You have a character quoting someone else, a memoir excerpt quoting an email that quotes a text, or an interview transcription with nested speech.

In US style, the outer layer is double quotes, and the inner layer is single quotes. In UK style, it is reversed. The job is always the same: help the reader see the layers without stopping to decode punctuation.

Fiction Dialogue Examples That Stay Clean

US style:

“Mara said, ‘You owe me,’ and then she walked away.”

UK style:

‘Mara said, “You owe me,” and then she walked away.’

When you have a quote inside a quote inside a quote, do not try to be clever. You alternate marks in the same pattern. If it gets unreadable, that is a craft problem, not a punctuation problem. Rewrite the line so the nesting disappears. In dialogue, you can often convert the inner quote into reported speech.

Nonfiction Examples That Avoid Legalistic Sprawl

If you are quoting a source that already contains a quote, keep the nesting accurate, but tighten everything around it. Example in US style:

“The witness wrote, ‘I heard him say “Don’t touch it” before the alarm sounded.'”

That line is technically fine, but it is ugly. If your book is not a legal transcript, consider breaking the quote into two sentences, or paraphrase the inner line and quote only the phrase you truly need.

Punctuation Placement With Nested Quotes

US style commonly places commas and periods inside closing quotation marks, even when logic would put them outside. Chicago documents that convention clearly in its quotation mark section, and it is the standard most US readers expect.

UK style often follows logical punctuation, which places punctuation outside the closing quote if it is not part of the quoted material. Your publisher or editor will decide this, so do not freelance it halfway through a book.

Single Quotation Marks For Meaning, Not Decoration

Authors reach for single quotes when they want a word to feel special. Sometimes that is correct. Most of the time it reads like you are winking at the reader.

I use single quotation marks for three meaning-based jobs: terms used in a special sense, so-called or disputed usage in limited doses, and glosses in linguistics-style contexts. Even then, I keep the count low on each page.

So-Called Or Skeptical Usage

If you write, the “expert” gave me advice, you are signaling skepticism. Single quotes can do the same job if your style guide prefers them. The craft risk is that constant skeptical quotes create a tone of sarcasm, and sarcasm is exhausting in long form.

If you need skepticism once, use the quotes once. If you need skepticism often, state your stance in a sentence and drop the punctuation. Your reader will believe you more when you do not rely on typographical eye-rolls.

Terms Used As Terms

In nonfiction, you may write: The term ‘read-through’ matters more than many new authors expect. That use can be acceptable, depending on your style guide. Many guides prefer italics for terms introduced as terms, particularly in book-length work.

I usually recommend italics for introduced terms and single quotes for short, one-off mentions where italics would feel heavy. Your copyeditor will have a preference, so pick one method and apply it consistently.

Glosses And Word Meanings

If you are discussing language, you may use single quotes for glosses, like: The Old Norse word meant ‘law-speaker’. This is standard in some academic and reference contexts. If you are writing trade nonfiction, keep it readable and do not over-format your prose into a linguistics paper.

When Single Quotation Marks Create Problems In Manuscripts

The biggest danger with single quotation marks is not that you used them. It is that you used them inconsistently, or you used them to patch a sentence that needs restructuring. These are the spots I check first in a manuscript.

Dialogue Thoughts And Interior Monologue

Some writers put thoughts in single quotation marks, like: ‘I should not be here,’ she thought. That convention exists, but it is far from universal. Many publishers prefer italics for direct thought, and plenty prefer you convert direct thought into free indirect style and drop the tag altogether.

If you use single quotes for thoughts while using double quotes for speech, you create a second quote system your reader must learn. If your book is already complex, do not add a punctuation dialect on top of it. Pick italics or free indirect style and stick with it.

Titles Of Short Works

In US style, titles of articles, short stories, poems, and episodes often appear in quotation marks. On the other hand, full books and films are set in italics. Single quotes rarely belong here in US publishing unless your guide is UK-based or you are following a house style that calls for it.

If you are self-publishing, decide on a single title convention and apply it throughout your manuscript. A clean title treatment is one of those quiet markers of professionalism that readers feel without noticing.

Apostrophes Versus Single Quotes

In modern fonts, the apostrophe and the single quotation mark often share the same glyph. That is convenient until you paste text between programs and your punctuation changes shape, especially if you are moving between Google Docs, Word, Vellum, Atticus, or Scrivener.

Your safest move is to stick to straight quotes while drafting if your production workflow demands it, and then let the formatter or final typesetting stage convert to the correct typographic marks if your book is going to print. Since you asked for straight quotes, keep them consistent and do not let your software auto-swap midstream.

How I Keep Quotation Marks Consistent From Draft To Publication

Consistency is a production habit. If you treat punctuation as a last-minute cleanup, you end up doing fragile global find-and-replace operations at the exact moment you are tired and ready to hit Publish.

I manage quote marks the same way I manage character names and spelling variants. I decide early, I write it down, and I run a targeted pass before I send the manuscript to anyone else.

Pick A Default And Record It In Your Style Sheet

Create a simple style sheet even if you are solo. One page is enough. Write down: US or UK quotation style, how you handle thoughts, whether you use italics for introduced terms, and how you format short-work titles. That sheet saves you from your own future self.

If you use Adazing tools like QuickWrite for drafting bursts, I recommend keeping the style sheet open in a pinned note so you do not drift when writing quickly. Fast drafting is great. Fast drafting without guardrails creates cleanup debt.

Do A Quote Audit Before Copyedit

Before you hand your manuscript to a copyeditor, do a quote audit. Search for single quotation marks and examine each instance. Ask yourself what job the mark is doing. If it is marking a nested quote, keep it. If it is marking emphasis, replace it with a stronger sentence, italics, or nothing.

Also search for patterns that reveal inconsistencies, such as a space before a closing quote, mismatched opening and closing marks, and double single quotes used as a substitute for double quotes. Those errors explode during formatting.

Know What Your Formatter And Retailers Will Do

Some formatting pipelines will convert straight quotes into curly quotes, and some will not. Amazon Kindle rendering can be sensitive to malformed punctuation in the source file, especially when you have nested quotes or HTML conversions in the process. If you have ever seen a Kindle book with missing quotation marks or weird spacing, you have seen what happens when the source text was not clean.

If you are building your own EPUB, test a chapter with heavy dialogue on multiple devices and apps. If you are hiring help, tell your formatter which quotation style you are using and give them your style sheet.

FAQs for When to Use Single Quotation Marks: Rules and Tips for Clear Writing

Should I use single quotation marks for dialogue in my novel?

Use single quotation marks for dialogue if your book follows UK publishing conventions or a specific house style that requires it. If you are publishing primarily for the US market, double quotation marks are the standard for dialogue, and single quotation marks usually appear only for dialogue inside dialogue.

Can I use single quotation marks for emphasis?

You can, but I rarely recommend it in book-length work because it reads like uncertainty or sarcasm. If you want emphasis, rewrite the sentence to carry the emphasis, or use italics sparingly if your style guide allows it. Save quotation marks for actual quotation and the occasional so-called usage where tone truly matters.

What should I do if my manuscript mixes single and double quotation styles?

Pick the style guide that matches your target market, then run a search pass for single quotes and double quotes and fix the patterns systematically. If the mix is heavy, it is often faster to correct it before copyedit, because a copyeditor will charge more when they have to untangle a style decision and clean hundreds of instances.

A Clean Quote Style Reads Like Confidence

Single quotation marks are a tool with a narrow purpose. When you reserve them for nesting or for a deliberate shift in meaning, your pages feel controlled and professional. Decide your US or UK default, record it, and run a quote audit before your manuscript leaves your hands, because fixing punctuation after formatting is one of the least fun ways to spend a publishing week.
