Punctuating quotations correctly

The rule that decides most cases

British and Australian punctuation is logical: a mark goes inside the quotation marks if it was part of what was said, and outside if it belongs to your sentence. That single principle resolves the majority of questions without memorising anything.

So: she described it as 'a fundamental error'. The full stop is yours, ending your sentence, so it sits outside. But: she asked, 'Is this a fundamental error?' The question mark is hers, so it sits inside.

American usage abandons the logic for typographical convention: commas and full stops always go inside, regardless of what they belong to. Colons and semicolons always go outside. Question marks and exclamation marks follow the logical rule.

Choose by your institution's convention, not by what looks familiar from the internet — most of what you read online is American. British and Australian universities expect the logical system.

Single or double quotation marks

British and Australian academic convention uses single marks for a quotation and double marks for a quotation inside it. American convention does the reverse. Both are internally consistent and neither is more correct.

MLA, APA and Chicago are American style guides and specify double marks. OSCOLA, AGLC and most UK and Australian house styles specify single. This is why a document can be simultaneously correct in punctuation and wrong for its style.

Whichever you use, nest consistently: a quotation inside a quotation inside a quotation returns to the outer mark. Three levels of nesting is a sign to paraphrase.

The citation changes where the full stop goes

This is the most common error in referenced writing. When an in-text citation follows a quotation, your sentence ends after the citation, so the full stop goes after the closing bracket.

Correct: The policy was 'a fundamental error' (Ferreira, 2024, p. 12). Incorrect: The policy was 'a fundamental error.' (Ferreira, 2024, p. 12).

The exception is a block quotation, where the citation follows the closing full stop with no further punctuation. That inversion is deliberate and every style specifies it.

In footnote styles, the footnote marker goes after the closing punctuation, and the punctuation follows the ordinary rules.

The comparison, in short

The four systems most students encounter, on the points that differ.

Ellipses: marking what you left out

Three dots mark an omission from within a quotation. Most styles now put them in square brackets — [...] — so the reader can tell your omission from an ellipsis the author wrote themselves.

You do not need an ellipsis at the start or end of a quotation. It is understood that the quoted words came from a longer sentence, and leading ellipses clutter the page.

Never use an ellipsis to change the meaning. Cutting a qualifier so that a hedged claim reads as a confident one is a misquotation, and it is the version of this that gets noticed.

Where you omit a whole sentence or more, some styles use four dots — the sentence's own full stop plus the ellipsis. Chicago specifies this; most others do not.

Square brackets: marking what you added

Anything you insert into a quotation goes in square brackets. That covers a word added for grammatical sense, a clarification of a pronoun, and a change of capitalisation at the start.

So: Ferreira argues that 'it [the policy] failed on its own terms'. The reader knows exactly which words are hers and which are yours.

Changing a capital to a lower case letter, or the reverse, to fit your sentence is permitted in most styles without brackets, though APA and Chicago both prefer brackets around a changed initial capital in formal work.

Never silently change a word. If the quotation will not fit your sentence, rewrite your sentence.

[sic] and when to use it

[sic] means 'thus' and marks an error that is in the original, so a reader does not attribute it to you. Put it immediately after the error, in square brackets, not italicised in current usage.

Use it sparingly. Marking every spelling variant in a historical source makes a page unreadable, and it can read as point-scoring. A note saying 'original spelling retained throughout' handles it once.

Do not use it to signal disagreement. [sic] flags an error of fact or form in the text, not an opinion you dislike, and using it that way is a rhetorical move markers notice.

Introducing a quotation

Three grammatical patterns, and the punctuation follows from which you use. A full sentence introducing a full quotation takes a colon. A quotation woven into your own clause takes no punctuation at all. A reporting verb like 'argues' or 'notes' takes a comma.

The woven version is almost always the strongest, because it forces you to make the quotation do work inside your own sentence rather than sitting beside it.

Never drop a quotation in as a standalone sentence with no introduction. A paragraph where a quotation appears with no attributing words is the pattern markers call a hanging quotation, and it reads as evidence assembled rather than argued.

Check the grammar of the combined sentence by reading it aloud with the quotation marks ignored. If it does not parse, the join is wrong.

Quotation marks for other purposes

Scare quotes — marks around a term you are distancing yourself from — are legitimate once or twice in an essay and corrosive in quantity. Each pair asks the reader to supply a scepticism you have not argued for.

Use quotation marks for a term you are about to define or discuss as a term, and italics for emphasis or for a word used as a word. Different disciplines vary; consistency within the document is what matters.

Do not use quotation marks around a paraphrase. Marks mean these are the exact words, and a near-quotation inside them is a misquotation.

Dashes, hyphens and the marks people confuse

Three horizontal marks do three jobs. The hyphen joins words: well-known, twenty-three. The en dash spans a range: 1939-45, pages 12-18. The em dash sets off a parenthetical clause in a way commas would not.

British and Australian house styles usually set an en dash with spaces either side for a parenthetical break; American styles use a closed-up em dash. Either is acceptable in academic work provided you are consistent, and word processors will autocorrect a double hyphen into one or the other.

In a reference list the en dash is the correct mark for page ranges, and a hyphen is a small error that appears dozens of times if you type your references by hand.

The apostrophe rules cause as much trouble: it marks possession and omission, never a plural. The 1990s takes no apostrophe; the university's policy does; it's means it is and its is possessive, which is the exception that catches everyone.

The final pass

Four searches on a finished draft catch nearly every punctuation error in quotations.

• Search for '." and ".' to find full stops on the wrong side of the closing mark.
• Search for the closing bracket of your citation style and check the full stop follows it.
• Search for three dots and confirm each is bracketed and does not distort the meaning.
• Read every quotation against the original once. Transcription errors are far more common than punctuation errors and much more serious.
