To quote sources correctly, copy the author’s exact words inside quotation marks, introduce them with a signal phrase, and follow them immediately with an in-text citation that includes the page number — for example, Smith (2020, p. 14) argues that “originality is a habit, not an accident.” This guide explains when to quote rather than paraphrase, how to format short and long (block) quotes, the punctuation rules for ellipses, [sic] and square-bracket edits, and how to integrate quotations smoothly in both APA and Harvard styles — with worked examples and a comparison table.
When to quote vs when to paraphrase
Quoting and paraphrasing are both legitimate ways to use a source, but they answer different needs. A direct quotation reproduces an author’s exact words; a paraphrase restates their idea in your own words and sentence structure. Most of your academic writing should be paraphrase, because paraphrasing shows you have understood and synthesised the material rather than simply copied it. Reserve direct quotation for the moments where the original wording itself matters.
Quote a source when:
- The exact phrasing is precise, memorable or technically important, and rewording it would lose meaning (for example a legal definition or a famous turn of phrase).
- You are analysing the language itself — in a literature, history or discourse essay where the wording is your evidence.
- You want to present an authoritative voice verbatim, such as a key finding stated in the author’s own words.
- Restating the point would risk distorting a contested or carefully qualified claim.
Lean on a paraphrase instead when you only need the idea, the data point or the argument, not the specific wording. As a rough proportion, most markers expect the great majority of an essay to be in your own words, with direct quotation making up only a small fraction of the whole. If you are unsure how to restate a passage faithfully without slipping back into the original phrasing, our guide on how to paraphrase academic sources walks through the technique step by step. A simple rule of thumb: if you cannot explain why you are quoting rather than paraphrasing, you should probably paraphrase. Remember that both quoting and paraphrasing require a citation — the difference between them is never a reason to skip attribution. For the wider question of which material needs a citation at all, see our explainer on what to cite and what not to cite.
Short (in-line) quotes vs long (block) quotes
The length of a quotation decides how you format it. Short quotations run inside your own sentence, wrapped in quotation marks. Long quotations are set off from the main text as a free-standing, indented block with no quotation marks — a format known as a block quote.
The word threshold depends on your referencing style. In APA (7th edition), a quotation of fewer than 40 words is run in-line, and a quotation of 40 words or more is formatted as a block quote. In MLA, the cut-off is prose longer than four lines (or poetry longer than three lines). Many Harvard guides use a similar threshold of roughly 40 words or three to four lines, but Harvard is a family of styles rather than a single rulebook, so always check the exact specification your department issues.
A block quote is indented as a whole, usually double-spaced, and the citation sits after the closing full stop. Because the indentation itself signals the quotation, you do not add quotation marks around a block quote. For the precise indentation, spacing and citation placement — which differ slightly between styles — follow our dedicated guide on how to block quote. Use block quotes sparingly: a page broken up by long indented blocks reads as padding and signals to your marker that you are leaning on sources instead of building your own argument.
Punctuation and formatting rules
Once you have chosen a quotation, you must reproduce it accurately — and signal clearly any change you make. A handful of conventions cover almost every situation.
Quotation marks
UK academic writing typically uses double quotation marks for a quotation, and single marks for a quotation-within-a-quotation (some style guides reverse this, so check yours and be consistent throughout). Place the quotation marks tightly around the borrowed words only — never around your own framing.
Ellipses for omissions
When you leave words out of the middle of a quotation, mark the gap with an ellipsis — three spaced dots (. . .) or the ellipsis character (…). This tells the reader you have shortened the original without changing its meaning. Do not use an ellipsis at the very start or end of a quotation simply because you began part-way through a sentence; readers assume a quotation is an extract.
Square brackets for your own edits
Use square brackets to insert a word, change a capital letter, or clarify a pronoun so the quotation fits your sentence grammatically. For instance, if the original reads “they refused the request” you might write “[The committee] refused the request” to make the subject explicit. The brackets make it transparent that the bracketed words are yours, not the author’s.
[sic] for errors in the original
If the source contains a spelling or grammatical error, reproduce it exactly and add [sic] immediately after it. This Latin tag (meaning “thus”) shows the mistake was in the original and is not a typo of your own. Use it sparingly and never to mock a source — its purpose is accuracy, not point-scoring.
APA, integrated: Carter (2021) reports that “students who receive timely, specific feedback on early drafts produce stronger final essays” (p. 87).
Harvard, integrated: As Carter (2021, p. 87) observes, “students who receive timely, specific feedback… produce stronger final essays”.
Notice the ellipsis (…) marking the words removed for concision, the quotation marks around the borrowed wording, the signal phrase that names the author, and the page number. Remove any one of those four elements and the quotation is no longer correctly formatted — or, worse, no longer honest.
Integrating quotes smoothly with signal phrases
A quotation should never be dropped into your paragraph cold. A so-called “dropped quote” — a full sentence of quotation with no lead-in — jolts the reader and leaves the borrowed words doing your analysis for you. The fix is a signal phrase: a few words that name the source and frame what follows.
Signal phrases usually name the author and choose a reporting verb that conveys your stance toward the claim. The verb is not neutral — argues, claims, demonstrates, concedes and suggests each tell the reader something different about how much weight you give the point. Useful examples include:
- Smith (2020) argues that …
- As Patel (2019) demonstrates, …
- According to the report, …
- Lee (2022) concedes that …
After the quotation, add a sentence of your own that explains why it matters — the “quote sandwich” of introduce, quote, then analyse. A quotation that is introduced but never explained is only half-integrated. The figure above shows the three parts working together: the signal phrase, the quotation in marks, and the citation.
Always cite a quote — with a page number
Every direct quotation needs an in-text citation, and that citation must include a page number (or paragraph number for unpaginated web sources). The page number is what lets a reader locate the exact words in the original; omitting it from a direct quote is an incomplete citation even when the author and year are present.
Quoting without any attribution is plagiarism — it presents another writer’s exact words as your own. So is “patchwriting”: copying a passage and swapping a few words while keeping the original structure, with or without a citation. If you are unsure where the line falls, our comprehensive guide to plagiarism sets out the main types, and our practical roundup of tips to avoid plagiarism covers the habits that keep your work clean. You can also confirm a citation is complete by checking it against your referencing style guide before you submit.
“A direct quotation reproduces words verbatim from another work… When quoting directly, always provide the author, year, and specific page number of the quotation in the in-text citation.” — American Psychological Association, Publication Manual (7th ed.), Section 8.25
Over-quoting inflates your similarity score
Even perfectly cited quotations count as matched text in a similarity report. A plagiarism or similarity checker compares your writing against a large database and flags overlapping strings — and a correctly quoted, correctly cited passage still overlaps word for word with its source. So an essay stitched together from long quotations can return a high similarity percentage that is technically “clean” but academically weak, because it shows little original thinking. Markers and integrity software both notice.
It is worth being clear about what a similarity percentage does and does not mean. A higher figure is not automatically “cheating”, and a lower figure is not automatically good work; the number simply reflects how much of your text matches existing sources. Most institutions read the report alongside the writing, looking at where the matches fall — a string of quotations and reference-list entries is very different from an unattributed paragraph lifted from another essay. The goal is therefore never to chase a particular number, but to ensure every match is either properly quoted and cited or, better still, replaced with your own analysis.
The remedy is not to hide quotations but to use fewer of them: paraphrase where the wording does not matter, trim quotations to the essential phrase, and make sure your own analysis surrounds every borrowed line. Before you submit, it helps to see how much of your draft is quoted and whether every quote carries a citation. Run it through our free plagiarism checker — a basic web check for documents up to about 3,000 words — to spot heavy quoting and uncited passages early. For a full, Turnitin-level originality report that also includes AI-writing detection, our paid plagiarism report gives a detailed breakdown, and our separate AI detector checks for AI-generated text. If a check surfaces passages you need to rework, our guide on how to remove plagiarism explains how to fix them legitimately — by paraphrasing and citing properly, never by trying to disguise the match.

Worked examples: APA and Harvard
The mechanics of a quotation are the same in every style — exact words, quotation marks, signal phrase, citation with page number — but the citation format differs. The table below compares how APA (7th edition) and Harvard handle the same quotation, and the example box above shows a single quote integrated correctly in each style. For broader help choosing and applying a style, see our overview of how to cite sources and our dedicated Harvard referencing guide.
| Feature | APA (7th edition) | Harvard |
|---|---|---|
| In-text format | (Author, Year, p. X) | (Author, Year, p. X) |
| Page abbreviation | p. 14 (one page) / pp. 14–15 (range) | p. 14 (one page) / pp. 14–15 (range) |
| Short-quote example | Smith (2020) found that “feedback drives improvement” (p. 14). | Smith (2020, p. 14) found that “feedback drives improvement”. |
| Block-quote threshold | 40 words or more | Roughly 40 words / 3–4 lines (check your guide) |
| Block-quote citation | After the closing full stop, no quotation marks | After the closing full stop, no quotation marks |
| Reference list name | References | Reference list |
A few details are worth highlighting. In both styles the page number is mandatory for a direct quote. APA places the author and year together at the first mention and the page number in the parentheses after the quote; Harvard often bundles author, year and page into a single citation. Block quotes in both styles drop the quotation marks and place the citation after the final full stop. When the same author appears more than once, you cite the page each time you quote, even if the year and author are unchanged.
Common quoting mistakes to avoid
Most quoting errors fall into a short list. Watch for these:
- Quoting without a page number — an incomplete citation for any direct quote.
- Dropping a quotation in with no signal phrase or no follow-up analysis.
- Altering the wording silently instead of marking edits with square brackets or an ellipsis.
- Over-quoting — letting borrowed text crowd out your own argument and inflate your similarity score.
- Mixing quotation-mark styles or referencing formats within one document.
- Misrepresenting a source by quoting it out of context.
Get the fundamentals right — quote only when the wording matters, reproduce it accurately, frame it with a signal phrase, and cite it with a page number — and your quotations will strengthen your argument while keeping your work honest and original.
