Is Copying Word for Word With a Citation Plagiarism?

Verdict: Depends on the details
The short answer: A citation alone does not make copied wording acceptable. If the passage reproduces a source, show that it is a quotation using the format your assigned style requires, and identify its source. If you want to present a paraphrase instead, rewrite the expression as well as crediting the idea.
How the answer changes
| If | Then |
|---|---|
| You paste a source sentence into your paragraph and put a citation after it, without quotation formatting. | The reference identifies the source but the prose still presents its wording as yours. MIT explicitly includes this problem in improper paraphrasing. |
| The copied passage is visibly marked as a quotation, accurately reproduced, and properly attributed. | The language is represented as borrowed rather than independent. Its relevance, length, and compliance with assignment instructions still need checking. |
| You place a long quotation in a correctly formatted block rather than adding quotation marks. | A recognized block-quotation format can mark the borrowing. Use the actual rules of the assigned style, not a universal line-count rule. |
The reasoning
A reader needs two pieces of information: whose idea is being used and whose words are on the page. A source citation can answer the first while leaving the second misleading. Oxford's quotation guidance and MIT's improper-paraphrasing provision address that gap from different directions. ORI describes the same misunderstanding directly. Synthetic layout example created for this page: imagine an invented project note contains the sentence, 'The model failed at the boundary between the two regions.' Pasting that sentence into your analysis and adding a reference pointer does not visibly identify its language as copied. Marking the exact sentence as a quotation, then explaining what the boundary failure means for your own argument, makes the division of voices explicit. Alternatively, describe the relevant result independently and attribute the information. Neither route requires inventing a differently worded claim. The project note and sentence here are fictional teaching material, not a bibliographic reference or a real model test. For an actual paper, supply an engine-generated citation from the real source metadata and consult the required style for locators and block formatting. Do not treat a reference list, quotation marks, and a meaningful explanation as interchangeable tasks.

Decide for your own case
Answer these questions about your situation. Each no or unsure is a reason to ask your instructor before you submit.
- Would a reader immediately see where the author's exact language starts and ends?
- Does the quotation reproduce the actual source rather than a remembered version?
- Is the citation attached to the quoted passage rather than only listed at the back?
- Have you checked block-quotation requirements instead of assuming quotation marks are always the right form?
How to fix it
- Locate every verbatim sentence, including language pasted into captions, notes, or a draft outline.
- Choose deliberately between an exact quotation and an independent paraphrase instead of leaving a hybrid sentence.
- For quotation, check every word against the source and apply the assigned style's quotation and locator requirements.
- Read the surrounding paragraph to make sure your own analysis is distinct from the quoted evidence.
Frequently asked questions
No. Listing a work does not by itself label the words taken from it. The reader must be able to identify both the source of the passage and the fact that the language is quoted rather than your own expression.
A style's block format can identify a quotation without enclosing it in ordinary quotation marks. The important point here is visible, correct quotation treatment plus attribution. Check your actual style guide for its length and layout requirements.
Not covertly. Purdue's distinction requires a quotation to reproduce the source accurately. If your goal is independent wording, write and attribute a paraphrase; do not present an edited sentence as either an exact quote or wholly original language.
Every statement links to its source. A verdict reads published rules and does not decide your case. Found a mistake? Report a correction.
