抄襲指嘅係將人哋貢獻嘅作品，喺冇提供足夠嘅作者權益資訊之下，將佢嘅語言以及思想變成係自己嘅作品。劍橋大學將抄襲定義為：「submitting as one's own work, irrespective of intent to deceive, that which derives in part or in its entirety from the work of others without due acknowledgement.」
所有來源會以行內引用進行標註，一般會以腳註嘅方式來進行引用（請睇引用來源）。除咗行內引用，引用原文或者略略改寫過嘅原文都要同時喺嗰句加埋來源（例如：「約翰·史密夫寫到，呢座建築物睇起嚟好壯觀」，或者「根據史密夫（2012年）嘅文獻......」）。The Manual of Style requires in-text attribution when quoting a full sentence or more. Naming the author in the text allows the reader to see that it relies heavily on someone else's ideas, without having to search in the footnote. You can avoid inadvertent plagiarism by remembering these rules of thumb:
抄襲同版權侵害係兩樣嘢。 Copyright infringement occurs when content is used in a way that violates a copyright holder's exclusive right. Giving credit does not mean the infringement has not occurred, so be careful not to quote so much of a non-free source that you violate the non-free content guideline. Similarly, even though there is no copyright issue, public-domain content is plagiarized if used without acknowledging the source. 想揾點樣避免喺維基百科侵權嘅建議，睇侵犯版權..
- "What Constitutes Plagiarism?", Harvard Guide to Using Sources, Harvard University: "In academic writing, it is considered plagiarism to draw any idea or any language from someone else without adequately crediting that source in your paper. It doesn't matter whether the source is a published author, another student, a Web site without clear authorship, a Web site that sells academic papers, or any other person: Taking credit for anyone else's work is stealing, and it is unacceptable in all academic situations, whether you do it intentionally or by accident." The university offers examples of different kinds of plagiarism, including verbatim plagiarism, mosaic plagiarism, inadequate paraphrase, uncited paraphrase, uncited quotation.

There may be exceptions when using extensive content from free or copy-left sources, so long as proper attribution is provided in footnote or in the references section at the bottom of the page.
- See Wikipedia:Manual of Style#Attribution: "The author of a quote of a full sentence or more should be named; this is done in the main text and not in a footnote. However, attribution is unnecessary with quotations that are clearly from the person discussed in the article or section. When preceding a quotation with its attribution, avoid characterizing it in a biased manner."
