Plagiarism involves using someone else's work without giving them proper credit. It can include copying word-for-word or paraphrasing without citation. The consequences of plagiarism range from failing an assignment to expulsion. To avoid plagiarism, one should not copy and paste from sources, but rather summarize in their own words and always cite sources both in-text and in a works cited page using the author's last name or article title if no author is given.
