Plagiarism is using someone else’s words or ideas without giving the original author credit. Using an author’s exact words without quotation marks is one form of plagiarism.

To avoid plagiarism, you can either put the author’s words in quotation marks or paraphrase (restate) the author’s ideas in your own words. (information from noredink.com)

In-text citations connects information you are borrowing from a source to a citation in your bibliography or works cited (from Image Easy Solutions).
