According to the Merriam-Webster's Collegiate Dictionary, to plagiarize is "to steal and pass off (the ideas or words of another) as one's own." When you use an idea, whether you completely rewrite the idea, paraphrase another, or quote the original, you must give credit to the originator of the idea using citations. Plagiarism at SDSU is governed by the SDSU Student Code 3.f.ii.1.
