COMM 220 - Public Speaking: Citing Sources

What is Plagiarism?

Plagiarism is the use of someone else’s words or ideas without properly attributing them to their original source. Acknowledging the original source when borrowing ideas or words from others is called “citing sources.” Whether you work with sources or not, you should be aware of the following forms of plagiarism, all of which carry serious consequences in academic and professional settings:

  • Quoting, paraphrasing or summarizing without giving the author credit.
  • Copying word for word whole pieces of writing and passing them off as your own.
  • Mixing your own writing with segments of word for word copying that is unquoted and uncited.  This is known as Mosaic Plagiarism.
  • Having another person, such as a friend or family member, write a paper for which you claim credit.
  • Turning in a paper for an assignment in one class that was originally written for a different class.  It is possible to do this, but you must first obtain the consent of both instructors; otherwise it is considered plagiarism.
