If you use other people's ideas without giving them credit by citing their work, you are committing plagiarism. Plagiarism is using someone else's ideas or words and presenting them as your own, whether intentionally or unintentionally.
To avoid plagiarism, always provide a proper citation when you quote or paraphrase the idea of another person in your research paper, speech, slide presentation, etc. What constitutes a proper citation will depend on which citation style you're using. You'll learn more about citation styles later in this module.
