"Plagiarism is using someone else’s ideas or words without giving them proper credit. Plagiarism can range from unintentional (forgetting to include a source in a bibliography) to intentional (buying a paper online, using another writer’s ideas as your own to make your work sound smarter). Beginning writers and expert writers alike can all plagiarize. Understand that plagiarism is a serious charge in academia, but also in professional settings." (Purdue OWL)
