Plagiarism is using the works of others without proper documentation of the original source.
The word plagiarism is derived from the Latin word plagiarius, which means kidnapper. Plagiarism, a form of cheating, carries severe penalties that begin with failing an assignment or course and can end with dismissal from the college and legal liability.
Plagiarism is more than using the exact words of others without crediting the original source. In academia, simply paraphrasing the ideas of others without giving credit is also plagiarism. Citations are used to give credit to others for their words and ideas. In your academic work, citations also validate your papers, presentations, and assignments by showing where you got your information, and help distinguish your original ideas from others.
Plagiarism extends to non-textual mediums, such as speeches, data, films, and photographs that you might include in your assignments.
