This is the way I wrote essays in school - only the first sentence has anything to do with the title, the rest is just generic wikipedia copy-paste.
I'd never do that.
Plagiarism is the representation of another author's language, thoughts, ideas, or expressions as one's own original work.[1][2] In educational contexts, there are differing definitions of plagiarism depending on the institution.[3] Plagiarism is considered a violation of academic integrity such as truth and knowledge through intellectual and personal honesty in learning, teaching, research, fairness, respect and responsibility, and a breach of journalistic ethics[4] It is subject to sanctions such as penalties, suspension, expulsion from school[5] or work,[6] substantial fines[7][8] and even imprisonment.[9][10]
Generally, plagiarism is not in itself a crime, but like counterfeiting, fraud can be punished in a court[11][12] for prejudices caused by copyright infringement,[13][14] violation of moral rights,[15] or torts. In academia and industry, it is a serious ethical offense.[16][17] Plagiarism and copyright infringement overlap to a considerable extent, but they are not equivalent concepts,[18] and many types of plagiarism do not constitute copyright infringement, which is defined by copyright law and may be adjudicated by courts.
Not all countries hold the same beliefs about personal ownership of language or ideas. While some, such as India and Poland, consider plagiarism to be a crime liable for imprisonment,[19] in other countries the reiteration of another professional's work can be a sign of respect or flattery.[20] Students who move to the United States and other Western countries from countries where plagiarism is not frowned upon may find the transition difficult.[21]
