Plagiarism involves copying or closely imitating another author's work and presenting it as one's own without giving proper credit to the original author. It is wrong because the original author who put in hard work and thought is being robbed of credit, while the plagiarizer may receive undue recognition. Plagiarism also hampers learning, as by copying work students do not fully engage with the material and ideas, leading to poor understanding and potential failure in the future. While plagiarism may seem easy, it ultimately does a disservice to students by preventing them from gaining the intended knowledge and skills.
