The lack of definition is because of the nature of plagiarism. It is not restricted to a particular identity because it can arise in your work in different ways. It could be Intentional or deliberate where the student intentionally and knowingly copies another’s work.

It could also be unintentional or accidental; it is where someone unintentionally follows the general structure and precise wording used by another author.

Apart from the two main categories, there are two more. Plagiarism can also arise in your work as a result of copying your own previously written article. For instance, if a student is required to submit an assignment mid-course regarding a topic and it again has to write about it during the final dissertation. Plagiarizing a section from the previous paper would lead to plagiarism.
