Definition of Plagiarism

But before checking for plagiarism everyone should know, What Is Plagiarism?

“The act of pretension where you take one’s words and make them your own it can include ideas, thoughts, or any material that you can see/hear and make a copy of.”

If we talk in a legalistic manner then taking someone’s copyright and claiming it to be yours is unintentional plagiarism.


The concept of thinking that, self-plagiarism is only copying some other’s paintings or borrowing someone else’s unique idea. In my thoughts like “copying” and “borrowing” can cover the seriousness of the offense.

According to the Oxford Dictionary Plagiarism is:

“The practice of taking someone else’s work or ideas and passing them off as one’s own”

In precise words, plagiarism is an act of fraud. It involves both stealing someone else’s artwork and lying approximately it in a while.

This entire method differs from traditional plagiarism detection methods that use string-matching techniques and provide an approximate estimation of plagiarism that needs to be more accurate.
