Preventing Plagiarism

What is plagiarism?

According to the Cambridge Dictionaries Online, to plagiarize is "to use another person's idea or a part of their work and pretend that it is your own" *.

It is an act of using someone else’s ideas, words, concepts, images, sounds, formulae or data without acknowledging the source, either intentionally or accidentally. It is therefore a dishonest practice of claiming credit for something you did not do.
