HOW TO AVOID PLAGIARIZED WORK

Source

1) CITE YOUR SOURCE

When alluding to an idea or Worden that's not your own, add a citation in your writing that identifies the full name of the source, the date it was published, and any other citation element that's required by the style guide you are adhering to.

2) Present your own idea

Instead of parroting the source's ideas or words, explore what you have to say about it. Ask yourself what unique perspective or point you can contribute in your writing that is entirely your own.

3) Use a plagiarism checker

While conducting your research on a topic, some phrases or sentences might stick with you so well that you inadvertently include them in your writing without a citation.
