What does plagiarism mean?

The use of another person’s words, concepts, or creative creations without giving due credit or recognition to the original author constitutes plagiarism.

  • Direct plagiarism is copying and pasting someone else’s work verbatim without attribution or quotation marks.
  • Paraphrasing Plagiarism: Restating someone else’s ideas or work in your own words without proper citation.
  • Self-plagiarism: presenting your previous work as new or original without acknowledging that it has been previously published or submitted elsewhere.
  • Mosaic plagiarism is piecing together various sources and blending them without proper attribution to create a new work.

On your site or anyone else’s, you may not utilize copied content. Don’t forget to give credit to the original author or website if you must borrow a few words or phrases.
