According to the Merriam-Webster Dictionary, plagiarism is "to steal or pass off [the ideas or words of another] as one's own: use [another's production] without crediting the source."
When writing a paper, giving an oral presentation, working on a group project, etc., you must always give credit to any outside sources that you used.
