Merriam-Webster provides the following definitions:
Plagiarize: to steal and pass off the ideas or words of another as one's own. It comes from the Latin plagiarius 'kidnapper.'
Copyright: the exclusive legal right to reproduce, publish, sell, or distribute the matter and form of something (such as a literary, musical, or artistic work).
How is plagiarism different from copyright?
Common ways to avoid plagiarism include:
You want to use, verbatim, a short paragraph of someone else’s work in your own paper. You decide it falls under “fair use” and include the paragraph, word for word. Not an example of copyright infringement. However, if you do not cite it, thereby presenting it as your own work (either intentionally or not) - that is Plagiarism.
