One of the many jobs of an editor is to be on the lookout for plagiarism. I don’t have a magic formula for spotting it, but I do have some tips that might help.
First off, what is plagiarism?
The dictionary definition goes like this:
“The practice of taking someone else’s work or ideas and passing them off as one’s own.”
From an editing point of view, it most often means that a text, or a piece of text, has been copied verbatim from someone else: in other words, they were not written by the person who claims to have written them.
