Do you know where the word plagiarise comes from? I do, and it's very interesting:
plagiarize or plagiarise
v. take (the work or an idea of someone else) and pass it off as one's own.
- DERIVATIVES plagiarism n. plagiarist n. plagiaristic adj. plagiarizer n.
- ORIGIN C18 (earlier (C17) as plagiarism): from L. plagiarius 'kidnapper'.
I wrote that definition myself.
