Explanation
When you rip off someone else's ideas or work and pretend it's your own, that's plagiarism. There's a fine line between borrowing and stealing — between plagiarism and theft — and it's often open to debate what actually constitutes an outright taking of someone's material. As Einstein once said, "The secret to creativity is knowing how to hide your sources." From the Latin word for "kidnapped," when you plagiarize, you are being an intellectual thief, kidnapping someone else's ideas or words for your own purposes.
