What does plagiarism involve?

Plagiarism fundamentally involves presenting someone else's work or ideas as your own without proper acknowledgment. This includes copying text, images, or even ideas from another source without giving credit to the original creator. Such an act can lead to serious academic consequences, as it undermines the integrity of the educational process by not giving recognition to those whose work contributes to your learning or argument.

The other options represent practices that do not involve plagiarism. For instance, revising your own work or writing from personal experience are activities that enhance your own voice and understanding without misrepresenting someone else's contributions. Using quotes appropriately involves accurately attributing the source of the quoted material, which is a way to avoid plagiarism by giving credit where it is due.
