Who is referred to as a "plagiarist"?

The term "plagiarist" specifically describes someone who takes the ideas, writings, or creative works of another person and presents them as their own, without proper attribution or acknowledgment. This is a serious ethical violation in academic and creative fields as it undermines the original creator's work and misrepresents the plagiarist's own efforts.

In contrast, the other choices do not align with this definition. A person who creates original works is celebrated for their creativity; an individual who edits others' work is typically engaged in constructive criticism or publishing; and someone who teaches others is spreading knowledge and facilitating learning. Each of these roles contributes positively to the discourse of ideas and creativity, whereas a plagiarist undermines those contributions by appropriating them improperly.
