To derogate someone means to do what?

To derogate someone means to detract from their reputation or to belittle them. It involves saying or doing something that diminishes their worth or value in some way. This term is often used in contexts where someone is criticized or insulted, which results in a negative assessment of their character or actions.

The other options suggest positive actions—uplifting or enhancing someone implies building them up, while supporting someone indicates providing assistance or encouragement. These are contrary to the notion of derogating, which is fundamentally about diminishing or insulting. Thus, the correct choice reflects an action that negatively impacts someone's standing.
