What does "repudiate" mean?

The term "repudiate" means to cast off or disown. It is used to signify the act of rejecting or denying the validity or truth of something. When someone repudiates an idea, a belief, or even a person, they are actively distancing themselves from it and refusing to accept it. This can be in the context of disavowing a claim, renouncing a relationship, or rejecting a principle.

The other options focus on contrary meanings, such as advocating for a position, accepting, or deeply understanding something, which do not align with the essence of what "repudiate" conveys. Thus, the correct understanding of "repudiate" as disowning or rejecting is fundamental in grasping its usage in various contexts.
