What is the definition of "renounce"?

The definition of "renounce" is indeed best captured by "to give up or set aside." This term is often used in contexts where an individual officially declares their abandonment of a belief, claim, or right. When someone renounces something, they are consciously choosing to reject it and no longer associate with it. This action implies a degree of intention and formality, often invoking a sense of personal or ethical conviction in the decision to relinquish that which is being renounced.

In contrast, the other options suggest active engagement or support, which does not align with the notion of renouncing. For instance, to "claim or assert" inherently involves affirming or taking ownership of something, which is the opposite of renouncing it. Similarly, "to support or promote" indicates a positive endorsement or backing of an idea or cause, while "to organize or arrange" relates to structuring or coordinating elements, neither of which pertains to the act of giving something up. Therefore, the choice that aligns with the act of renouncing is to give up or set aside.
