What does "rebuke" most nearly mean?

The term "rebuke" is best understood as to reprimand or express disapproval of someone’s actions. When someone rebukes another person, they are typically pointing out something that the individual has done wrong or addressing behavior that is inappropriate or unacceptable. This action often aims to correct or admonish the individual, making it a more serious and direct form of critique than merely expressing a disagreement.

In contrast, the other options suggest positive actions or feelings. For example, to compliment someone is to praise or express admiration, which is the opposite of rebuke. Encouraging someone involves giving them support or confidence, while supporting them also implies providing assistance or backing, both of which are contrary to the disapproving nature of a rebuke. Thus, "reprimand" encapsulates the essence of "rebuke" perfectly.
