Etymology: "Rebuker" is formed by adding the suffix "-er" to "rebuke," which makes it an agent noun, a word for the person who performs the action. Someone who rebukes is a rebuker, much as a baker bakes and a teacher teaches. The base word "rebuke" entered English in the Middle Ages, borrowed from Old French "rebuker," meaning to beat back or check, and built on the prefix "re-" (back) and "buc," an element linked to the idea of striking or pushing. The original sense was physical or forceful, a driving back, before it came to mean a sharp verbal criticism. Because the suffix is simple and productive, "rebuker" is a plain formation rather than a term with a dramatic backstory. Its meaning follows directly from the verb: anyone who delivers a firm reprimand or correction to another's conduct is a rebuker.
