What does reproof mean?
Reproof is a formal English noun for blame, censure, or a stern expression of disapproval directed at someone. It can name the criticism itself—“a reproof for neglect”—or the act or utterance of rebuking another person, as in “she directed a reproof toward him.” The word is chiefly encountered in formal writing, older literature, and speech that imitates those registers; in ordinary conversation, “rebuke,” “reprimand,” or “telling off” may sound more natural. Reproof tends to convey moral disapproval or the expectation of correction, so it is stronger and more formal than a mild complaint, though usually less heated than an outright denunciation. Its rarity gives it a precise, dignified quality that can enrich narrative prose, especially when describing a parent, teacher, or supervisor correcting a subordinate. Though easily confused by spelling with the related verb “reprove” and by sound with “proof,” reproof has a stable meaning: censure or a reprimand. It is also a useful reminder that English preserves formal vocabulary from the language of judgment and moral instruction.

Where does reproof come from?
Reproof entered Middle English through Anglo-French reprof, a noun meaning “blame” or “censure,” and ultimately belongs to the Latin root probare, meaning “to test” or “prove.” The Latin prefix re- contributed an oppositional or corrective sense to related forms such as reprove and reprobation. Modern English did not simply create the noun as a new re- plus proof construction, although that relationship explains its form and its connection with the verb reprove.
