Reprove, rebuke, reprimand, admonish, reproach, and chide all mean to criticize. Reprove implies an often kindly intent to correct a fault. Rebuke suggests a sharp or stern criticism (as in "In the interview, the candidate sternly rebuked the agendas of those running against her"). Reprimand implies a severe, formal, often public or official rebuke ("He was reprimanded before the ethics committee"). Admonish suggests earnest or friendly warning and counsel ("The assistant manager was admonished to control expenses"). Reproach and chide suggest displeasure or disappointment expressed in mild scolding ("The teacher reproached the student for tardiness" and "The child was chided by his nana for untidiness"). Incidentally, the resemblance of reprove to prove is not coincidental—both words can be traced back to the Latin probare ("to test" or "to prove").
