Syn: To reprehend; chide; rebuke; scold; blame censure.
Usage: Reprove, Rebuke, Reprimand. These words all
signufy the expression of disapprobation. To reprove
implies greater calmness and self-possession. To
rebuke implies a more excited and personal feeling. A
reproof may be administered long after the offience is
committed, and is usually intended for the reformation
of the offender; a rebuke is commonly given at the
moment of the wrong, and is administered by way of
punishment and condemnation. A reprimand proceeds from
a person invested with authority, and is a formal and
offiscial act. A child is reproved for his faults, and
rebuked for his impudence. A military officer is
reprimanded for neglect or violation of duty.
