Did You Know?
Peremptory is ultimately from Latin perimere, which means "to take entirely" or "destroy" and comes from per- ("thoroughly") and emere ("to take").
Peremptory implies the removal of one's option to disagree or contest something. It sometimes suggests an abrupt dictatorial manner combined with an unwillingness to tolerate disobedience or dissent (as in "he was given a peremptory dismissal").
A related term is the adjective preemptive, which comes from Latin praeemere-from prae- ("before") plus emere.
Preemptive means "marked by the seizing of the initiative" (as in "a preemptive attack").
