Examples:

“Cook had changed. He seemed restless and preoccupied. There was a peremptory tone, a raw edge in some of his dealings. Perhaps he had started to believe his own celebrity. Or perhaps, showing his age and the long toll of so many rough miles at sea, he had become less tolerant of the hardships and drudgeries of transoceanic sailing.” — Hampton Sides, The Wide Wide Sea: Imperial Ambition, First Contact and the Fateful Final Voyage of Captain James Cook, 2024

Did you know?

Peremptory comes from the Latin verb perimere, meaning “to take entirely” or “to destroy,” which in turn combines the prefix per- (“throughout” or “thoroughly”) and the verb emere (“to take”). Peremptory implies the removal of one’s option to disagree or contest something, and sometimes suggests an abrupt dictatorial manner combined with an unwillingness to tolerate disobedience or dissent, as in “employees given a peremptory dismissal.” Not to sound peremptory ourselves, but don’t confuse peremptory with the similar-sounding (and related) adjective preemptive, meaning “marked by the seizing of the initiative,” as in “a preemptive attack.”
