peremptory

the word peremptory originates from the latin peremptorius, meaning "deadly, decisive, final," which itself derives from perimere, "to take entirely, destroy." this verb is a compound of per- ("thoroughly") and emere ("to take"). the original legal sense in english, referring to a final and decisive judgment that "takes away" all further debate, emerged in the late middle ages. over time, the meaning broadened from describing an irrevocable legal order to characterizing any dismissively authoritative manner that "takes through" or cuts off all opposition. thus, the modern sense of a brusquely commanding attitude retains the core idea of a decisive action that precludes any further discussion.

Structure: per (through, thoroughly) + empt (take, buy) + ory (adjective suffix) - per: a latin prefix meaning "through," "thoroughly," or "completely." - empt: from the latin root emere, meaning "to take," "to buy," or "to acquire." - ory: a latin-derived suffix forming adjectives meaning "pertaining to" or "serving for."
