Did you know?
     "Peremptory" is ultimately from Latin "perimere," which 
means "to take entirely" 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" --
"prae-" ("before") plus "emere." "Preemptive" means "marked by 
the seizing of the initiative" (as in "a preemptive attack").
