derogate

You're probably familiar with derogatory, the adjective meaning "expressing a low opinion," but you may not be as well-acquainted with the less common verb, derogate. Both words can be traced back to the Late Latin word derogatus, which is the past participle of the verb derogare, meaning "to detract" or "to annul (a law)." Derogare, in turn, derives from the Latin word for "ask," rogare. Derogate first appeared in English in the 15th century. Derogatory was adopted in the early 16th century, and has become much more popular than the verb. Other derogate relatives include derogative, derogation, and derogatorily.
