Perfidious

per•fid•i•ous/pərˈfidēəs/ Adjective: Deceitful and untrustworthy. Synonyms: treacherous - traitorous - unfaithful – disloyal Words which describe the human condition are powerful words in your vocabulary. Benedict Arnold is a famous traitor in history. Let’s go back in our mental movies, our personal time machine. Arnold was a General for the American Continental Army in the Revolutionary War who switched to the British forces. Because of the way he changed sides, his name quickly became a byword in the United States for treason or betrayal. Some see PERFIDIOUS and draw a blank. I teach my students to make a mental film. And when they make a mental film, they see a picture of Benedict Arnold and the word PERFID IOUS is owned forever.
