treachery: [13] Despite the passing resemblance, treachery has no etymological connection with traitor or treason. In fact, its closest English relative is trick. The word was borrowed from Old French trecherie, a derivative of trichier ‘cheat’ (source of English trick). => trick
treachery (n.)
"treasonable or perfidious conduct," c. 1200, from Old French trecherie, tricherie "deceit, cheating, trickery, lies" (12c.), from trechier "to cheat, deceive" (see trick (n.)).
