deception (n.)

early 15c., decepcioun, "act of misleading, a lie, a falsehood," from Old French déception (13c., decepcion) or directly from Late Latin deceptionem (nominative deceptio) "a deceiving," noun of state or action from past-participle stem of Latin decipere "to ensnare, take in, beguile, cheat," from de "from" or pejorative (see de-) + capere "to take," from PIE root *kap- "to grasp."

From mid-15c. as "state of being deceived; error, mistake;" from 1794 as "artifice, cheat, that which deceives."
