Deception is a trick or scheme used to get what you want, like the deception you used to get your sister to agree to do all your chores for a month.
Deception occurs when you deceive, a word that comes from the Latin de- meaning "from" and capere, meaning "to take." When you deceive someone, the result may be taking — like items you don't really need from people willing to give them, believing they are helping you. You may have heard the phrase "take someone for a ride." That's a way of describing deception.
