Root Explanation

Spoofing originates from the slang term 'spoof', which is believed to have originated in the late 19th century, possibly from the game of 'spoof' (a card game) or from the word 'spoofer', meaning to deceive or trick. The suffix '-ing' indicates the action or process of the verb. Therefore, spoofing refers to the act of deceiving or tricking someone, particularly in the context of technology or identity.

Memory Tip

Think of 'spoof' as a way to 'deceive' or 'trick' someone, and remember that 'spoofing' is the action of doing just that.
