What does duped mean?
Duped is the past tense and past participle of the verb dupe, meaning to deceive or trick someone into believing something false or acting against their own interests. It is most commonly encountered in constructions such as 'she was duped into signing the contract' or 'thousands were duped by the scam', where it highlights that the deception succeeded through manipulation rather than force. As an adjective, it describes a person who has been fooled, as in 'he was a willing duped participant' — though this adjectival use is far rarer than the verbal one. The word carries a distinctly negative connotation, implying not only dishonesty on the part of the deceiver but also gullibility or misplaced trust on the part of the victim. Duped is common in journalism, particularly in reports about fraud, phishing schemes, romance scams, and misleading advertising, making it a valuable term for anyone navigating discussions of modern deception.

Etymology of duped
Dupe entered English in the late 17th century, borrowed directly from French, where dupe meant a gullible person. The French noun is traditionally linked to de huppe, referring to the hoopoe, a bird regarded in folklore as stupid and easy to catch. From its original use as a noun for a credulous victim, English developed the verb meaning to deceive such a person, with duped emerging as its standard past form.
