dupe

To dupe someone is to trick them into believing something that is not true. It usually suggests that one person is clever or dishonest, while the other is too trusting for a moment. You might hear it in serious cases, like a scammer cheating someone out of money, or in lighter moments, like a prank that briefly fools a friend. The word can also be a noun: a dupe is a person who has been easily fooled. In both uses, the idea is the same: someone is led the wrong way and believes it.

The verb "dupe" means to deceive or trick someone into believing something false. It usually carries the sense that the deception worked fully: the person did not just hear a lie, but actually accepted it. Picture a smooth talker spinning a convincing story until the listener takes fiction for fact. That is the heart of the word: one person is misled, and another person makes that happen on purpose.

The history of the word is interesting too. English borrowed it from French, where dupe referred to a gullible person. That sense still matters today, because dupe can also be a noun meaning someone who has been fooled or used by another person. In that way, the word names both the act and the victim.

You might hear the word in serious contexts involving fraud, propaganda, or manipulation: "He was duped by a fake charity." It can also appear in lighter situations, such as a harmless surprise or prank, though it still suggests that someone was genuinely taken in. Whether used as a verb or a noun, the word points to successful deception and to the human tendency to trust what seems believable.
