What does duping mean?
Duping is the act of deliberately deceiving someone — tricking them into believing something false so they act against their own interests. As the present participle and gerund of the verb "dupe," it appears most often in contexts of fraud, scams, and confidence tricks: fraudsters are described as duping investors, shoppers, or the vulnerable into handing over money or personal information. The word carries a distinctly negative connotation, emphasizing both the dishonesty of the deceiver and the misplaced trust of the victim. It typically takes the pattern "dupe someone into doing something," which highlights that the deception leads the victim to a particular action. Related forms include the noun "dupe," meaning a person who has been deceived. Duping is a vivid, widely understood term in journalism and everyday speech for manipulation through lies rather than force.

Etymology of duping
Duping derives from the verb "dupe," which entered English in the late 17th century from the French noun "dupe," meaning a person who is easily deceived. The further origin of the French word is uncertain; one theory links it to a Germanic root related to deceit, but lexicographers generally regard its deeper ancestry as obscure. Cognate usage appears in modern French, where "dupe" retains the same sense of a deceived person.
