Word of the Week #9

Dupe (verb)
Originates somewhere in the late 17th and early 18th century, possibly from a word for the hoopoe, a bird that is believed to be quite stupid. The transitive verb means to trick someone, to make a dupe out of someone. The noun dupe means a person that is easily fooled, or is used by someone more dominant. E.g. "I feel so duped!"
