The term DEVICE FOR TRAPPING can be solved by the four-letter word WILE. A WILE is a clever trick or stratagem used to deceive or outwit someone. It is often used in a negative sense, as it implies that someone has been tricked or manipulated. Wiles are commonly used in literature and popular culture, such as in fairy tales, where the hero must use their wits to outsmart a villain. In real life, wiles are often used in negotiations or other situations where one person is trying to gain an advantage over another.
