The term "sly" refers to a person or animal that is clever in a deceptive way. Sly individuals often use their intelligence to manipulate situations to their advantage, sometimes at the expense of others. This cunning behavior can be seen in various contexts, from everyday interactions to strategic games. In literature and folklore, sly characters are often portrayed as tricksters, using their wits to outsmart opponents. Famous examples include Loki from Norse mythology and The Fox in fables. These characters highlight the dual nature of cunning, which can be both resourceful and morally ambiguous.
