ORIGIN: The noun guile has quite negative connotations, as it refers to the kind of knowledge and skill that can be used by comic book villains for evil and not good! People who have guile are also thought of as being wily (which is also a related word), sneaky, and deceitful. Those who are free of guile are pure and upstanding, and Henry David Thoreau affirms those feelings when he wrote: "It is the work of a brave man surely, in whom there was no guile!"
