   Syn: Deceive, Delude, Mislead.

   Usage: Deceive is a general word applicable to any kind of
          misrepresentation affecting faith or life. To delude,
          primarily, is to make sport of, by deceiving, and is
          accomplished by playing upon one's imagination or
          credulity, as by exciting false hopes, causing him to
          undertake or expect what is impracticable, and making
          his failure ridiculous. It implies some infirmity of
          judgment in the victim, and intention to deceive in
          the deluder. But it is often used reflexively,
          indicating that a person's own weakness has made him
          the sport of others or of fortune; as, he deluded
          himself with a belief that luck would always favor
          him. To mislead is to lead, guide, or direct in a
          wrong way, either willfully or ignorantly.
          [1913 Webster]
