a minor character whose personality or attitude contrasts with that of the main character. Juxtaposing one character against another intensifies the qualities of both, to advantage or sometimes to disadvantage. In Pride and Prejudice, for example, Lydia serves as a foil for her sister, Elizabeth Bennet. Lydia is a flight and immature flirt. In contrast, Elizabeth is sensible and insightful, qualities that she demonstrates again and again in her relationships with Darcy and other characters.
