Our paper will approach the concept of illness from a cultural-semiotic point of view. Our aim is to provide a deeper understanding of the images of illness in Wuthering Heights, which may also constitute a model for looking at depictions of illness in other Victorian novels as well. We have attempted to show how modalization in speech becomes a symptom (from a semiotic perspective) of illness. In other words, illness manifests itself in the sick character’s language, making it appear hallucinatory and hesitating. We have also tried to look at images of ghosts and vampires in the novel as icons of illness.
