* "I was a discord in Gateshead Hall" (Chapter 1): This statement, while not a literal truth, emphasizes Jane's feeling of alienation and isolation within the Reed family. The hyperbole emphasizes her sense of being an outsider.
* "My heart beat fast, I drew my breath short" (Chapter 12): Jane's description of her reaction to Mr. Rochester's proposal portrays her emotional state in an exaggerated way, highlighting the intensity of her feelings.
* "I am a discord in Gateshead Hall: I am, I know, a discord in Thornfield Hall" (Chapter 27): Jane's statement repeats the earlier hyperbole, but this time applies it to her current situation at Thornfield. The repetition reinforces her internal struggles and the feeling of being an outsider despite her growing affection for Mr. Rochester.
* "He was my husband: I was his wife: and he was a murderer" (Chapter 27): This statement, while not entirely hyperbolic, is an exaggeration of Jane's perception of Mr. Rochester. She struggles to reconcile his actions with her love for him, emphasizing the intensity of her emotional turmoil.
While not the central stylistic device, hyperbole serves to heighten emotional impact and reveal deeper psychological states in Jane Eyre. Brontë uses it sparingly, choosing instead to build tension and emotion through more nuanced language and character development.
