Chapters 22–28 of Emily Brontë’s Wuthering Heights include numerous literary devices. Among them are simile, metaphor, hyperbole, and allusion. A simile is a comparison for effect of unlike things using “like” or “as,” while a metaphor is a direct comparison of unlike things.
Cathy uses a simile in chapter 24 to describe how she rode happily and quickly on her pony. On this ride, she was “as light as air.”
A metaphor is used in chapter 22 when Ellen tells of Cathy’s fondness for climbing into the trees and perching in a cozy angle among the branches. As a light wind blows around her, Ellen describes this spot as Cathy’s “breeze-rocked cradle.” Ellen uses another metaphor in the same chapter, describe how the trees sounded as she and Cathy made their way home in the rain, which “began to drive through the moaning branches of the trees.”
Cathy is an excitable girl who tends to use hyperbole, or extreme exaggeration for effect. In chapter 22, she exaggerates her emotional reactions and behavior in regard to her father and his ill health:
I fret about nothing on earth except papa's illness … And I'll never—never— oh, never, while I have my senses, do an act or say a word to vex him.
An allusion is a reference to a person, place, event, or idea, whether real or imaginary. In chapter 22, when Heathcliff encounters Cathy during one of her walks, he chastises her for breaking off communication with his son. He says that Linton has grown depressed or despondent because of her silence.
You dropped Linton … into a Slough of Despond.
This “slough” is a marsh or bog mentioned in John Bunyan’s A Pilgrim’s Progress. In addition to being a place, it represents and a state of mind that the hero Christian must pass on his spiritual journey.
