Imagery in literature involves the use of descriptive language that resonates with readers and helps them to better imagine details in stories. Imagery can also imbue symbolism into literary works. It depicts emotions, sensations, movements, and sensory details. Although the short story "Cat in the Rain" by Ernest Hemingway employs the author's famous "iceberg" approach to prose, in which only the bare essentials are written and many subtleties take place beneath the surface, there are several examples of vivid imagery. I'll point out some of these for you so that you can choose which one you want to use to answer the question.
In the first few paragraphs, Hemingway uses intense visual imagery to set the scene of the hotel in the rain. He points out that the room of the couple is on the second floor facing "the public garden and war monument." He writes that artists like the area for its palm trees and bright hotels. He describes the rain dripping from the palm trees, water pooling on the paths, and waves crashing on the shore.
Another vivid image is of the cat crouching under a green table. It is trying to make itself compact so it won't get wet.
There is a mix of emotional and sensual imagery in Hemingway's description of the wife's impression of the hotel owner. She appreciates his dignity, the way he serves her, the manner in which he receives complaints, and his large hands and aged heavy face.
Finally, there is evocative imagery in the wife's assessment of herself and expression of her desires. She uses a mirror to look at her profile from all angles and then wonders if she should grow out her hair. She explains that she wants to be able to pull it back tight and make a knot with it. She wants "a kitty to sit on my lap and purr when I stroke her." She also wants a table with silver and candles. Through all of this imagery, she is expressing her dissatisfaction to her husband, but he seems to be indifferent to her needs and desires.
Read over these various examples of imagery in the story, and then decide which one you would like to use to answer the question.
