Szymborska does not use the literary device of metaphor in her work. Metaphor is a figure of speech that compares two unrelated things without using "like" or "as." It is used to create vivid and imaginative descriptions by equating one thing with another. However, Szymborska's poetry is known for its precise and straightforward language, and she often relies on concrete and literal descriptions rather than metaphorical ones. Instead, she employs other literary devices such as imagery, enjambment, caesura, and personification to enhance her poems.
