Step-by-step explanation:
According to Longman, imagery is used for its precision in conveying a particular idea, character, setting, or plot point. Imagery employs language that stimulates the senses, providing rich descriptions that allow readers to visualize and experience the text more fully. It goes beyond mere decoration and often serves a specific purpose such as establishing mood, emphasizing certain qualities, or deepening the reader's connection to the material.
