Imagery refers to the use of descriptive language or visual representations to create a vivid and sensory experience for the reader. It involves using words, phrases, or descriptions that appeal to one's sense of sight, sound, touch, taste, or smell in order to convey emotions, moods, or ideas effectively. Imagery is often used in literature, poetry, and creative writing to create a more immersive experience for the reader by engaging their senses and allowing them to visualize what they are reading.
