An image in poetry refers to descriptive language that appeals to the senses—sight, sound, touch, taste, or smell. It helps readers visualise scenes, emotions, or ideas, and often provides insight into the underlying message or theme of the poem.

Poets use imagery to illustrate or reinforce central ideas. For example, images of decay might reflect themes of death or impermanence; images of light might suggest hope or truth. Thus, when analysing a poem, examining the imagery often reveals the theme the poet is exploring.
