the poet uses imagery, language that evokes a physical sensation produced by one of the five senses – sight, hearing, taste, touch, or smell. Although the effect can be quite complex, the way images work is simple. When you read the word red, your memory of the various red things that you have seen or heard about determines your visualization of the image. In addition, the word red may have emotional associations, or connotations, that define your response. A red sunset, for example, can have a positive connotation or a negative one depending on whether it is associated with a pleasurable experience or with air pollution. By choosing an image carefully, poets can not only help to create pictures in a reader’s mind, but also suggest a great number of imaginative associations These associations help poets to establish the atmosphere or mood of the poem. The falling snow in “Stopping by Woods on a Snowy Evening”, for example, creates a quiet, almost mystical mood.
