The document discusses imagery and sensory details in literature. Imagery uses vivid language to describe objects, actions, places, or ideas by appealing to the senses. Sensory details specifically draw on the five senses of sight, sound, smell, touch, and taste. Effective imagery helps readers visualize and experience what characters experience in a story. Examples from Where the Red Fern Grows are provided to illustrate imagery related to sight, sound, smell, and touch.
