Imagery is a literary device where authors use vivid descriptions to create a picture in the reader's mind. They use details that appeal to the five senses: sight, sound, smell, taste, and touch.
Here's an example:
"The crisp autumn air nipped at her cheeks as she crunched through the fallen leaves, their vibrant reds and oranges contrasting sharply with the deep blue sky. The scent of cinnamon and pine needles hung in the air, a familiar aroma that spoke of cozy fireplaces and warm blankets."
This excerpt uses imagery to paint a picture of a beautiful autumn day. It appeals to sight (colors, leaves), touch (crisp air), smell (cinnamon, pine), and sound (crunching).
Effective imagery helps readers feel more immersed in the story and connect emotionally with the characters and events.
