Definition:
In literature, one of the strongest devices is imagery wherein the author uses words and phrases to create “mental images” for the reader. Imagery helps the reader to visualize more realistically the author’s writings. The usage of metaphors, allusions, descriptive words and similes amongst other literary forms in order to “tickle” and awaken the readers’ sensory perceptions is referred to as imagery. Imagery is not limited to only visual sensations, but also refers to igniting kinesthetic, olfactory, tactile, gustatory, thermal and auditory sensations as well.
Example:
The gushing brook stole its way down the lush green mountains, dotted with tiny flowers in a riot of colors and trees coming alive with gaily chirping birds.
A short story with great imagery is The Scarlet Ibis by James Hurst.
