Imagery is about description; a description that provides depth to otherwise flat depiction. It is intended to enhance sensory experiences and to bring a narrative to life. It also makes the readers identify themselves with the story and picture it from a different level.
A visual prompt is the most common form of imagery. Here the writer gives a vivid description of an action and a character, rather than just a basic description. This enhanced description enables the reader to see the actions and the characters clearly in his/her mind.
The use of senses is also important, especially in fiction stories. It adds good features to the story, allowing the reader to imagine and identify with the characters. Some of these senses include auditory, olfactory, tactile, gustatory and kinesthetic. Auditory imagery involves using the sense of sound in the story. Olfactory imagery creates a sense of smell in the story. Tactile imagery creates a sense of touch. Gustatory imagery employs the sense of taste while kinesthetic imagery employs the sense of movement.
Other forms of imagery include the use of colours, similes, and metaphors. Effective use of imagery does not mean over using it. The writer should get the perfect choice of words that give powerful descriptions that remain enjoyable and memorable to the reader. It also requires the writer to be creative and imaginative.
