Simile
A comparison between two unlike things using like or as.
A simile draws an explicit parallel, making the comparison easy to recognize. Writers use similes to clarify, to create vivid images, and to add emotional or sensory shading. Because the link is stated openly, a simile can feel more precise and controlled than a metaphor.
Example
London describes the cold and the dog’s wariness in plain comparisons that work like similes, measuring the man’s body against the indifferent power of nature.
