Comparison is a rhetorical or literary device in which a writer compares or contrasts two people, places, things, or ideas. In our everyday life, we compare people and things to express ourselves vividly. So when we say, "as lazy as a snail," you compare two different entities to show similarity i. e. someone’s laziness to the slow pace of a snail.
