When you look for similarities in two things you read, you compare them.
Explanation:
Comparison is an expressive way of saying that compares something less familiar with something more commonly known.
It is a method in the literature that arises when one compares one with one based on common traits, often in an unfounded context.
Comparison is a basic and very much used style figure. Compare something unfamiliar with the known to make the unfamiliar to the wider public. It is often used in everyday conversation.
