The primary purpose of metaphor and simile is to compare two, unlike things.

Both metaphor and simile are the figures of speech which are used while comparing two people, characters, ideas or subject. A metaphor is a hidden comparison between two things which possess at least any one idea common to each other. The things may be completely different from each other but would have either one characteristic in common to them. Simile, on the other hand, is the direct comparison between two things. It compares two things by using ‘as’ or ‘like.’ These two figures of speech are used in literary works which enhances and adds the beauty of the work.
