Analogy:
A similarity or comparison between two different things or the relationship between them. The comparison is often between two things in which the complex is explained in terms of the simple, or something unfamiliar is associated with something more familiar. The comparison suggests that if two things are alike in certain respects, they will probably be alike in other ways as well. Analogies can make writing more vivid, imaginative, or intellectually engaging. They must be used effectively to persuade, but logically they prove nothing

Example:
"Dumb gorgeous people should not be allowed to use literature when competing in the pick-up pool. It's like bald people wearing hats." - Matt McGrath from Broken Hearts Club


Explanation:
This analogy compares one thing with something that it shouldn't be associated with, and compares this one thing with another. In this case, dumb gorgeous girls and literature, compared with bald people and hats. This analogy allows the reader to see that dumb gorgeous people should not be allowed to use literature. The analogy allows you to clearly see this because everyone knows bald people wearing hats is ridiculous, they are trying to cover up their real self.
