The question above is an example of an analogy. The word “analogy” comes from a Greek word for “proportionality.” Analogies are used to compare two things and show the relationship between those things. They are used to explain how they depend on each other.
An analogy is more complex than a metaphor or simile. The aim of an analogy is for you to understand the relationship between the independent words without an explanation. An example of an analogy is the question given above.
“The newspaper is to Media as an Airplane is to Transportation.” Other examples are “Finding the money will be like finding a needle in a haystack,” “Go is to Come as Sit is to Stand,” and “Black is to white as on is to off.”
