The dictionary defines an analogy as a “similarity in some respects between things that are otherwise dissimilar.” In each of the questions contained in this section, you will find a pair of related words. These words
are separated by a colon, like this:

fish : scales

Read that to yourself as if the colon were the words “is to”—“fish is to scales.” Then, as you read through the possible answers, add “as” to the beginning of each answer—“fish is to scales as horse is to barn,” and so forth.
Look at those words and try to figure out how they are connected to one another. For example, what is the connection between the words fish and scales? Obviously, a fish is covered with scales; now think of two other words that share a similar relationship. A good example of this would be bird and feathers. The similarity between these two unrelated pairs of words is an analogy. The best way to approach an analogy question is to make up a sentence that describes the relationship between the first two words and find another pair in the choices that would fit into that same sentence. A fish is covered with scales, as a bird is covered with feathers.
