A metaphor is a figure of speech that describes a subject by asserting that it is similar to another object. Metaphors are useful because they allow one to conveniently convey much meaning with very few words by transferring properties from one concept to another. Metaphor is so pervasive and common in everyday language that some believe all words may have originated from a metaphor. Furthermore, “given the importance of language among mental faculties, metaphor is likely a key element of reasoning and thinking in general.” Being able to construct and understand metaphors may be an essential feature of the human mind.
