Understanding Metaphor
Metaphor is an analogy between to objects or ideas. Within this analogy a comparison is made that invokes imagery in the reader or listener. For instance, the metaphor Ann is a pig makes the comparison of Ann being a pig. In the mind of the audience this comparison creates the image of a pig, which is often considered a filthy creature. This graphic imagery is than applied to Ann and the negative connotations associated with the pig are now transferred to Ann.Metaphor can be used not only to conjure negative emotions but also positive feelings. The metaphor Bob is a lion conjures feelings of strength along with the imagery of the lion. This imagery is applied to Bob the same way the imagery of the Pig was applied to Ann.
Metaphor affects emotion not just through imagery but also through the use of language. By virtue of word choice metaphors can have different affects via interpretation. There are several different forms of metaphor that show these different affects.
A dead metaphor is a metaphor in which the sense of the transferred image is not present. An example of this form would be "to hold a virtue" or "to grasp an understanding". Dead metaphors use physical action as a metaphor for understanding, most do not visualize the action; dead metaphors are typically not noticeable. As a result of their lack of obviousness, dead metaphors do not conjure the same emotional response as normal metaphors (Stefano, 2007).
The extended metaphor is a form of metaphor that distinguishes a main subject for comparison. The extended metaphor also uses secondary subjects that continue the main comparison. For example, “All the world's a stage, And all the men and women merely players.” This classic line from William Shakespeare's, “As You Like It” shows the use of secondary subjects men and women as players to carry and enhance the metaphor (Stefano, 2007).
A mixed metaphor is one that leaps from a primary classification to a second classification that is different from the first. An example of this odd form of metaphor can be seen in this manner: "If one can hit the bulls-eye, the rest of the dominoes will fall like a house of cards...” This form of metaphor is often used in entertainment and is often used in colloquial language (Stefano, 2007).
Through these different forms of metaphor, meaning can be intensified or even downplayed with emotional intensity. The choice of language and its usage can create different forms of metaphor and can increase the persuasiveness and strength of a story or argument. This is perhaps the best use of the metaphor, in that it is a persuasive rhetorical device. The device can be used to bolster support or to create disagreement for an argument. The use of metaphor is widely used and is a very normal part of language. The use of metaphor, although sometimes confusing for those just learning a new language, is universally used throughout the world in every culture.
