Metaphor is a figure of speech that describes the object by stating one object as another thing. The purpose is to compare the features between two so to clear or explain the idea. In literal meaning, it does not make sense, rather amusing and funny.
Example:
Metaphors help to explain the idea in a vibrant and vivacious way.
Take these famous metaphor examples:
Although both simile and metaphor are used to compare between two objects and make writing vivid, interesting and lively, yet these are different in a way that metaphor states something is something else, whereas, simile explains something is like or similar to something else in a specific quality.
Often, metaphor is used loosely to mean any kind of symbolism. In literature, there are many other types of metaphors too: implied, sustained, and dead metaphors.
Implied metaphor is a type of metaphor where one object is not directly stated as other object, rather comparison is extracted from the characteristics denoted to the object.
Example:
(See in Literary device)
Extended metaphor is also called sustained metaphor. The term “extended metaphor” refers to a comparison between two unlike things that continues throughout a series of sentences in a paragraph, or lines in a poem. It is often comprised of more than one sentence, and sometimes consists of a full paragraph. This literary device is helpful in creating vivid imagery in the reader’s mind.
Example:
“Bobby Holloway says my imagination is a three-hundred-ring circus. Currently, I was in ring two hundred and ninety-nine, with elephants dancing and clowns cart wheeling and tigers leaping through rings of fire. The time had come to step back, leave the main tent, go buy some popcorn and a Coke, bliss out, cool down.” (Dean Koontz, Seize the Night. Bantam, 1999) Here extended metaphor is comparing writer’s imagination with the circus.
Metaphors are a useful descriptive tool, but when the metaphorical meaning of a phrase has overcome the original image, it is said to have become a dead metaphor.
Dead metaphors are also known as frozen metaphors and historical metaphors.
Examples:
A mixed metaphor occurs when two or more metaphors, which are inconsistent or contradictory, are combined in a way that can create confusion, humor, or unintended meaning. This typically happens when different imagery or ideas are improperly fused.
Examples:
Merges two unrelated metaphors: sharks smelling blood and taking control of a bull.
A humorous blend of "It's not rocket science" and "It's not brain surgery.
