Lesson Transcript
Instructor: Christopher Curley
Metaphors are all around you. They're the bright sparkling lights that turn plain evergreens into Christmas trees. Learn how to spot them, why writers write with them, and how to use them yourself right here.

Definition of a Metaphor

The metaphor is the grand pooh-bah of literary terms, a kind of analogy that uses figurative language connecting one thing to another to highlight how they're alike. Metaphors are so commonplace that you probably use dozens of them every day without ever realizing it. 'Life is a journey', after all.

Why Metaphors

So let's look at a few. When you 'get up to join the rat race' in the morning, you're engaging in a kind of metaphor. 'Rat race' conjures up the image of scurrying hither-tither with no clear end in sight, a metaphor for the hustle and bustle of 9-to-5 working life. Similarly, when I say that Roger Federer (the tennis player) is a backboard, I don't mean that he's literally made of wood, but the metaphor implies that he returns his opponents' balls as surely as a backboard does.

Metaphors are powerful because they upset our expectations of a boring, literal connection between ideas, and force our brains to work harder to understand the writer's intent. Once we grasp that intent, the revelation leads to a more vivid image and/or emotional response.

The Extended Metaphor

Kin to the metaphor is the extended metaphor, which is pretty much exactly what it sounds like: a metaphor written large and lengthy to make an even deeper, more involved comparison between the subject and the thing it's being compared with. Extended metaphors often pop up in poetry and fiction, as in this passage from poet Emily Dickinson, who was a great lover of extended metaphors:

My Life had stood - a Loaded Gun -

In Corners - till a Day

The Owner passed - identified -

And carried Me away -

The poem then continues the metaphor, comparing the subject's life to that of a loaded gun, living unwanted and unused until chosen, then guarding its master, and waiting for a chance to be useful (that is, to shoot or kill someone). Extended metaphors are wonderful when done right - and this is a good one - but can quickly become unintentionally humorous if not written with a light touch.

Metaphors vs. Similes

Then we have the simile. If your comparison uses the terms 'like' or 'as', your analogy is most likely a simile and not a metaphor, even though they function similarly. Some argue that a simile is a kind of metaphor, but I'll address that in a moment.

For instance, if I want to use an analogy to explain the process of writing a story, I might say that 'The outline is like a rough blueprint for the builders to follow, while the first, second and third drafts are a town built from that blueprint that keeps getting razed by Huns, with architects improving upon each version until they finally build houses strong enough to withstand fire; what you're left with is the final draft.'

Spot all the differences? While not every simile uses 'like' or 'as,' the important thing to remember is that the metaphor makes the subject equivalent to the thing it's being compared to, while the simile qualifies the comparison, letting you know that one thing is simply 'like' another thing - not equal to it.

Writing With Metaphors

This quality of equivalence makes the metaphor a stronger device for drawing poetic and comparative links between things. But when you start writing your own metaphors, you'll want to choose your battles carefully. For instance, there's a subtle, but important difference between saying 'Your mother is a tall drink of water,' and saying 'Your mother is like a tall drink of water: slender and very refreshing.' A good metaphor forces your brain to consider something from an entirely new angle, revealing wondrous new possibilities. A bad metaphor is a shark in a Santa hat: woefully inappropriate and entirely absurd.
