Metaphor

In practice

A metaphor works because the reader does the connecting. Call a marriage "a cold war" and nobody pictures tanks; they picture two people who no longer speak, keep score and wait for the other to blink. Four words carry what a paragraph of description would.

On the page, a metaphor has to earn its place. Prose and poetry can stop to admire an image, but a screenplay's action lines are read for what the camera will see, so a metaphor there should sharpen a picture rather than replace it. In dialogue, a metaphor tells us how a character thinks: a soldier, a chef and a gambler will reach for different ones to describe the same fear.

The common mistakes are clichés, which no longer make anyone see anything, and mixed metaphors, which start in one image and finish in another ("we'll burn that bridge when we come to it" is a joke for exactly that reason). Choose one comparison, make it specific, and let it do its work once.

A metaphor that tells us who is speaking

Rosa never says "I'm afraid of losing the last thing that ties me to them." The starter says it for her: something alive, inherited, that needs daily care. It also comes from her world, so the metaphor characterizes her while it carries the argument, and Danny's answer is an action rather than a reply.

What a metaphor is

A metaphor is a figure of speech that says one thing is another: "all the world's a stage," "her voice was music," "the classroom was a zoo." Literally, each statement is false. Figuratively, it is true in a way the reader grasps at once, because the second thing lends its qualities to the first.

Critics call the two halves the tenor and the vehicle. The tenor is the subject being described (the world, her voice, the classroom) and the vehicle is the image it borrows (a stage, music, a zoo). A strong metaphor picks a vehicle whose qualities fit the tenor in a surprising but immediately clear way.

Metaphors come in several familiar kinds. An extended metaphor carries one comparison across a passage or a whole work, as Shakespeare's "All the world's a stage" speech does through the seven ages of man. An implied metaphor never states the comparison ("she barked orders at the staff" makes her a dog without saying so). A dead metaphor has been used so long it reads as plain language: the leg of a table, the heart of the matter.

Metaphor vs. simile

A simile makes the comparison openly, with "like" or "as": "her voice was like music." A metaphor drops the signal word and makes the claim outright: "her voice was music." Both compare unlike things; the metaphor is bolder because it asks the reader to accept an identity rather than a resemblance.

The choice changes the effect. A simile keeps the two things apart and invites the reader to notice how they are alike, which suits a narrator or a character who is being careful. A metaphor fuses them, which suits certainty, emotion or a character who sees the world through one lens. "Life is like a box of chocolates" from Forrest Gump is a simile; a character who says "life is a box of chocolates" would sound more sure of it.

A quick test: if the comparison uses "like" or "as," it is a simile. If one thing simply is the other, it is a metaphor. "I slept like a baby" is a simile; "I was a log all night" is a metaphor.

Metaphor examples in film and literature

Literature is full of famous ones. Romeo says "Juliet is the sun," turning her into the center of his world and the source of his light. Emily Dickinson writes that "'Hope' is the thing with feathers," making hope a small bird that sings without asking for anything. In The Great Gatsby, the green light at the end of Daisy's dock becomes a metaphor for everything Gatsby wants and cannot reach.

Film turns metaphor into images. In The Shawshank Redemption, Andy plays an opera record over the prison speakers and the men in the yard stop to listen; the music is freedom, briefly and illegally. In Parasite, the stairs that the Kim family keep descending stand for their place in the social order, and the flood that pours down them makes the point without a line of dialogue.

Dialogue metaphors define characters. "The world is a business, Mr. Beale," says the corporate chairman Arthur Jensen in Network, and the line tells you his whole philosophy. When you write one, ask whose metaphor it is: a comparison that could come from any character is decoration, and one that could only come from this character is characterization.

How to write a good metaphor

Start with what you want the reader to feel, not with a clever image. If a character's apartment should feel confining, look for a vehicle that is confining in a specific way: a fish tank, a waiting room, a coat two sizes too small. Each one says something different, so pick the one that carries the exact feeling.

Draw the vehicle from the world of the story or the character. A sailor's metaphors come from the sea, a teenager's from what they watch and play. This keeps the figure from sounding like the author stepping in, and it quietly builds the character every time they speak.

Then cut. One precise metaphor lands harder than three competing ones, and a metaphor repeated across a story can grow into a motif. Read the line aloud: if the comparison makes you see the thing more clearly, keep it; if you notice the writing instead of the thing, rewrite it plainly.
