Short answer: a dead metaphor is a figure of speech used so often that readers no longer see the picture inside it. Common dead metaphor examples include "the foot of the mountain," "fly off the handle," "deadline," "broadcast" and "muscle." Each began as a concrete image (a body part, a loose axe head, a prison boundary, seed scattered by hand, a little mouse) and now reads as a plain word or phrase. Below are the examples with their literal origins taken from named references, George Orwell's useful split between dead and dying metaphors, and when bringing a dead one back to life works.
What makes a metaphor "dead"
A live metaphor makes you see two things at once. "Her silence was a wall" puts a wall in your head next to the silence. A dead metaphor has stopped doing that. You read "the foot of the mountain" and think only of the bottom of a slope; no foot appears.
The metaphor did not vanish. It became the ordinary meaning, and dictionaries record that change. The Online Etymology Dictionary, read on October 2, 2026, gives foot in the sense "bottom or lowest part of anything eminent or upright" from about 1200. English speakers have used a body word for the base of things for more than eight centuries, and nobody now stops to picture a foot.
Because the image is gone, a dead metaphor is not a fault. Most of them are simply vocabulary, and you could not write a paragraph without them. The trouble starts with a different group, the one Orwell named.
Register and region: "dead metaphor" is a neutral term used in the US and the UK, in classrooms, linguistics and style advice alike.
Orwell's split: fresh, dead and dying
In his 1946 essay Politics and the English Language, as published by the Orwell Foundation (read October 2, 2026), George Orwell sorted metaphors into three kinds.
- Fresh metaphors help thought by calling up a visual image.
- Dead metaphors are harmless. In his words, "a metaphor which is technically 'dead' (e. g. iron resolution) has in effect reverted to being an ordinary word."
- Dying metaphors are the problem: "a huge dump of worn-out metaphors which have lost all evocative power and are merely used because they save people the trouble of inventing phrases for themselves."
His list of dying metaphors includes "toe the line," "ride roughshod over," "play into the hands of," "no axe to grind" and "grist to the mill." These are not fully dead, because a reader can still half-see the image. They are tired.
Most lists of dead metaphor examples mix the two groups together, and that hides the useful part. A dead metaphor ("the leg of a table") needs no fixing. A dying one ("stand shoulder to shoulder with") usually does, because it signals that the writer reached for the nearest phrase rather than the right one.
Dead metaphor examples, with the literal origin named
| Dead metaphor | The literal picture | What the reference says |
|---|---|---|
| Foot of the mountain | A body part at the base | Online Etymology Dictionary: "lowest part" sense of foot from about 1200 |
| Fly off the handle | A loose axe head flying free | Phrase Finder: American phrase, earliest main citation 1843/4; a reader note offers 1828 |
| Deadline | A line prisoners could not cross | Online Etymology Dictionary: prison-camp "dead line" 1864; newspaper time-limit sense by 1919 |
| Broadcast | Seed scattered by hand | Online Etymology Dictionary: seed sense 1767; radio sense 1922 |
| Muscle | A little mouse | Online Etymology Dictionary: Latin musculus, literally "a little mouse"; English late 14th century |
| Iron resolution | Resolve as hard as iron | Orwell's own example of a metaphor turned ordinary word |
Each one is explained below.
Foot of the mountain, leg of the table, hands of the clock
Body-part metaphors are the largest family of dead metaphors in English. The mouth of a river, the eye of a needle, the face of a cliff, the arm of a chair, the head of a department: each borrows a body word for part of a thing. The foot date above shows how old the habit is.
These are as dead as metaphors get, because there is often no other ordinary word for the part. You can say "the base of the mountain," but nothing competes with "leg" for the part of a table that holds it up.

Fly off the handle
According to The Phrase Finder's entry on "fly off the handle", read on October 2, 2026, "This is an American phrase and it alludes to the uncontrolled way a loose axe-head flies off from its handle." Its earliest citation is Thomas C. Haliburton's The Attaché; or, Sam Slick in England (1843/4): "He flies right off the handle for nothing."
A reader note on the same page, by Dewi Morgan, points to an earlier line from 1828, in a book titled Ps and Qs published by Bowles & Dearborn: "At this my heart flew off the handle." So the date depends on which part of the page you trust: the main entry says 1843/4, the reader note says 1828, and Phrase Finder has not folded the earlier date into its own entry.
Register and region: casual, US and UK. Mostly dead: few speakers picture an axe, though the image comes back as soon as someone names it.
Deadline
The Online Etymology Dictionary, read on October 2, 2026, traces "dead line" to 1864 and the American Civil War prison camps, where it was a boundary inside the stockade that prisoners could not cross without being shot. The entry quotes the 1865 trial record of Henry Wirz, commander of Andersonville prison. The modern sense arrived "by 1919 in American English newspaper jargon," meaning the last minute copy could be sent to the printer.
This is one of the clearest dead metaphor examples because the original picture is so much darker than the modern use. People say "deadline" about homework and tax returns without a thought of prison camps.
Register and region: neutral, US and UK.
Broadcast and muscle: dead metaphors inside single words
Some dead metaphors have shrunk to one word. The Online Etymology Dictionary dates broadcast to 1767 as a farming term for seed "dispersed upon the ground by hand," with a figurative sense of "widely spread" by 1785 and the radio sense in 1922. Every radio and TV broadcast is, underneath, a farmer flinging seed.
The same reference traces muscle to Latin musculus, "literally 'a little mouse,'" diminutive of mus, "mouse," in English from the late 14th century. Few people flexing a biceps think of a mouse.
These single-word cases are the hardest to spot, because nothing about the word looks figurative. You only find them in an etymology dictionary.
Dead, dying or alive? A quick test
Three questions sort most phrases.
- Is there another ordinary word for this? If not, the metaphor is dead and doing a job. "Leg" of a table, "mouth" of a river.
- Does naming the image surprise people? If "muscle means little mouse" gets a laugh of surprise, the metaphor was dead. If "break the ice" gets an "of course," it is dormant, still half visible.
- Do people misspell it in a way that changes the picture? Orwell noticed that "toe the line is sometimes written as tow the line." A misspelling like that is a sign the original image has faded and a new one is moving in. Orwell's other case is "the hammer and the anvil," used as if the anvil gets the worst of it, when "In real life it is always the anvil that breaks the hammer, never the other way about."
Errors of this kind follow a pattern: when people stop seeing the picture, they fill in a more familiar one. Our page on commonly misused idioms looks at why those errors are predictable.
When the picture dies, a story often replaces it
A dead metaphor leaves a gap: the words still look like they should mean something concrete. Folk etymology rushes in to fill it, usually with a vivid story and no citation.
"Kick the bucket" is a good case. Most readers today picture an ordinary pail, while our page on the kick the bucket origin explains why the bucket was more likely a beam. "Bite the bullet" attracts a Civil War surgery tale, and our page on where bite the bullet comes from shows that the story arrives decades too late. The lesson for dead metaphors in general: a confident story about a faded image deserves a reference check before you repeat it.
When reviving a dead metaphor works
Reviving a dead metaphor means making the reader see the literal picture again. Done on purpose, it is one of the cheapest ways to make a sentence memorable. Done by accident, it produces a laugh you did not want.
It works best in three situations.
- Humor. Take the dead image literally and push it one step: "He flew off the handle, and like any loose axe head, he took a window with him."
- Emphasis. Remind the reader of the original stakes: "This was a deadline in the old sense: cross it and you were finished."
- Poetry and close description. Let the body-part metaphor become a body again: "The road ran along the mountain's ankle, where the rock was scuffed and bruised."
Those three sentences are our own illustrations, not quotations.
It fails when the revival is accidental, which usually happens when two dead metaphors meet and wake each other up. "The foot of the project was its backbone" makes a reader picture a foot and a spine at the same moment, and neither fits. If a sentence makes you stop and see something odd, check whether two dead images have collided.
Orwell's first rule of writing in the same essay targets the dying group, not the dead one: "Never use a metaphor, simile or other figure of speech which you are used to seeing in print." Applied to dead metaphors it would be impossible to follow, because you cannot write about a table without its legs. Applied to dying ones, it is still good advice.

Frequently asked questions
What is a dead metaphor?
A dead metaphor is a figure of speech that has been used so often that readers no longer notice the image in it. "The foot of the mountain" and "deadline" are examples: both began as pictures and now read as plain words.
What are some common dead metaphor examples?
Body-part phrases (foot of the mountain, leg of a table, mouth of a river), "fly off the handle," "deadline," "broadcast" and "muscle," which the Online Etymology Dictionary traces to a Latin word meaning "little mouse."
Is a dead metaphor the same as a cliche?
Not quite. A cliche is an overused phrase that readers still recognize as figurative. A dead metaphor is no longer recognized as figurative at all. Orwell's "dying metaphors," such as "toe the line," sit in between and overlap with cliches.
Should I avoid dead metaphors in my writing?
No. Fully dead metaphors are ordinary vocabulary and cannot be avoided. The ones worth cutting are the tired, half-visible phrases Orwell called dying metaphors, which usually stand in for a more precise word.
Can a dead metaphor come back to life?
Yes. A writer can revive one by making the literal image visible again, often for humor or emphasis. It also happens by accident when two dead metaphors collide in one sentence.
