A metaphor A figure of speech that compares by speaking of one thing as another, without "like," "as," or "than." Full entry → is an implicit comparison: it speaks of one thing as though it were another, without "like," "as," or "than." When a writer says "time is a thief," they are not listing the ways time and thieves are alike; they are asking you to see time through the thief's qualities: it takes what is yours while you are not watching. Metaphors compress meaning, make the familiar strange, and reward readers who can say which parts of the comparison carry weight and which do not.
Why this matters
Metaphor is one of the most common moves in language, appearing not only in poetry and fiction but in headlines, advertising, politics, and everyday speech. Knowing how it works lets you explain what a comparison makes you see, what it leaves out, and why one image persuades where another fails. In academic writing, analyzing a metaphor is a precise way to build an argument about a text, and the terms tenor The primary subject of a metaphor: the thing being described. Full entry → and vehicle The secondary subject or image through which the tenor is presented. Full entry → give you a shared vocabulary for that work. Using metaphors deliberately also makes your own prose clearer and more memorable.
The college version
Metaphor is comparison without the connective
A metaphor is a figure of speech that compares by identification rather than by stating a similarity. The Poetry Foundation's glossary describes it as a comparison made directly or less directly, but in any case without pointing out a similarity with words such as "like," "as," or "than." Where a simile An explicit comparison built around "like," "as," or another comparative construction; covered in its own lesson. Full entry → holds two things apart and connects them with an explicit word ("her voice was like a chime"), a metaphor fuses them: "her voice was a chime in a dark hallway." Nobody mistakes this for a literal claim about vocal chords; the identification is understood as a way of seeing. The invented example "time is a thief" treats time as though it were a person who takes things. The comparison is implicit, which is what makes metaphor compact: the writer does not argue the likeness, the reader supplies it. This definition is the one to hold on to, because every other feature of metaphor follows from it. A metaphor is not a claim that the two things are identical; it is an invitation to look at one thing through another for the duration of the comparison.
Tenor and vehicle: naming the two parts
To analyze a metaphor you need names for its parts. The critic I.A. Richards, in The Philosophy of Rhetoric (1936), called the subject being described the tenor, and the image it is described as the vehicle. The Stanford Encyclopedia of Philosophy uses the same distinction, speaking of the metaphor's primary subject and its secondary subject, the latter introduced to enrich how we think and talk about the former. In "time is a thief," time is the tenor and the thief is the vehicle. In an invented line like "grief was a cellar with a locked door," grief is the tenor and the cellar is the vehicle. Analysis proceeds in three steps: name the tenor, name the vehicle, then say which qualities travel from one to the other. The transfer is selective. OpenStax's writing guide observes that figurative language compares one aspect of things that in other ways are completely different, and that selectivity is the point: the thief brings stealth and taking, not a criminal trial; the cellar brings darkness and confinement, not moisture or stairs. Mapping is the reader's active work, and two readers may reasonably weight different qualities, which is why strong metaphor analysis states the mapping explicitly and supports it with the text. Metaphor also earns its keep through economy: a whole relationship is compressed into a few words. And it can surprise: the wider the gap between tenor and vehicle, the more striking the flash of recognition when a shared aspect appears.
Extended, mixed, dead, and live metaphors
Metaphors differ in scale and in freshness. An extended metaphor A single comparison sustained across several sentences or an entire passage. Full entry → sustains one comparison across several sentences or an entire passage; the Stanford Encyclopedia describes such unitary likenings as sprawling over multiple successive sentences. A writer might keep returning to the same image, adding new details that stay within it. Extended metaphors build coherence and can organize a whole paragraph, poem, or speech. A mixed metaphor A metaphor that leaps from one image to a second image inconsistent with the first. Full entry →, by contrast, leaps from one identification to a second inconsistent with the first. The invented sentence "our team is on the ropes, and unless we weather the storm we will never cross the finish line" mixes boxing, weather, and racing in a few words; the clash is usually comic or confusing. Sometimes the effect is deliberate, and careful writers can mix images to controlled effect, but in student writing an unintentional mix is a signal that the images are not being tracked. Freshness is a separate axis. A dead metaphor A metaphor whose comparison has become so familiar that readers no longer notice the image. Full entry → is one whose transferred image has become so familiar that it goes unnoticed: "grasp a concept" and "the foot of the mountain" are metaphors of holding and of the body that most readers never picture. A live metaphor A metaphor whose comparison still registers and invites interpretation. Full entry → is one whose comparison still registers and asks to be interpreted. Dead does not mean bad; these worn comparisons carry everyday meaning efficiently. Live metaphors are where analysis has the most work to do, because the text is asking you to see something anew.
Conceptual metaphor, and the neighbors: simile and analogy
George Lakoff and Mark Johnson, in Metaphors We Live By (1980), argued that metaphor is not only a stylistic ornament but a conceptual matter: we think of one kind of thing in terms of another. The Stanford Encyclopedia summarizes this as the view that metaphor is at bottom a matter of thinking of one thing as and in terms of another, through standing cross-domain mappings such as "love is a journey." Lakoff and Johnson's own example "argument is war" points to how we speak about arguing: we attack positions, defend claims, win and lose debates, and abandon weak ground. The theory, presented here as a theory and attributed to its authors, suggests that metaphors do not just decorate thought but organize it. It is one influential framework, not a rule that every metaphor carries a hidden ideology, and scholars of language do not all accept its strong form. Two neighbors deserve a brief distinction. A simile is an explicit comparison built around "like," "as," or another comparative construction; it keeps the two things separate, and it has its own lesson here. An analogy A comparison based on a likeness or parallel relationship, often spelled out at length rather than implied. Full entry → is a comparison based on a likeness or parallel relationship, usually spelled out at length: a heart is like a pump, a state is like a ship. A metaphor can be understood as the compact form of such a comparison, leaving the likeness implicit. When you meet any of the three, the useful question is the same: what is being compared to what, and which qualities are doing the work?
Eli explains
The same idea, in plain words
Explain it like I’m 10
A metaphor is a shortcut for comparing without saying "like." "Time is a thief" does not mean time goes to jail; it means time takes moments away from you while you are not paying attention. You do not have to list the ways they are alike, because the comparison is implied. Every metaphor has two parts: the tenor, which is what you are really talking about (time), and the vehicle, which is what you call it (a thief). The trick is that only some of the vehicle's qualities apply: time steals, but it does not get caught. Figuring out which qualities transfer is the fun of reading a metaphor. An extended metaphor keeps one picture going for many lines; a mixed metaphor suddenly switches pictures, which is usually funny or confusing. A dead metaphor is one everyone has used so much that the picture has worn away, like "grasp an idea."
Picture it like this
A metaphor is like a handshake that skips the introduction: it assumes you already know who the other person is, and in one move you are connected. A simile is the full introduction, spelling out how two things are alike, while a metaphor just grabs the resemblance and runs with it.
Where the picture stops working
The handshake idea breaks down because a metaphor does more than connect two things: it rearranges how you see the first one, and it can keep working across a whole text. A metaphor is also not neutral — the image a writer chooses quietly steers how you feel about the subject, which is exactly why analyzing it matters.
Worked example
In the invented lines "Summer was a slow train: it stopped at every small town, let the dust settle, and never once checked its watch," the tenor is summer and the vehicle is a slow train. The qualities that transfer are slowness, frequent stops, and indifference to time; the writer leaves out the train's tracks, passengers, and schedule. Naming the mapping shows how the metaphor works: it makes summer feel drawn out and aimless rather than golden or joyful. The comparison is live, not dead, because the image still registers, and it is extended because the train picture carries through three clauses instead of one. A different vehicle, such as a bonfire, would have mapped entirely different qualities, which is why the choice of image is worth commenting on.
Key takeaway
A metaphor speaks of one thing as another, mapping selected qualities from vehicle to tenor without "like" or "as"; the best analysis names both parts and says which qualities the comparison carries, and which it leaves behind.

You’ll learn to
- Define metaphor as an implicit comparison that speaks of one thing as another without "like," "as," or "than."
- Distinguish the tenor (the subject being described) from the vehicle (the image it is described as).
- Explain how a metaphor works by mapping selected qualities from the vehicle onto the tenor, with economy and surprise.
- Identify extended metaphors and mixed metaphors and explain their different effects.
- Analyze a metaphor's effects, including whether it is live or dead, and recognize conceptual metaphor as an attributed theory of how metaphor shapes thought.
Common mistakes
Calling any comparison a metaphor, even one that uses "like" or "as."
Check for the explicit connective. A comparison with "like" or "as" is a simile; a metaphor states the identification without it.
Confusing tenor and vehicle.
Ask what the passage is really about: that is the tenor. The image it is described as is the vehicle. In "time is a thief," time is the tenor and the thief is the vehicle.
Reading a metaphor as a literal claim.
"Time is a thief" is not a statement that time commits crimes. Treat the identification as a way of seeing, and say which qualities are meant to transfer.
Assuming every quality of the vehicle applies to the tenor.
Metaphors map selected qualities. State which qualities carry over and which the comparison leaves behind, and support that choice with the text.
Treating "dead" as an insult.
Dead metaphors are ordinary and useful; the label describes whether readers still notice the image, not whether the phrase is good or bad.
Easily confused
Metaphor vs. Simile
A metaphor identifies one thing with another implicitly ("time is a thief"); a simile holds the two apart with an explicit "like" or "as." Simile has its own lesson.
Metaphor vs. Analogy
A metaphor compresses a comparison into an identification; an analogy spells out a likeness or parallel relationship, often at length, as in "a heart is like a pump."
Live metaphor vs. Dead metaphor
A live metaphor's comparison still registers and invites interpretation; a dead metaphor's image has become so familiar that readers no longer notice it.
