A simile A figure of speech that compares two different things explicitly, using a marker such as like, as, or than.

The strongest similes clarify, surprise, or make the familiar strange; overused ones (“as busy as a bee”) and mixed comparisons dull the effect.

Full entry →, and ask what the comparison reveals.
Why this matters
Similes turn up everywhere—in essays, speeches, headlines, advertisements, and ordinary conversation—so recognizing them is a basic reading skill. In literary analysis a simile is evidence: name its tenor and vehicle, and you can say what the comparison makes visible and whether that choice is apt, revealing, or merely automatic. That move separates real analysis from labeling. Studying similes also improves your own writing, because the gap between a fresh comparison and a dead one is often the difference between prose that sparks and prose that lies flat. And because simile sits beside metaphor A figure of speech that compares by identifying one thing with another, without an explicit marker such as like or as. Full entry →, mastering the explicit comparison makes the implicit one easier to handle in any text you meet.
The college version
The explicit comparison: what a simile is
A simile is a figure of speech that compares two different things openly, using a marker that tells the reader a comparison is happening. The familiar markers are like, as, and than: “her voice was like sandpaper,” “the hallway was as quiet as a held breath,” “the plan was more rumor than plan.” The marker matters because it keeps the comparison visible. The reader is invited to hold two items side by side—the thing being described and the thing it is compared with—and to notice what they share. Some definitions also count words such as appears or seems as possible markers, but the standard, widely documented set is like, as, and than.
The comparison should cross a gap. “Her voice was like her sister's” compares two similar things and asks almost nothing of the reader; “her voice was like sandpaper” compares a voice to an abrasive sheet, borrowing the quality of roughness and inviting the reader to feel it. That crossing of categories is what makes the figure work. When you meet a simile in a text, the first move is simply to find the marker and name the two items it joins.
Simile and metaphor: one marker apart
The distinction between the two figures is crisp. A metaphor compares without the marker, by identifying one thing as another: “her voice was sandpaper.” A simile keeps the two items separate and announces the comparison: “her voice was like sandpaper.” The first fuses; the second places side by side. Because a simile's marker is explicit, a reader can usually point to the exact moment the comparison begins, while a metaphor requires the reader to supply the act of identification.
The two devices are close relatives. Both compare unlike things, and both borrow qualities from one domain to describe another. The deciding evidence in any passage is the marker: if the comparison is announced with like, as, or than, it is a simile; if one thing is simply referred to as another, it is a metaphor. In practice this difference changes the effect. The metaphor can feel more assertive and complete—the identification is total—while the simile keeps a visible distance between subject and image, which can make the comparison feel more considered or more tentative.
Tenor, vehicle, and the effects a simile can create
The vocabulary introduced by I. A. Richards in The Philosophy of Rhetoric (1936) gives analysts precise names for the parts of a comparison. The tenor is the subject being described; the vehicle is the object whose attributes are borrowed. In “her voice was like sandpaper,” voice is the tenor and sandpaper is the vehicle. The ground—the set of shared attributes—is roughness. Analysis begins by naming all three parts, then asks the interesting question: why this vehicle? Sandpaper suggests not only roughness but friction, wear, and abrasion, a voice that might grate over time. Choose a different vehicle and the meaning shifts: “her voice was like warm honey” borrows sweetness and slowness instead. The choice of vehicle is where a simile does its work.
That choice produces the effects readers feel. A well-chosen vehicle clarifies: it borrows something concrete or familiar to make an abstraction graspable, as in “her patience wore thin like a rope fraying at the anchor.” It can make a description vivid and memorable, the traditional purpose of figurative language Language that departs from literal statement to create comparisons, images, or effects. Full entry →. It can surprise, when the gap between tenor and vehicle is wide and the shared quality is unexpected. And it can defamiliarize—the term Viktor Shklovsky coined in 1917 for art that makes the familiar strange so that readers perceive it freshly. A simile that compares a city's morning traffic to a river of cold molasses makes commuters feel the slowness again instead of simply noting it. Naming the tenor, vehicle, and ground, then testing what the vehicle adds, turns “this is a simile” into an argument about the writer's choice.
The epic simile: comparison stretched into a scene
Most similes are brief—a clause or a line. The epic, or Homeric, simile extends the comparison over several lines, developing the vehicle into a small scene of its own before returning to the subject. The form is characteristic of Homer's Iliad and Odyssey, which is why it is also called the Homeric simile, and it reappears throughout later epic poetry. Encyclopaedia Britannica describes it as an extended simile, often running to several lines, used typically in epic poetry to intensify the heroic stature of the subject and to serve as decoration.
In effect, the poet pauses the action to unfold the comparison—a warrior's charge described through a lion's, a dawn through a slow fire—and then brings the reader back to the story with the comparison enlarged. The return to the tenor (“so the army…”) shows the poet's reasoning in miniature. For analysis, the epic simile A simile developed at length over several lines, often used in epic poetry to magnify heroic action; also called a Homeric simile. Full entry → is a gift: because the vehicle is developed at length, there is more evidence to work with, and the reader can trace exactly which attributes the poet chose to borrow and which details of the vehicle do most of the work.
When similes fail: clichés and mixed comparisons
A comparison can be grammatically correct and still do nothing. Clichés such as “as busy as a bee” or “as brave as a lion” were once fresh enough to earn their keep; repeated use has drained them, so readers glide past without forming an image. The same process affects all figures: critics note that words and phrases that were once vivid images can survive as dead figures whose original aptness has been lost. The remedy is not to avoid comparison but to make it specific—“as busy as a porter at closing time” at least names a scene the reader can picture.
The other classic failure is the mixed comparison, defined in dictionary practice as a figure combining inconsistent or incongruous images. When two vehicles collide in one sentence—“her voice was like sandpaper that cut through the silence”—the images fight (abrasion against cutting) and the reader cannot tell which quality is being borrowed. Good revision keeps one vehicle running and makes sure the borrowed attributes are compatible. A simile should hand the reader a single clear picture, not a stack of competing ones.
Eli explains
The same idea, in plain words
Explain it like I’m 10
A simile is a comparison that shows its work. When a writer says “her voice was like sandpaper,” you can see the two things being held up side by side: a voice and a piece of sandpaper. The little word “like” (or “as” or “than”) is the marker that says: comparison happening here. The writer is not claiming the voice is made of sandpaper; they are borrowing one quality—roughness—and lending it to the voice. A good simile makes you see something clearly or freshly. A worn-out one, like “as busy as a bee,” is so familiar that your mind does not bother to make the picture anymore. When you meet a simile, find the marker, name the two things, and ask what quality the writer wants you to see. That is the whole trick of analysis: not just saying “that is a simile,” but explaining what the borrowed image adds.
Picture it like this
Think of a simile as holding two photographs side by side on a table. The marker word is the table. You look at the voice in one photo and the sandpaper in the other, and your eye moves between them until it finds what they share—the roughness. The comparison is right there, visible, waiting for you.
Where the picture stops working
Photographs sit still, but a simile also carries feeling and rhythm, and the writer chose the vehicle for reasons a photo frame cannot explain. The analogy shows the structure of a simile, not the judgment behind choosing one image over another.
Worked example
Consider the invented sentence “The old truck started like a lion waking from a nap—a growl, a rumble, then a long satisfied silence.” The marker is “like,” the tenor is the truck's starting, and the vehicle is a waking lion. The ground is the shared quality: a slow, powerful, rumbling beginning that stirs before it fully roars. The comparison is apt because it borrows exactly the qualities an old engine can have—weight, delay, animal power—and revealing because “waking from a nap” also hints that the truck dozes when parked and only comes alive when called on. Naming tenor, vehicle, and ground turns “it's a simile” into an argument about why the writer chose that image and what it makes the reader feel.
Key takeaway
A simile is an explicit comparison announced by a marker such as like, as, or than; analyze it by naming the tenor and vehicle and asking what the borrowed image makes visible or feels like.

Common mistakes
Calling any comparison a simile.
A simile needs an explicit marker such as like, as, or than; “her voice was sandpaper” is a metaphor, not a simile.
Confusing simile with metaphor.
Check for the marker. A metaphor identifies one thing as another; a simile keeps the comparison visible with like, as, or than.
Stopping at identification.
After naming the simile, identify tenor and vehicle and explain what the borrowed image makes visible or how it feels; that is the analysis.
Using clichéd similes.
Test whether the comparison still forms a picture; replace worn-out images such as “as busy as a bee” with a specific, fresh one.
Mixing vehicles in one comparison.
Keep one vehicle running; if the images clash, as in “her voice was like sandpaper that cut through the silence,” revise so the borrowed qualities are compatible.
Easily confused
Simile vs. Metaphor
A simile compares explicitly with a marker such as like, as, or than, keeping the two items visible; a metaphor compares implicitly, identifying one thing as another without the marker.
Tenor vs. Vehicle
The tenor is the subject being described; the vehicle is the image whose attributes are borrowed to describe it.
Fresh simile vs. Cliché
A fresh simile makes the reader form a new image or see the subject anew; a cliché is so overused that it no longer produces that effect.
