Direct comparison
Metaphor vs simile
A metaphor states that one thing is another; a simile compares two things using "like" or "as". The connecting word is the key difference.

Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
Side-by-side comparison
| Dimension | Metaphor | Simile |
|---|---|---|
| What it is | A figure of speech stating that one thing IS another. | A figure of speech comparing two things using "like" or "as". |
| Connecting word | None — the comparison is stated as an identity. | Uses "like", "as" or a similar connective. |
| Directness | Direct and emphatic — asserts the two things are one. | Explicit and measured — keeps the two things distinct. |
| Example | "Time is a thief." | "Time is like a thief." |
| What the reader does | Infers the unstated point of comparison. | Follows the signposted comparison directly. |
| Relationship of the two things | Merged — one is described as being the other. | Separate — likened but kept apart. |
| Typical effect | Forceful, vivid, immediate. | Clear, precise, often more reflective. |
| Extended form | Extended metaphor sustained across a passage. | Epic (Homeric) simile elaborated over several lines. |
| Category | A form of figurative language. | A form of figurative language. |
A simple test to tell them apart
Look for the connecting word. If the comparison uses "like" or "as", it is a simile ("brave as a lion"). If it states outright that one thing is another, with no connective, it is a metaphor ("he is a lion"). Both compare two unlike things to highlight a shared quality, so the only structural difference is the explicit signpost. A useful way to remember it: a simile keeps the two things side by side and similar, while a metaphor collapses them into one.
Common questions
FAQ
Is a metaphor stronger than a simile?+
Neither is inherently stronger; they create different effects. A metaphor is more direct and emphatic because it asserts that one thing is another, which can feel bold and immediate. A simile is more explicit and often more precise, guiding the reader to the exact point of comparison. Skilled writers choose between them according to the tone and clarity they want.
Can a comparison be both a metaphor and a simile?+
No — the presence or absence of "like" or "as" decides which it is. "Her voice is music" is a metaphor; "her voice is like music" is a simile. The same idea can be expressed either way, but any single phrasing is one or the other, not both at once.
Are metaphor and simile both figurative language?+
Yes. Both are figures of speech and both fall under the umbrella of figurative language, which means language used beyond its literal sense. They sit alongside other figurative devices such as personification, hyperbole and symbolism, all of which create meaning through non-literal expression.
