TLDR
Similes and metaphors both compare two things to shift meaning from literal to figurative, but a simile uses "like" or "as" while a metaphor says or suggests that one thing is another. In AP English Literature, the points come from explaining how a comparison works, not just naming it. Identify the main subject and comparison subject, then explain what traits transfer and how that builds the poem's meaning.
Why This Matters for the AP English Literature Exam
Poetry analysis is one of the harder parts of the exam for a lot of students, and figurative comparisons are everywhere in the poems you will read. Recognizing a simile or metaphor is the easy half. The skill that earns credit is explaining the function: what the comparison reveals, emphasizes, or transfers, and how it shapes tone, imagery, or meaning.
This skill supports both multiple-choice questions, where you interpret how a comparison affects meaning, and your written analysis, where you quote a figurative phrase and build commentary around it. Later units push you from recognizing what a metaphor compares to explaining how that comparison shapes your whole interpretation, so getting comfortable with it now sets you up for stronger poetry essays.
Key Takeaways
- A simile uses "like" or "as" to liken two things; a metaphor says or implies one thing is another without those words.
- In both, the main subject is the thing being described, and the comparison subject is the thing it is compared to.
- Comparisons transfer traits or qualities from the comparison subject to the main subject.
- Metaphors and similes rely on associations readers already have with the comparison subject.
- The meaning of a comparison can change based on context: who is speaking, the tone, and what is happening in the poem.
- Always move past identifying the device to explaining its function and connecting it to a claim about the poem.
Simile
A simile makes an explicit comparison using words such as "like" or "as" to liken one thing to another. A simile can clarify an image, intensify emotion, create contrast, or reveal a speaker's perspective.
A simile likens two different things in order to transfer the traits or qualities of one to the other. In a simile, the main subject is the thing being described, and the comparison subject is the thing it is compared to. For example, in "her voice is like velvet," "voice" is the main subject and "velvet" is the comparison subject. The simile transfers the softness and smoothness associated with velvet to the voice.
When analyzing a simile, ask:
- What two things are being compared?
- Which is the main subject and which is the comparison subject?
- What qualities are transferred from the comparison subject to the main subject?
- How does the comparison affect tone, imagery, or meaning?
Metaphor
A metaphor makes an implicit comparison by saying or suggesting that one thing is another. A metaphor implies similarities between two usually unrelated concepts or objects in order to reveal or emphasize something about one of them, though the differences between the two may also be revealing. Metaphors can shape a single image or organize an entire poem.
In a metaphor, just as in a simile, the main subject is the thing being described, and the comparison subject is the thing it is identified with. For example, in "time is a thief," "time" is the main subject and "thief" is the comparison subject. The metaphor transfers qualities like stealth and loss from "thief" to "time."
Metaphors draw on the associations readers already have with the comparison subject. If a poet compares hope to a flame, readers bring ideas such as warmth, light, fragility, and the possibility of being extinguished. These existing associations are what give metaphors their power, since they tap into shared experience to make meaning feel immediate.
The meaning of a metaphor depends on context. A comparison may suggest different qualities depending on what is happening in the poem, who is speaking, and what tone the surrounding lines create. For instance, calling someone a "rock" in a love poem suggests reliability and strength, but in a poem about emotional distance, it might suggest coldness or immovability. What is transferred in a metaphor is shaped by the situation the text presents.
Metaphors can make abstract ideas concrete. They can also create tension when the comparison feels surprising, unstable, or contradictory.
How to Use This on the AP English Literature Exam
Multiple Choice
When a question asks about a figurative comparison, focus on what the comparison does in context. Identify the main subject and the comparison subject, then ask which qualities transfer. Watch for answer choices that correctly name the device but misstate the effect, or that pick associations the poem does not actually support.
Free Response
In a paragraph, quote the figurative phrase, name the comparison, and explain how it develops the poem's meaning. A weak sentence stops at "the poet uses a simile to create imagery." A stronger sentence explains the effect of the comparison, like this: "By comparing the speaker's memory to a locked room, the poem presents memory as private, enclosed, and difficult to access." Always connect the device to a claim about the poem as a whole.
Common Trap
Do not assume a comparison always means the same thing. The same image can carry opposite meanings depending on tone and situation. Read the surrounding lines before you decide what traits the comparison transfers.
Common Misconceptions
- Simile and metaphor are not just "comparisons with or without like/as" for grading purposes. The point is the function, so naming the type without explaining the effect earns little credit.
- The comparison subject is not always more important. The main subject is the thing being described, and your job is to explain what the comparison reveals about it.
- A metaphor does not have a single fixed meaning. Context, speaker, and tone shape what gets transferred, so the same image can mean different things in different poems.
- Personification, imagery, and metaphor are related but not identical. Be precise about which device you are naming and what it does.
- Spotting a simile or metaphor is not analysis by itself. Identification is only the first step; commentary on its function is what matters.
