Literary Devices
High SchoolFigurative language lets writing mean more than it says. This chapter catalogues the core devices — from metaphor to irony to symbol — and shows how to identify their effect, not just their name.
Simile
- Comparison signalled by like or as.
- “Her mind was like a steel trap.”
- Keeps a polite distance: this resembles that.
- Chosen for clarity and a lighter touch.
Metaphor
- Direct identification, no like/as.
- “Her mind was a steel trap.”
- Collapses the distance: this is that.
- Chosen for intensity — bolder and more total.
Figures of comparison and substitution
- Simile — comparison using like or as: "her mind was like a steel trap."
- Metaphor — direct identification, no like/as: "her mind was a steel trap." An extended metaphor sustains the comparison across a passage.
- Personification — giving human qualities to non-human things: "the wind whispered."
- Metonymy — naming something by an associated thing: "the Crown" for the monarchy; "the White House said."
- Synecdoche — a part standing for the whole: "all hands on deck"; "wheels" for a car.
- Hyperbole — deliberate exaggeration: "I've told you a million times."
Figures of meaning and structure
- Irony — a gap between appearance and reality. Verbal (saying the opposite of what is meant), situational (an outcome contrary to expectation), dramatic (the audience knows what a character does not).
- Symbol — a concrete thing standing for an abstract idea (a dove for peace).
- Motif — a recurring image or idea that builds a theme through repetition.
- Allusion — a reference to another text, myth, or event ("he met his Waterloo").
- Imagery — language appealing to the senses.
Sound devices
Alliteration (repeated initial consonants: "wild and windy"), assonance (repeated vowel sounds), onomatopoeia (words that imitate sound: buzz, crash), and sibilance (repeated s sounds).
The mistake most readers make is spotting devices without stating their effect. Naming "this is a metaphor" earns nothing; the analysis lies in why the writer chose it and what it does to the reader. A metaphor is a claim of hidden likeness — calling grief "an ocean" imports the ocean's vastness, depth, and power to drown. The device is a machine for transferring associations; your job is to trace the transfer.
The difference between a symbol and a motif is worth fixing. A symbol is a single object carrying meaning; a motif is a symbol (or image) recurring across a work so that its meaning accumulates. A green light seen once is an image; seen five times across a novel, always as Gatsby reaches toward it, it becomes a motif that gathers the theme of unreachable longing.
These are often confused. Metaphor links two things by resemblance across different domains ("time is a thief" — time is not literally near thieving). Metonymy links two things by real association within the same domain ("the pen is mightier than the sword" — pen for writing, sword for force, both by contiguity). Resemblance vs. association is the dividing line.
Exercise: analyse the devices in a passage
"The city never sleeps; its ten thousand eyes blink through the fog, and the river drags the day's secrets out to a patient, waiting sea."
Personification: "The city never sleeps" and the "patient, waiting sea" give human states (wakefulness, patience) to non-human things — the effect is to make the environment feel alive and watchful, even faintly menacing.
Metaphor / synecdoche: "ten thousand eyes" stands for the city's lit windows (a metaphor of eyes for windows, with a numeric hyperbole); it converts ordinary buildings into a surveillance, reinforcing the watchful mood.
Personification + metaphor: "the river drags the day's secrets out to sea" imagines the river as an agent removing and concealing — "secrets" is a metaphor for the day's hidden events; the image suggests a city with things to hide.
Sound: the sibilance of "secrets … sea" and the soft -ing of "waiting" slow the line's pace, giving it a hushed, secretive tone that matches the meaning.
Overall effect: the devices cooperate to render the city as a single, sentient, secret-keeping organism — the analysis is not the list of names but this unifying claim about mood.
Now you try: analyse "Hope is the thing with feathers that perches in the soul" (Dickinson). Identify the extended metaphor (hope as a bird) and state its effect (hope as light, living, and singing without asking anything in return).
What is the difference between a metaphor and a simile — and does it matter?
AA simile signals the comparison openly with like or as ("brave as a lion"); a metaphor asserts the identity directly ("he was a lion in battle"). The difference matters because metaphor is bolder: by omitting "like," it claims the two things are one, which feels more immediate and total. A simile keeps a polite distance ("this resembles that"); a metaphor collapses it ("this is that"). Writers choose metaphor for intensity and simile for clarity or a lighter touch.
How do the three types of irony differ?
AVerbal irony is a gap between what is said and what is meant — sarcasm is its harsh form ("lovely weather," said in a storm). Situational irony is a gap between what is expected and what happens (a fire station burns down). Dramatic irony is a gap between what a character knows and what the audience knows (we see the killer hiding while the hero says "we're safe now"). All three trade on a discrepancy between two levels of awareness; they differ in who holds the two levels — the speaker, fate, or the audience.
Why does identifying a device without analysis earn little credit?
ABecause the name is not the point — the effect is. "This is alliteration" describes a feature; literary analysis asks what that feature does: how it shapes rhythm, mood, or emphasis, and how it serves the writer's larger purpose. The rule of thumb is the sentence "The writer uses X to …" — you must always be able to finish it. Device-spotting is the raw observation; the analysis is the interpretation of its purpose and impact on the reader.
What is the difference between a theme and a motif?
AA theme is the central idea or message a work explores — an abstraction like "the corrupting power of ambition." A motif is a concrete, recurring element — an image, phrase, object, or situation — that appears repeatedly and, through repetition, develops the theme. In Macbeth, blood is a motif (it keeps reappearing); guilt and the moral cost of ambition are themes. Motifs are the tangible threads; themes are the ideas those threads weave into.
