You know the feeling. You've written a sentence that's grammatically sound, factually correct, and says exactly what happened. And it does nothing.
Maybe it's a student staring at a blank page, trying to describe a character's grief without writing "she was sad." Maybe it's a novelist three drafts into a scene that still refuses to breathe. Maybe it's a content writer whose paragraph reads as a list of facts stapled together. Whatever the situation, the symptom is the same: the words are correct, but they don't land.
That's usually not a grammar problem. It's a figurative language problem.
Literal language tells your reader what happened. Figurative language shows them what it felt like. And most flat writing isn't flat because the writer lacks ideas; it's flat because every sentence is doing the same literal job, in the same literal way, with no variation in texture or image. Readers don't consciously clock the absence of figurative language. They just feel that something is missing, and they move on.
This shows up differently depending on who's writing. A student learning the basics might not yet know the difference between a simile and a metaphor, and gets marked down for a device they didn't realise they were misusing. A novelist might understand the theory perfectly well but still reach for the same three comparisons in every manuscript, because building a genuinely original one under a deadline is hard. A content writer producing pages a week might not have the time to think past the first phrase that comes to mind, which is usually the most overused one available. Different problem, same root cause: not enough working knowledge of the tools that turn a correct sentence into a memorable one.
This guide covers twelve types of figurative language, with definitions, real examples, and practical guidance on when each one earns its place. You'll also get before-and-after rewrites that show a flat sentence transformed, a full breakdown of how to match devices to genre and tone, and a dedicated section on spotting and replacing the clichés that quietly undercut good writing. By the end, you'll be able to identify figurative language in what you read, choose the right device on purpose rather than by accident, and catch yourself before you reach for a phrase that's been used ten thousand times already.
Bookmark the quick-reference table near the end. And if you want to test what you've learned, there are practice exercises waiting for you further down.
Figurative language is language that departs from its literal meaning to create a specific effect: an image, an emotion, a moment of recognition. It doesn't describe things exactly as they are. It describes them as they feel, which is often more accurate than the literal version, even though it's technically less precise.
Literal language, by contrast, means exactly what it says. "The room was very quiet" is literal. It's also correct, forgettable, and does no work beyond conveying information.
Literal: "The room was very quiet."
Figurative: "The room held its breath."
Nothing factual changed between those two sentences. The room is still silent. But the second version gives the room an action, a held breath, which creates tension and a mood the first version simply doesn't have. That's the entire function of figurative language in one small example: it doesn't add new information; it adds feeling to information that's already there.
Figurative language does four things literal language struggles to do on its own. It makes abstract ideas concrete (turning "I felt overwhelmed" into "I was drowning in it"). It creates emotional resonance a reader can actually feel rather than just register. It adds rhythm and texture, so prose doesn't read like a spreadsheet. And it makes writing memorable, because a sharp image sticks in a reader's mind long after a flat sentence has evaporated.
None of this is decoration. A common misconception, especially among newer writers, is that figurative language is something you sprinkle on top of "real" writing to make it sound impressive. It isn't. It's a tool for meaning-making, the same as word choice or sentence structure. You already use it constantly without thinking about it: "I'm drowning in work," "that news hit me like a truck," "my patience is running on empty." None of those are literal, and none of them need explaining. Figurative language isn't a literary luxury. It's how people actually talk.
This is also why learning to notice figurative language in what you read is just as valuable as learning to produce it yourself. Once you start spotting the metaphor buried in a news headline or the personification tucked into a friend's text message, you start to see how much of everyday communication is already doing this work quietly, in the background, without ever announcing itself as a literary device.
There are dozens of named figures of speech if you go looking, but twelve cover almost everything a working writer needs. Rather than list them alphabetically, it helps to group them by how they work: comparison-based devices build an image by putting two things side by side, sound-based devices use the way words sound to create rhythm or texture, and meaning-based devices bend or substitute meaning itself. Understanding which category a device belongs to makes it easier to remember what it does and when to reach for it, rather than treating all twelve as a single undifferentiated list of literary terms to memorise for a test.
Each entry below follows the same format on purpose: a plain-language definition, a literary example with attribution, an everyday example, and a modern, conversational one, followed by when the device earns its place and the mistake most writers make with it. Read them in order the first time through, then use them as a reference you dip back into whenever a specific device needs a refresher.
A simile compares two unlike things using "like" or "as."
Literary: "O my Luve is like a red, red rose" (Robert Burns)
Everyday: "She was as busy as a barista during the morning rush."
Modern: "The news hit me like a freight train."
Reach for a simile when you want to make something unfamiliar feel familiar, or add a visual or sensory layer to a description. It's the most accessible device on this list and works in nearly any genre or register.
The common mistake is reaching for the first comparison that comes to mind, which is almost always a cliché, or stacking too many "like" and "as" constructions in one paragraph until the prose develops a sing-song rhythm that draws attention to itself instead of the meaning. A useful test: if the comparison could sit in any piece of writing about any subject, it's too generic. The best similes are specific to the exact scene they appear in.
A metaphor states directly that one thing is another, without "like" or "as."
Literary: "All the world's a stage, and all the men and women merely players" (William Shakespeare)
Everyday: "Time is a thief."
Modern: "Her voice was sandpaper on a rough morning."
Metaphor creates a stronger, more immediate identification than simile. Because it compresses the comparison into a direct statement, it can carry real emotional weight in very few words, which is why it suits poetry, fiction, and persuasive writing especially well.
Watch for mixed metaphors, combining two incompatible comparisons in one sentence ("we'll burn that bridge when we come to it"). It's a small slip that undermines credibility fast, because it signals the writer wasn't picturing either image clearly. If you can't hold the image in your head as a single, coherent picture, neither can your reader.
Personification gives human qualities, actions, or emotions to something that isn't human: an object, an animal, an idea, a force of nature.
Literary: "The wind stood up and gave a shout" (James Stephens)
Everyday: "My phone refuses to cooperate this morning."
Modern: "The city never sleeps."
Use personification when you want to build mood, make an abstract concept feel tangible, or add a lyrical quality to a passage. It's especially useful in fiction, where giving a setting human behaviour can do a lot of the emotional work a scene needs without a single line of dialogue. If you're working on a novel or short story and want a character's inner life to shape how the world around them behaves on the page, characterisation in fiction is worth a closer look, since strong personification often grows directly out of strong character work.
The risk is overdoing it. Push personification too far and the writing tips into whimsy, which is a problem if the tone calls for seriousness. Match the degree of personification to the weight of the scene.
Alliteration repeats the initial consonant sound in words that sit close together.
Literary: "From forth the fatal loins of these two foes" (William Shakespeare)
Everyday: "Peter Piper picked a peck of pickled peppers."
Modern: "The sleek, silver sedan slid silently through the intersection."
Alliteration creates rhythm, emphasis, and phrases people remember, which is exactly why brand names, slogans, and headlines lean on it so heavily. It also pairs naturally with patterned repetition more broadly. If you're curious about other repetition-based techniques, the rule of three in writing works on a similar principle: repeated structure trains the reader's ear to expect, and then reward, a pattern.
The common mistake is overdoing it until the sentence turns into a tongue-twister that distracts from meaning instead of reinforcing it. One or two repeated sounds per sentence is usually plenty.
Onomatopoeia uses words that imitate the sound they describe.
Literary: "The moan of doves in immemorial elms, and murmuring of innumerable bees" (Alfred, Lord Tennyson)
Everyday: "The bacon sizzled in the pan."
Modern: "The door clicked shut behind her."
It's most effective when you want to create an auditory experience or make a scene feel immediate, which is why it shows up so often in fiction and children's writing. It's less at home in formal or academic contexts, where it can feel out of place, and overusing it anywhere tends to push prose toward comic-book territory.
Hyperbole is deliberate exaggeration, not meant to be taken literally.
Literary: "I'll love you, dear, I'll love you till China and Africa meet" (W. H. Auden)
Everyday: "I've told you a million times."
Modern: "This bag weighs a tonne."
Hyperbole is your tool for humour, strong emotion, or making a point memorable, and it suits informal voice, speeches, and everyday conversation well. It's a poor fit for contexts where precision matters, academic writing, technical documentation, journalism, and overusing it anywhere eventually trains the reader to stop believing your claims. Save it for the moment that actually deserves emphasis rather than reaching for it in every second sentence.
An idiom is a phrase whose meaning can't be worked out from the literal meaning of its individual words. Its meaning is culturally established rather than logically derived.
Everyday: "It's raining cats and dogs."
Everyday: "She let the cat out of the bag."
Modern: "We're not out of the woods yet."
Idioms make dialogue and casual writing sound natural, because they're how people actually talk. The catch is that idioms are culturally specific: a phrase that's instantly clear to one reader might be baffling to another, particularly readers who learned English as a second language. Consider your audience before leaning on idiom-heavy phrasing, and if a phrase feels overly familiar, it's probably already a cliché rather than a fresh idiom. In dialogue especially, a well-placed idiom can also reveal a lot about a character's background or generation without a single line of explanation.
Allusion is a brief, indirect reference to a well-known person, place, event, or work.
Literary: "He was a real Romeo with the ladies" (referencing Shakespeare's Romeo and Juliet)
Everyday: "This project is my Achilles' heel."
Modern: "She has the patience of Job."
A good allusion adds depth efficiently, because it borrows meaning the reader already carries with them. It works well in essays, speeches, and persuasive writing, but only if the reference is one your actual audience will recognise. An allusion that needs a footnote has already failed at its one job. Test it against your specific reader, not against yourself, since the reference that feels obvious to you may not be obvious to them at all.
An oxymoron combines two contradictory terms for effect.
Literary: "Parting is such sweet sorrow" (William Shakespeare)
Everyday: "Deafening silence filled the room."
Modern: "The meeting was an open secret."
Oxymoron is at its best when the contradiction reveals something genuinely true, a feeling that really does contain two opposing things at once, not just a clever-sounding pairing of opposites. It suits poetry and reflective prose particularly well. It sits close to irony in effect, since both devices rely on a gap between what's said and what's actually true; if that territory interests you, types of irony in literature covers the related ground in more depth.
Synecdoche uses a part of something to represent the whole, or occasionally the whole to represent a part.
Everyday: "All hands on deck" (hands representing sailors or workers)
Literary: "The western wave was all a-flame" (Samuel Taylor Coleridge, wave representing the sea)
Modern: "Nice wheels" (wheels representing the entire car)
Synecdoche creates a vivid, specific image and suits poetry, literary fiction, and descriptive prose. It's frequently confused with metonymy, so it's worth being precise: synecdoche uses a literal part of the thing itself to stand in for the whole.
Metonymy substitutes a related term for the thing itself, without using a literal part of it.
Literary: "The pen is mightier than the sword" (Edward Bulwer-Lytton, pen representing writing, sword representing military force)
Everyday: "The White House issued a statement" (White House representing the presidential administration)
Modern: "Hollywood is out of ideas" (Hollywood representing the film industry)
Metonymy is common in journalism, essays, and speeches because it lets a writer reference something large and abstract, an institution, an industry, with a single concrete word. The distinction from synecdoche comes down to this: if the substituted term is a literal part of the thing, it's synecdoche; if it's merely associated with the thing, it's metonymy. This pair trips up even confident writers, so it's worth the extra second of thought before you commit to either term in a sentence that matters.
A pun plays on multiple meanings of a word, or on words that sound alike, for humorous or rhetorical effect.
Literary: "Ask for me tomorrow and you shall find me a grave man" (William Shakespeare, Romeo and Juliet, Mercutio punning on "grave" as both serious and a burial place)
Everyday: "I'm reading a book about anti-gravity. It's impossible to put down."
Modern: "The grammarian was very logical. She had a way with words."
Puns add wit and memorability, and they suit informal writing, humour, and wordplay-heavy genres. Used in a serious context, though, a pun can undercut the tone you've spent the whole piece building, so save them for moments where a little levity actually helps.
The fastest way to understand what a device actually does is to watch it happen to a real sentence. Here are four flat, literal sentences, each rewritten using a different device.
Simile Before: "She was very happy." After: "Joy spilled out of her like sunlight through a cracked door." What changed: an abstract emotion becomes a concrete image the reader can picture.
Metaphor Before: "The city was busy and noisy." After: "The city was a beehive that had just been kicked." What changed: two separate qualities, busyness and noise, compress into one image that implies both activity and agitation at once.
Personification Before: "The old house was quiet and empty." After: "The old house kept its secrets to itself." What changed: the house gains intention and mood, turning a static description into something with emotional weight.
Hyperbole Before: "The line at the DMV was very long." After: "The line at the DMV stretched back to the previous administration." What changed: the exaggeration adds humour and makes the frustration feel shared and recognisable, rather than just stated.
To apply this in your own revision, start with a flat sentence and ask what emotion or image it's actually trying to convey. Then choose a device that produces that effect on purpose, rather than reaching for the nearest comparison. The goal isn't to dress up every sentence in the piece; it's to find the handful of sentences that matter most and give them the weight they deserve.
The starting question is always the same: what do you want the reader to feel or see? Most writers skip this question entirely and just reach for whatever comparison surfaces first, which is exactly how clichés end up in a first draft. Slow down for one extra second and ask what effect you're actually after. From there, the choice narrows quickly.
Want to make something unfamiliar feel familiar? Simile.
Want a strong, immediate identification? Metaphor.
Want to build mood or make an abstract idea feel tangible? Personification.
Want humour or emphasis? Hyperbole.
Want rhythm or a memorable phrase? Alliteration.
Want sensory texture? Onomatopoeia.
Want to sound natural and conversational? Idiom.
Want depth through shared cultural knowledge? Allusion.
Want to capture a paradox? Oxymoron.
Want a vivid, specific image? Synecdoche or metonymy.
Want wit? Pun.
The fear most advanced writers carry isn't "will my writing be dull," it's "will my writing become purple." That fear is worth listening to, because it's usually correct: figurative language works best used selectively. A strong figure of speech only stands out if it's set against a backdrop of clear, literal prose. As a rough guide, one or two well-chosen figures per paragraph does more work than one crammed into every sentence. And avoid stacking multiple devices into a single sentence; one strong figure earns its place; three competing ones cancel each other out.
Different genres tolerate, and reward, different densities and types of figurative language. Poetry can sustain a much higher concentration than technical writing ever should. Fiction leans on metaphor and personification for mood. Speeches lean on alliteration and hyperbole because listeners can't re-read a sentence they missed. Marketing copy uses simile and metaphor to make abstract benefits feel tangible. Academic writing should use figurative language sparingly, and only where it genuinely clarifies rather than decorates. Getting this wrong in either direction is a real problem: too little figurative language in a novel reads as flat, but the same density transplanted into a research paper reads as unserious. The genre-by-genre breakdown further down covers this in more detail.
This is the single most useful self-check in this entire guide: read the passage aloud. If a figure of speech sounds forced, draws attention to itself rather than the meaning, or breaks the rhythm of the sentence, revise or cut it. Most problems with figurative language announce themselves the moment you hear them, even when they were invisible on the page.
Skill here comes from noticing, not just producing. Keep a running note, on your phone, in a notebook, wherever you'll actually use it, of fresh comparisons you encounter in books, songs, or overheard conversation. Over time, this becomes a personal library of images you can draw on instead of reaching for the first phrase that comes to mind, which is usually the most overused one. If you're a student or still building this instinct, try converting one or two literal sentences into figurative ones every day. It's a small habit, but it compounds fast.
It also helps to study one device at a time rather than trying to master all twelve at once. Spend a week paying attention to simile alone, in what you read and what you write, before moving on to metaphor. Complexity should build gradually, the same way any other writing skill does. Trying to juggle all twelve devices in a single draft is a fast way to end up with prose that feels overworked rather than confident.
A cliché is a figurative expression that was once fresh and has since been used so often it's lost its charge. When a reader hits "busy as a bee" or "light at the end of the tunnel," the phrase passes straight through their attention without creating an image or a feeling. It's language on autopilot, technically figurative, functionally dead.
This is the pain point advanced writers worry about most, and for good reason: clichés are easy to use without noticing, because they feel natural. That's exactly what makes them dangerous. Fluency and freshness aren't the same thing. A sentence can read smoothly and still be doing almost no work, because the reader's brain has processed that exact phrase so many times before that it no longer registers as an image at all, just as a familiar shape passing by.
A few patterns show up again and again, and knowing them gives you a practical checklist for self-editing:
"Like a" and "as a" constructions that feel overly familiar ("busy as a bee," "cold as ice," "quiet as a mouse")
Weather-based phrases ("light at the end of the tunnel," "calm before the storm")
Body-part idioms ("heart of gold," "cold feet," "all ears")
Time phrases ("at the end of the day," "time flies," "in the nick of time")
Business and workshop jargon ("think outside the box," "push the envelope," "low-hanging fruit")
Cliché | Fresh alternative |
Busy as a bee | Busy as a barista during the morning rush |
Light at the end of the tunnel | A crack of daylight in a long, dark hallway |
At the end of the day | When the dust settles |
Think outside the box | Think past the edges of the map |
Cold as ice | Cold as a landlord's handshake |
Heart of gold | A heart that leaves the porch light on for everyone |
Quiet as a mouse | Quiet as a held breath |
Time flies | Time slips through your fingers like sand |
Brave as a lion | Brave as a kid raising their hand first on the first day of school |
Blind as a bat | Blind as a phone screen in direct sunlight |
Test any alternative by reading it aloud. If it creates a specific, concrete image, it's doing its job. If it feels generic, it's just a cliché wearing a disguise, and it needs another pass.
Search your draft for common cliché markers ("like a," "as a," "at the end of the day," "think outside the box").
Identify what the cliché is actually trying to say; what's the underlying feeling or idea?
Ask what specific, concrete image could convey that same meaning in a way nobody's heard before.
Write a new comparison that's specific to your character, your context, or your situation, not a general one.
Read both versions aloud and compare the effect.
This is also exactly the kind of thing a second, more objective pair of eyes tends to catch faster than the writer who's been staring at the same paragraph for three hours. If you'd rather have someone else run this pass on a full manuscript, professional editing is built around exactly this kind of line-level refinement.
Figurative language isn't one-size-fits-all. What works beautifully in a poem can feel out of place in a business report, and the density that suits a speech will overwhelm a short story. Here's a working map of which devices belong where.
Best devices: metaphor, simile, personification, alliteration, onomatopoeia, oxymoron.
Poetry can sustain the highest concentration of figurative language of any form on this list. Metaphor and simile do the heavy lifting for imagery, personification adds emotional resonance, and alliteration and onomatopoeia build musicality into the line itself. Oxymoron is where poetry gets to hold a contradiction without resolving it. If you want to see how these devices behave across different poetic forms, different types of poems to explore are a useful next stop.
Best devices: metaphor, simile, personification, synecdoche, metonymy.
In fiction, figurative language should serve character and setting rather than showcase the writer. A detective describes a room differently than a poet would, and that difference is where voice lives. A tired parent notices different things in a kitchen than a burglar does, and the comparisons each of them reaches for should reflect that. Keep the density moderate; figurative language should deepen the story, not interrupt it. If you're working through the mechanics of a full story rather than just a scene, how to write a short story walks through the structural side of that process.
Best devices: alliteration, hyperbole, metaphor, allusion, repetition.
Speeches rely on language a listener can catch on the first pass, because there's no re-reading a sentence that's already gone. Alliteration creates phrases that stick. Hyperbole adds emotional force. Metaphor makes an abstract idea concrete in a single breath. Keep sentences shorter than you would on the page, and let the figures of speech carry more of the weight.
Best devices: simile, metaphor, alliteration, hyperbole, pun.
Marketing copy needs to be memorable and persuasive, often in a handful of words. Simile and metaphor make a product benefit feel tangible rather than abstract. Alliteration builds a slogan that sticks. Puns add shareability when the tone allows for it. Whatever device you use, keep the focus on the reader's problem and how the product solves it, not on how clever the line sounds. If your business is working through this kind of copy at scale, marketing support built specifically for authors and publishers can save a lot of trial and error.
Best devices: metaphor (sparingly), metonymy, synecdoche.
Academic writing should use figurative language rarely, and only where it clarifies rather than obscures. A metaphor like "the brain as a computer" can genuinely help a reader grasp a complex idea, but it needs to be introduced explicitly rather than assumed. Metonymy and synecdoche tend to appear naturally; "the White House" for the administration is a fixture of academic prose already. Avoid hyperbole, puns, and idiom here; they undercut the formal register the genre depends on. If precision at the sentence level matters for your thesis or paper, academic proofreading is worth having in your corner before submission.
Best devices: idiom, hyperbole, simile, metaphor.
Everyday speech is saturated with figurative language, most of it entirely unconscious. Idiom is the most common form, because it makes speech feel natural and culturally connected. Hyperbole adds humour and emphasis, and simile and metaphor slip into casual comparisons without anyone noticing. Even a text message complaining about a "nightmare" commute or a coffee that "saved" someone's morning is doing figurative work, without anyone stopping to label it. The takeaway that matters most here: figurative language isn't a literary flourish reserved for novels and poems. It's a fundamental feature of how humans actually talk to each other.
Type | Definition | Example |
Simile | Comparison using "like" or "as" | "Her smile was as bright as the morning sun." |
Metaphor | Direct comparison without "like" or "as" | "Time is a thief." |
Personification | Giving human qualities to non-human things | "The wind whispered through the trees." |
Hyperbole | Deliberate exaggeration for effect | "I've told you a million times." |
Onomatopoeia | Words that imitate sounds | "The bacon sizzled in the pan." |
Alliteration | Repetition of initial consonant sounds | "Peter Piper picked a peck of pickled peppers." |
Idiom | Phrase with meaning different from its literal words | "It's raining cats and dogs." |
Allusion | Reference to a well-known person, place, or work | "He's a real Romeo with the ladies." |
Oxymoron | Contradictory terms used together | "Deafening silence filled the room." |
Synecdoche | Part represents the whole | "All hands on deck." |
Metonymy | Related term substitutes for the thing itself | "The White House issued a statement." |
Pun | Play on words with double meaning | "I'm reading a book about anti-gravity. It's impossible to put down." |
Reading about figurative language is passive. Using it is active, and that's where the skill actually forms.
Exercise 1: Identify the device
"The classroom was a zoo."
"The leaves danced in the wind."
"I'm so hungry I could eat a horse."
"The bees buzzed busily."
"The crown announced new taxes."
Answer key: 1. Metaphor. 2. Personification. 3. Hyperbole. 4. Alliteration and onomatopoeia. 5. Metonymy.
Exercise 2: Rewrite the literal sentence
Rewrite "The room was messy" using a simile.
Rewrite "She was very tired" using a metaphor.
Rewrite "The car was old" using personification.
There's no single correct answer here. Judge your own attempt against three questions: does it create a specific, concrete image? Does it match the tone you're going for? Does it feel inevitable rather than decorative?
Exercise 3: Find figurative language in a passage
Pick a paragraph from a book you love, ideally one from your own bookshelf, and go through it line by line, labelling every figurative device you find. You'll usually find more than you expect; most working authors use figurative language constantly, without drawing attention to it. Pay particular attention to the sentences that made you pause the first time you read them; there's a good chance a figure of speech is doing the work you responded to, even if you didn't consciously notice it at the time.
Exercise 4: Create original comparisons
Write three original similes or metaphors for common experiences: waiting in line, waking up early, receiving good news. Clichés don't count. If your first instinct is a phrase you've heard before, keep going until you land on something that's actually yours.
Exercise 5: Cliché replacement
Take five clichés, from your own writing or the list earlier in this guide, and write a fresh, original alternative for each. Compare your answers against the cliché-to-original swap table above and see how your instincts measure up.
Figurative language is a tool for meaning-making, not decoration. Across the twelve devices covered here, each has its own strengths and its own common pitfalls, and clichés are the quiet enemy of fresh writing in every one of them. None of this becomes instinct overnight. It comes from noticing, practising, and reading your own work aloud often enough to hear where it's forcing something rather than earning it. The core principle to carry forward is simple: the best figurative language feels inevitable, not decorative. It serves the emotion and the meaning underneath it, builds a specific image rather than a vague gesture, and matches the tone of the piece around it. When you're not sure whether a line is working, read it aloud. If it sounds forced, cut it.
Bookmark the quick-reference table, work through the practice exercises when you've got ten spare minutes, and consider starting that running list of comparisons this week. Figurative language is a skill you build in layers, one noticed sentence at a time, and this guide will still be here when you want to come back to it. However you use it, the underlying discipline stays the same across every genre this guide has touched on: notice what a sentence is actually trying to make a reader feel, then choose the device that gets it there without drawing attention to itself. That's the whole craft, in one sentence. Everything else in this guide is just the detail underneath it.
Figurative language is language that moves away from its literal meaning to create a specific effect, an image, an emotion, or a fresh way of seeing something familiar. It's the opposite of literal language, which means exactly what it says.
The twelve covered in this guide are simile, metaphor, personification, alliteration, onomatopoeia, hyperbole, idiom, allusion, oxymoron, synecdoche, metonymy, and pun. They're grouped into comparison-based, sound-based, and meaning-based categories, depending on how each one works.
A figurative sentence uses one of these devices rather than stating something in plain, literal terms. "The room held its breath" is a figurative sentence; "the room was very quiet" is its literal equivalent.
It's used to make abstract ideas concrete, create emotional resonance, add rhythm and texture to prose, and make writing memorable. It turns information a reader has to process into an image or feeling they experience directly.
A simile compares two things using "like" or "as" ("brave as a lion"). A metaphor states directly that one thing is another, with no comparison word ("she was a lion in the boardroom"). That small grammatical shift changes a comparison the reader notices into one they feel.
Synecdoche uses a literal part of something to represent the whole, or the whole to represent a part ("all hands on deck"). Metonymy substitutes a related but separate term for the thing itself ("the White House" for the administration). If the substituted word is physically part of the thing, it's synecdoche; if it's merely associated with it, it's metonymy.
Look for language that can't be true if read literally, an object acting with intention, an exaggerated claim, two unlike things placed side by side. If a sentence would sound strange or impossible taken at face value, there's a good chance it's figurative.
Without it, writing tends to communicate information without creating any real impression. Figurative language is what makes a sentence memorable rather than merely accurate, and it's often the difference between prose a reader forgets by the next page and one they remember years later.
