Phrasal Verbs
📖 Prefer the grown-up version? Read the adult edition →
You've probably heard a teacher say, "Right, everyone — hand in your homework and then we'll look at the results of the test." Nothing strange there. Except — try explaining out loud what "hand in" actually means. Your hand doesn't go anywhere. It means "give to the teacher." You know this instinctively. You've known it since you were about six.
Here's where it gets trickier. You say things like:
- "Can you turn off the light?"
- "My friends fell out yesterday."
- "I need to hand in my homework."
You'd never say "Please deactivate the light" or "My friends had a disagreement." That's not how anyone actually talks — unless they're trying to sound like a Dalek.
Here's the thing: phrasal verbs are right at the heart of real English. But they play by rules that aren't always obvious, and those rules can genuinely trip you up:
- Sometimes the little word can move: "Turn off the light" / "Turn the light off."
- Sometimes it can't: "I came across a good video." (Never "I came a good video across.")
- Sometimes you need two little words stuck together: "I can't put up with him."
And then a teacher tells you phrasal verbs are "too informal" for an essay, and you're left wondering what on earth you're allowed to write.
Nobody's born knowing this. The good news is that phrasal verbs follow real patterns — and once you can see separable and inseparable verbs for what they are, sentences that used to feel like guesswork start to feel like something you can actually reason through.
Before you read on, here's where we're heading. By the end of this article, you'll be able to: - Explain what a phrasal verb is, and spot one hiding in an ordinary sentence. - Tell separable phrasal verbs from inseparable ones, and place objects correctly in both. - Use pronouns (it, him, them) in exactly the right spot, every time. - Handle three-word phrasal verbs like put up with and look forward to with confidence. - Choose between a casual phrasal verb and a more formal single-word verb when your writing needs to sound more grown-up.
Beginner (Foundation)
Let's start right at the bottom, with what a phrasal verb actually is — and why it's different from a verb that just happens to have a preposition standing near it.
What is a phrasal verb?
A phrasal verb is a verb joined to one or two small words — usually things like up, off, on, out, in, away, down — that together make a new meaning. Grammar books call that small word a particle.
Compare:
- "Please sit." (just the verb "sit")
- "Please sit down." (verb + particle = a slightly different, more specific instruction)
Or these pairs, which show the same words doing two completely different jobs:
- "She looked up at the clock." (literal — she looked in an upward direction)
- "She looked up the word in a dictionary." (phrasal verb — "look up" means search for information)
Same little word, entirely different job. The whole verb-plus-particle group counts as one unit of meaning — not two words glued together by accident, but a genuine team.
More everyday examples:
- "Turn off your phone."
- "Can you look after my cat?"
- "He gave up football."
- "She ran into her teacher in town."
If you couldn't have guessed the meaning just by adding up the individual words — "run into" doesn't mean "run" plus "into a wall" — you're almost certainly looking at a phrasal verb.
Particle or preposition?
Those little words often look exactly like prepositions, because on the surface they are the same words. But they're doing a different job depending on the sentence.
- Phrasal verb: "He turned off the radio." (off is part of the verb's meaning — turned off = switched off)
- Ordinary preposition: "He put the mug on the table." (on is just showing position; there's no "put on" idiom happening here)
If the small word is glued to the verb's meaning, it's a particle, and you've got a phrasal verb. If it's simply showing where, when, or how something happens, it's behaving as an ordinary preposition. That distinction has its own dedicated home in our article on prepositions vs particles, so I won't repeat the full mechanics here — for now, trust your ear. If it can be looked up in a dictionary as one expression ("turn off," "give up," "run into"), it's a phrasal verb.
Separable vs inseparable: the first idea
Some phrasal verbs let their object sit in the middle. Others insist on staying stuck together.
Take turn off:
- "Please turn off the TV." → "Please turn the TV off." ✅
Both versions work. That means turn off is separable.
Now try come across:
- "I came across a great video." → "I came a great video across." ❌
That sounds wrong, and your ear knows it before any rule does. Come across is inseparable — the pieces refuse to be pulled apart.
At this stage, don't worry about memorising long lists. Just get into the habit of spotting phrasal verbs, and noticing whether the object can move into the middle or not.
Common Mistake: Assuming any verb + small word is automatically a phrasal verb. "I put the book on the table" isn't one — "put" and "on" aren't fused into a single new meaning here. It's just an ordinary verb with a preposition showing where the book went.
Quick recap: - A phrasal verb = a verb + one or two small "particle" words, working together as one unit of meaning. - The particle can look identical to a preposition, but it's doing a different grammatical job. - Some phrasal verbs let the object move into the middle (separable); some don't (inseparable). - If splitting the pieces sounds wrong, it's probably inseparable — trust your ear at this stage.
Intermediate (Development)
Now let's get properly hands-on: where exactly does the object go, and what happens when that object is a pronoun like it or them?
Separable phrasal verbs: where the object goes
With separable phrasal verbs, you usually have three moving parts: verb, particle, object. Take turn off:
- "Turn off the light." → verb – particle – object
- "Turn the light off." → verb – object – particle
Both are completely correct. Native speakers use both constantly, often just picking whichever feels right in the moment.
Now here's the rule that actually matters, the one that fixes almost every mistake in this area: when the object is a pronoun (it, him, her, them, us), it has to sit in the middle. No choice this time.
- "Turn it off." ✅
- "Turn off it." ❌
Say that second one out loud. It sounds wrong immediately — and that's your own grammatical instinct doing real work, long before anyone taught you the rule.
More examples:
- "Take off your shoes." / "Take your shoes off." → "Take them off." ✅ (never "Take off them")
- "Write down the answer." / "Write the answer down." → "Write it down." ✅ (never "Write down it")
Pro-Tip: If the object is short — especially a pronoun — English speakers almost always slide it into the middle. "Put it on." "Hand it in." "Pick him up." Get used to that shape and it'll start to feel automatic.
Common separable phrasal verbs worth knowing: turn off/on, pick up, take off, write down, put away, give back, throw away. Notice how many of these turn up in instructions — at home, in class, on signs.
Inseparable phrasal verbs: don't split them
Now compare:
- "I ran into my teacher in town." (never "I ran my teacher into...")
- "She looked after the baby." (never "She looked the baby after.")
- "We came across an old photo." (never "We came an old photo across.")
Here, verb and particle stay welded together, and the object — noun or pronoun — always comes after the whole unit.
Common inseparable phrasal verbs: look after, run into, come across, get over, look for, look into. With pronouns, the pattern holds exactly the same way:
- "She looked after him."
- "I ran into her."
- "We came across it."
The pronoun never sneaks into the middle here — there is no middle to sneak into.
Three-word phrasal verbs
Some phrasal verbs come with two particles glued on:
- "I can't put up with this noise."
- "She's looking forward to the holidays."
- "He gets on with his classmates."
- "We need to catch up with our homework."
These three-word phrasal verbs are always inseparable, and — this is the part people forget under pressure — the object always goes right at the very end, after both particles:
- "I can't put up with this noise." / "I can't put up with it."
- "She's looking forward to the holidays." / "She's looking forward to it."
You never drop a particle, and you never wedge the object between them:
- "I can't put with this noise." ❌ (missing "up")
- "I can't put it up with." ❌ (object in the wrong place)
- "I can't put up with it." ✅
The two small words act as a fused pair. If you're ever unsure whether something is a genuine three-word phrasal verb or just a stray sequence of prepositions, a good dictionary will mark it clearly — the fuller mechanics of that distinction belong to our articles on prepositions vs particles and dependent prepositions, so that's your next stop if you want to go deeper.
Common Mistake: Trying to move the pronoun into the middle of a three-word phrasal verb: "I can't put it up with." ❌ Keep all three parts — verb and both particles — glued together, with the pronoun sitting right at the end: "I can't put up with it." ✅
Quick recap: - Separable: the object can go after the particle or in the middle ("turn off the light" / "turn the light off"). - With pronouns and separable verbs, the pronoun must sit in the middle ("turn it off"). - Inseparable: verb + particle stay glued; the object comes after the whole thing ("ran into her"). - Three-word phrasal verbs never split; the object goes right at the end, after both particles. - A good dictionary tells you whether a phrasal verb is separable — use it like a friend, not a last resort.
Advanced (Mastery)
Now for the layer that actually helps with exams and sharper writing: style, register, and a few genuine edge cases.
Phrasal verbs vs single-word verbs
In speech and casual writing — texts, messages, chatting with mates — phrasal verbs are the natural choice:
- "The match was called off."
- "We need to sort out this mess."
- "He finally owned up."
In more formal writing — essays, reports, exam answers — there's often a single, more formal word waiting in the wings:
- "The match was cancelled." [US: canceled]
- "We need to resolve this issue."
- "He finally confessed."
The meaning isn't always identical, but it's close enough, and the single word usually reads as more precise and more polished — the kind of thing exam markers quietly notice.
That doesn't mean stripping every phrasal verb out of your essay. That just makes your writing stiff and a bit self-conscious. Ask instead: is this an important, formal moment in the piece (an opening claim, a conclusion)? Lean formal there. Is it dialogue, or a relaxed narrative passage? Phrasal verbs will sound completely natural.
Pro-Tip: When you learn a new formal verb — "investigate," say — try to pair it with the everyday phrasal verb that means roughly the same thing ("look into"). Build yourself a little mental list of these pairs, and you'll always have a formal and an informal option ready to reach for.
Subtle differences in meaning
The phrasal verb and its formal twin aren't always perfect matches:
- find out vs discover — "find out" is everyday and usually about information ("I need to find out what time the train leaves"); "discover" sounds weightier, often about something genuinely new ("Scientists discovered a new planet").
- put off vs postpone — "put off" is what you say about your own homework; "postpone" is what gets said about meetings and events on a notice board.
Reading widely is what sharpens your ear for these tiny shades of difference — you'll start noticing which writers reach for which option, and why.
Phrasal verbs and stress
In spoken English, the particle often carries the stress: "Why did you give UP?" "We can't just TURN OFF the alarm." "I'll LOOK AFTER the dog." That stress signals to a listener that this is a phrasal verb doing its idiomatic job, not just a verb with a stray preposition tagging along. Leaning on the particle when you speak in an exam or presentation genuinely makes your English sound more natural.
Phrasal verbs that change meaning entirely
Some combinations carry more than one meaning depending on context:
- take off — remove ("Take off your shoes"); leave the ground ("The plane took off"); become suddenly successful ("Her channel really took off").
- pick up — lift ("Pick up your bag"); collect someone ("I'll pick you up at 8"); learn casually ("You pick up a lot of language from games").
You work out which meaning applies from context. Don't assume the first meaning you learned is the only one lurking in a dictionary entry.
Common Mistake: Assuming one phrasal verb = one fixed meaning. Many carry three or more, and only context — or a good dictionary — will tell you which one is in play.
Quick recap: - Phrasal verbs suit speech and informal writing; single-word verbs often suit formal essays better. - Some phrasal verbs and their formal twins aren't quite identical in meaning or feel. - In speech, the particle usually carries the stress ("give UP," "turn OFF"). - Many phrasal verbs carry several distinct meanings — context decides which one you're looking at.
UK vs US Usage
Because I'm writing from Bristol, this whole article is in British spelling — colour [US: color], organise [US: organize], and so on. The genuinely good news is that the structure of phrasal verbs — separable, inseparable, three-word, pronoun placement — is identical in British and American English. Nothing you've just learned changes depending on which side of the Atlantic you're on.
- UK & US: "Turn it off." (never "Turn off it")
- UK & US: "I can't put up with it." (never "I can't put it up with")
Where things shift is in which phrasal verb people reach for, and occasionally in spelling of the formal alternative:
- UK: "The meeting was called off." US: also common, though "canceled" (single-word, US spelling) turns up more often too.
- UK: "He rang up his friend." US: more likely "He called his friend" — no particle at all.
- UK: "Please fill in the form." US: "Please fill out the form." Same idea, different favourite.
Spelling differences mostly appear in the single-word alternatives, not the phrasal verbs themselves:
- UK: "The event was cancelled." US: "The event was canceled."
So if you're reading American books or watching American shows while studying in a UK school (or the other way round), don't panic. Your phrasal-verb skills transfer perfectly. You might just swap "fill in" for "fill out" depending on the audience.
Quick recap: - UK and US English share exactly the same phrasal-verb grammar. - A handful of phrasal verbs are more common on one side of the Atlantic than the other. - Spelling differences affect single-word alternatives, not the phrasal verbs themselves. - Word order rules never change between the two varieties.
Key Takeaways
- A phrasal verb is a verb + one or two particles that together create a new, often unpredictable meaning.
- Separable phrasal verbs allow the object in the middle or at the end; pronouns must go in the middle.
- Inseparable phrasal verbs (including three-word ones) never split — the object always comes after the whole unit.
- Phrasal verbs are natural in speech and casual writing; single-word verbs often suit formal essays better.
- UK and US English share identical phrasal-verb structure, with only small differences in preference and spelling.
Check Your Understanding
1. Underline the phrasal verb and say whether it's separable or inseparable. a) She looked after her little brother. b) Please turn off your phone. c) I'm really looking forward to the trip.
2. Rewrite each sentence using a pronoun, keeping the word order correct. a) Turn off the TV. → use "it" b) I ran into my cousin yesterday. → use "her" c) I can't put up with this noise. → use "it"
3. Choose the more formal option for a school essay. a) The experiment was put off / postponed. b) We will look into / check out this problem. c) The speaker pointed out / indicated several issues.
4. Correct the mistakes. a) I can't put it up with. b) She looked the baby after. c) I need to find the answer out.
5. Is the small word a particle (part of a phrasal verb) or an ordinary preposition? a) He walked up the hill. b) He gave up smoking. c) She ran into the classroom.
Answer Key
1. a) looked after — inseparable. b) turn off — separable. c) looking forward to — inseparable, three-word.
2. a) Turn it off. b) I ran into her yesterday. c) I can't put up with it.
3. a) postponed. b) look into. c) indicated.
4. a) I can't put up with it. b) She looked after the baby. c) I need to find out the answer.
5. a) preposition (direction, "up the hill"). b) particle (phrasal verb "give up"). c) depends on meaning — if it's literal direction into the room, it's a preposition; if it means "met by chance," it's a phrasal verb.
