By now you already know the basic shape of a phrasal verb and the golden rule about pronouns — see Phrasal verbs (introduction) if you need a refresher on separable vs inseparable and why ✅ turn it off is right but ❌ turn off it never is. This article goes further: verbs built from three words instead of two, the same verb meaning several unrelated things depending on context, and knowing when a phrasal verb is the natural choice and when it sounds too casual.

Quick shortcut. A phrasal-prepositional verb (three words: verb + particle + preposition) usually keeps the object right after the final preposition: ✅ put up with it, never ❌ put it up with. A single phrasal verb can also carry several unrelated meanings — only context tells you which one is meant.

Three-word phrasal verbs

Some phrasal verbs add a second small word — a preposition — after the particle, making a fixed three-part chunk: verb + particle + preposition. These are sometimes called phrasal-prepositional verbs, and English uses dozens of them constantly:

  • I can't put up with this noise any longer. (tolerate)
  • We're really looking forward to the holidays. (anticipating with pleasure)
  • We ran out of milk this morning. (used all of it)
  • She looks up to her older sister. (admires)
  • He finally got away with cheating on the test. (avoided punishment for)

In this common pattern — verb + particle + preposition + object — the object of the final preposition stays right after it, whether it's a noun or a pronoun:

  • I can't put up with it. — never ❌ I can't put it up with or ❌ I can't put up it with.
  • We're looking forward to it. — never ❌ We're looking it forward to.
Verb Meaning Example
put up with tolerate She won't put up with any more delays.
look forward to anticipate happily I'm looking forward to seeing you.
run out of use all of something We ran out of time.
get away with avoid punishment for You won't get away with that twice.
look up to admire Younger players look up to her.
come up with think of, produce He came up with a great idea.

This isn't a universal rule for every three-word combination, though — some, like talk someone out of something or fix someone up with something, place the first object in the middle instead. It's best to learn each three-word verb's own pattern as you meet it, the same way you'd learn any other phrasal verb.

A useful detail about look forward to: because it ends in the preposition to, an -ing form follows if a verb comes next, not a bare infinitive — ✅ I'm looking forward to seeing you, never ❌ I'm looking forward to see you. This is the same to + -ing pattern that trips learners up elsewhere too (see Gerunds & infinitives: advanced patterns for more verbs and expressions that behave this way).

One verb, several meanings

At this level, the hardest part usually isn't the grammar — it's that a single phrasal verb can carry two, three, or more meanings that have nothing to do with each other, and only the surrounding sentence tells you which is meant.

take off

  • The plane took off an hour late. (leave the ground)
  • She took off her coat. (remove clothing)
  • His career really took off after that film. (suddenly become successful)

run out / run out of

  • We ran out of milk. (used all of it — run out of + a noun object)
  • Time is running out. (about to end — run out alone, with no object)

get over

  • It took weeks to get over the flu. (recover from illness)
  • I still can't get over how kind she was. (be amazed by, in retrospect)
  • He never really got over losing that match. (emotionally recover from)

pick up

  • Can you pick up the kids after school? (collect someone)
  • I picked up a bit of Spanish while I was there. (learn casually)
  • Sales picked up in December. (improve, increase)

There's no grammatical trick for telling these apart — only the context, and gradually building a mental list of each verb's common meanings. A good learner's dictionary is worth more here than any rule, since it will number the separate meanings for you.

Figurative vs literal

Many phrasal verbs started out describing a literal, physical action and later picked up a figurative meaning that has drifted away from it — often the figurative sense is the one you'll hear far more often in everyday English:

  • break down: literally they broke down the old door (destroyed it by force); in a common mechanical sense, the car broke down (stopped working); figuratively, talks between the two sides broke down (failed) or she broke down in tears (became overwhelmed with emotion).
  • fall through: literally, he fell through the ice (a physical fall); as an idiomatic phrasal verb, almost always figurative — our plans fell through (didn't happen after all).
  • come across: literally she came across the room to speak to me (physical movement); idiomatically, I came across an old photo (found it by chance); figuratively, he comes across as very confident (gives an impression).

When you meet a new phrasal verb, it's worth asking whether the sentence around it makes sense literally — if not, it's almost certainly the figurative meaning, and that's usually the one worth memorising first, since it's the harder one to guess.

Formal vs phrasal: choosing your register

Many phrasal verbs are simply the everyday, neutral way to say something — carry out research, put forward a proposal, and take into account all sit comfortably in formal writing too. But some phrasal verbs do lean casual, and formal writing — a report, an essay, an official email — often reaches for a single-word equivalent with the same meaning instead, usually from Latin or French:

More everyday / conversational Often more formal / precise
put off postpone
find out discover
look into investigate
throw away discard
come up with devise / propose

Neither column is "more correct" — the choice is about register, not grammar. We need to look into this is perfectly natural in a work email to a colleague, while We need to investigate this fits a formal legal report better — the phrasal version isn't grammatically wrong there, just noticeably more casual for that context. Using only formal one-word verbs in casual conversation can sound stiff and unnatural; leaning too heavily on the conversational option in a formal document can read as too casual. Native speakers move between the two constantly depending on who they're talking to — this is a skill worth building the same way you'd build vocabulary, not a rule with a single right answer.

Common mistakes

  • I can't put up it with any longer. → ✅ I can't put up with it any longer. (in this pattern the object comes last, after both particle and preposition)
  • I'm looking forward to see you. → ✅ I'm looking forward to seeing you. (look forward to ends in the preposition to, so a following verb needs the -ing form, not the bare infinitive)
  • She never got over to lose the match. → ✅ She never got over losing the match. (get over + -ing, no extra to)

Quick check

The correct option for each sentence is one of the two choices given.

  1. I really can't put up with / put with up his constant complaining.
  2. We're looking forward to see / seeing you next week.
  3. She never quite got over / got over to losing that match.
  4. In a formal report, "investigate" is a more formal equivalent of the phrasal verb ______.
Show answers
  1. put up with — the object comes right after the full three-word verb.
  2. seeinglook forward to takes an -ing form after it, not the bare infinitive.
  3. got over — no extra to before the -ing form.
  4. look into — same meaning, more conversational register.

Key takeaways

  • A three-word phrasal-prepositional verb (verb + particle + preposition, like put up with or look forward to) usually keeps the object right after the final preposition, at the very end — though a few, like talk someone out of something, place an object in the middle instead.
  • Look forward to and similar verbs ending in a preposition take an -ing form after them, not a bare infinitive: looking forward to seeing you.
  • Many phrasal verbs carry several unrelated meanings (take off, run out, get over, pick up) — only context tells you which one is meant.
  • Phrasal verbs often started with a literal meaning and picked up a figurative one — the figurative sense is usually the more common one in everyday speech.
  • Many phrasal verbs are perfectly neutral, but some lean conversational; a handful have a one-word formal equivalent (put off / postpone) better suited to reports, essays, and official writing.
