What is a phrasal verb?

A phrasal verb is a verb combined with one or two particles — small words like up, out, on, or with — that together create a new meaning. Most phrasal verbs are idiomatic: their meaning can't be guessed from the verb alone. "Give up" means to quit, not to hand something upward.

Definition

A phrasal verb (also called a multi-word verb) is a verb + particle construction that functions as a single unit of meaning. The particle is usually a preposition (to, with, for) or an adverb (up, down, out, off, away). Some phrasal verbs take two particles, called phrasal-prepositional verbs.

The defining feature is non-compositionality: you can’t work out the meaning from the individual words. Compare:

  • Literal: She looked up (raised her eyes)
  • Phrasal verb: She looked up the word (searched for it)

How phrasal verbs are built

English phrasal verbs come in three structural patterns:

Verb + adverb

get up, take off, give up, break down. The particle (up, off, etc.) modifies the action. Most are separable.

Verb + preposition

look at, wait for, depend on. The preposition introduces an object. Always inseparable — the object follows the preposition.

Verb + adverb + preposition

look forward to, put up with, come up with. Three-word phrasal verbs are always inseparable and highly idiomatic.

Literal vs. idiomatic meaning

This is the single biggest source of difficulty for learners. Most phrasal verbs have a figurative meaning that’s only loosely connected to the literal sense of the verb + particle. Sometimes that connection is metaphorical and learnable; sometimes it’s opaque and must be memorized.

Because the figurative meaning is primary, treat each phrasal verb as a single vocabulary item. Learning “give + up” as two words won’t tell you what the phrase means.

Why phrasal verbs matter

  • Ubiquity. Corpus studies of spoken English consistently find phrasal verbs in more than a third of utterances. Skipping them makes your English sound stiff.
  • Register. Native speakers default to a phrasal verb over its Latinate single-word equivalent in conversation: find out over ascertain, put off over postpone, get by over survive.
  • Listening comprehension. Because phrasal verbs are heavily reduced in fast speech (“gonna”, “wanna”, elided particles), you need to know the phrase to parse what you hear.
  • Tone control. Once you’re fluent, swapping between phrasal-verb and single-word forms is how you shift formality — a skill every advanced learner needs.

  3. go on — continue, happen
  4. figure out — understand, solve
  5. give up — quit, stop trying
  6. pick up — lift, collect, learn casually
  7. look for — search
  8. turn on — activate
  9. find out — discover, learn

Common learner mistakes

  • Literal translation. Translating particles one-by-one into your native language produces nonsense. Learn the phrase whole.
  • Over-separating. Some phrasal verbs can split around their object (turn the light off), others can’t (look after the kids, not look the kids after). See our separability guide.
  • Confusing similar phrases. Pick up vs pick out, break up vs break down, look up vs look up to. When two phrasal verbs share a verb or particle but carry different meaning, learn them as a contrasting pair.
  • Using formal equivalents in casual speech. “I will ascertain the answer” is grammatically perfect and socially weird. In conversation, prefer “I’ll find out.”

Frequently asked questions

What's the difference between a phrasal verb and an idiom?
A phrasal verb is a specific grammatical construction: a verb plus one or more particles (prepositions or adverbs) that function as a single unit. An idiom is any fixed expression whose meaning can't be predicted from its parts. Most phrasal verbs are idiomatic — "give up" doesn't mean handing something upward — so phrasal verbs are a subset of idioms, but not all idioms are phrasal verbs ("kick the bucket" is an idiom, not a phrasal verb).
Are all phrasal verbs informal?
Most are, but not all. Conversational phrasal verbs like "hang out" or "freak out" are informal. Many common phrasal verbs, like "carry out" (perform) or "take part" (participate), are neutral and appear in formal writing. A small set, like "ascertain" vs. "find out", have formal single-word alternatives that writers choose in academic or business contexts.
How many phrasal verbs are there in English?
Estimates vary. The Cambridge Phrasal Verbs Dictionary lists around 6,000 entries; Oxford's is similar. Phrasalyze indexes roughly 5,000, focused on the set that learners actually encounter from CEFR A2 through C1. Native speakers typically use a few hundred actively and recognize far more.
Can I translate phrasal verbs literally into another language?
Almost never. Because phrasal verbs are idiomatic, their particles carry meaning that doesn't survive word-for-word translation. "Put up with" in Chinese isn't "放上面和" — it's 忍受 (tolerate). Always learn each phrasal verb as a single lexical unit with its own meaning, not by translating its parts.
Do I need to learn phrasal verbs to be fluent in English?
Yes, for spoken and informal English. Research on native conversation consistently finds phrasal verbs in more than a third of utterances. Avoiding them makes English sound stiff or bookish. Prioritize A2 and B1 phrasal verbs first — they cover the high-frequency everyday territory.
