Phrasal Verbs: What They Are and How to Use Them

Reviewed by the Grammarlyzer Editorial Team · Our Review Standards · Published June 13, 2026 · Updated July 16, 2026

Classify the meaning and object pattern before choosing the word order.

⚡ Quick Answer

In Cambridge's narrow classification, a phrasal verb combines a main verb with an adverb particle: turn off, give up, or take off. Learner materials also use the label broadly for related multi-word verbs such as prepositional look after and three-part come up with. Meanings are often difficult to predict from the parts, so learn the meaning and object pattern together.

Working method: Record the exact meaning, whether the verb takes an object, and where a noun or pronoun object can go. The label alone does not decide the word order.

🔑 Key Takeaway

With a separable verb, a noun object can usually sit before or after the particle: turn the TV off or turn off the TV. A personal pronoun must go in the middle: turn it off. A prepositional or three-part verb keeps its object after the final preposition: look after them, come up with it.

Phrasal verb Meaning Type Example
give up quit / stop trying intransitive in this use "Don’t give up."
put off postpone separable "Put off the meeting."
look after take care of prepositional; inseparable "Look after the kids."
run into meet by chance prepositional; inseparable "I ran into Sam."
take off leave the ground / remove separable / intransitive "Take off your shoes." / "The plane took off."

Quick Comparison

Type What it means Quick Check
Transitive Needs an object Can you ask "____ what?" Use an object (turn off the TV).
Intransitive Takes no object Does it stand alone (the plane took off)? No object needed.
Separable A noun object can split the verb and particle Use either "turn the TV off" or "turn off the TV"; use "turn it off" with a pronoun.
Prepositional The preposition requires an object after it Keep the object after the phrase: "look after the dog" or "look after it."
Three-part Verb + particle + preposition Keep the object after all three parts: "come up with a plan" or "come up with it."

Common Mistakes

Putting a pronoun after the particle in a separable verb

❌ Incorrect:

"I wrote down it before I forgot the address."

✓ Correct:

"I wrote it down before I forgot the address."

With a separable phrasal verb, a personal-pronoun object goes between the verb and particle. A noun phrase can go either side (wrote down the address or wrote the address down), but write wrote it down.

Splitting an inseparable verb

❌ Incorrect:

"We ran an old friend into at the airport."

✓ Correct:

"We ran into an old friend at the airport."

In Cambridge's terminology, run into, look after, and come across are prepositional verbs: their objects follow the preposition. Check an unfamiliar entry in a learner's dictionary instead of transferring the separable pattern.

Translating the parts literally

❌ Incorrect:

"Please complete this form and give up your details at the desk."

✓ Correct:

"Please complete this form and fill in your details at the desk."

Give up means quit or surrender in this use; it does not mean supply. Because many multi-word verb meanings are difficult to predict from their individual parts, verify the exact entry and example rather than substituting a familiar particle.

Terminology and Sourced Boundaries

Cambridge's multi-word verb guide distinguishes phrasal verbs (verb + adverb particle), prepositional verbs, and phrasal-prepositional verbs. It also documents pronoun placement, longer-object preferences, unpredictable meanings, and the fact that phrasal verbs are often—but not always—less formal than single-word alternatives.

The British Council's phrasal verb lesson uses the broader classroom label for separable and non-separable multi-word verbs. Its word-order guide confirms that personal pronouns split separable verbs, objects follow prepositional forms, and keeping the verb and particle together is preferred when the noun object is long or structurally complex.

🔗 Label the Pattern, Not Just the Phrase

References do not all use phrasal verb at the same breadth. This page identifies Cambridge's narrow category when terminology matters and uses multi-word verb for the wider family.

🎯 Test Your Knowledge

1. Pick the correct order:

2. "Give up" means to ____.

3. Which is correct?

4. "Put off" the meeting means to ____ it.

5. Is "the plane took off" transitive or intransitive?

Live Check: Phrasal Verb Word Order

On July 16, 2026, the exact pronoun-order error below and its revision with turn it off both returned no issues in the local checker.

Expected correction: Could you please turn it off before you leave?

The no-issue result did not validate the word order. British Council and Cambridge guidance requires the personal pronoun between turn and off, so the writer must apply that entry-specific pattern manually.

Frequently Asked Questions

What counts as a phrasal verb?

Cambridge uses phrasal verb narrowly for a main verb plus an adverb particle, such as turn off. Some learner materials use the label more broadly for related multi-word verbs, including prepositional look after and three-part come up with. Check the source's terminology and the verb's object pattern.

What is the difference between separable and inseparable word order?

With separable turn off, a noun object can follow the particle or split the phrase, but a personal pronoun must go in the middle: turn it off. With prepositional look after, the object follows the preposition: look after them.

What did the checker do with the tested turn off sentence?

On July 16, 2026, both Could you please turn off it before you leave? and the revision Could you please turn it off before you leave? returned no issues. The writer still had to apply the pronoun-position rule manually.

How should I check an unfamiliar multi-word verb?

Use a current learner's dictionary to check its meaning, whether it takes an object, and where that object can go. Record the verb with an example instead of assuming that every verb follows the same pattern.

Are phrasal verbs always informal?

No. Cambridge says phrasal verbs are often, but not always, less formal than a single-word alternative. Choose the expression that fits the meaning, audience, and required register.

Real-World Examples

💼 Business:

We had to put off the launch.

Put off = postpone (separable).
🗣️ Daily:

I ran into an old friend downtown.

Run into = meet by chance (prepositional in Cambridge's classification).
🏠 Daily:

Can you look after the dog this weekend?

Look after = care for (prepositional in Cambridge's classification).
✈️ Travel:

The flight took off an hour late.

Take off = leave the ground (intransitive).
📝 Daily:

Please fill out the application.

Fill out = complete (separable).
💪 Daily:

Don’t give up so easily.

Give up = quit (intransitive here).
❌ Common Mistake:

Please hand in it by Friday.

Wrong: "hand it in" (pronoun must split).
❌ Common Mistake:

I came my parents across in the photos.

Wrong: "came across my parents" (inseparable).

A Four-Step Multi-Word Verb Audit

  1. Confirm the meaning. Look up the complete expression, not only the main verb.
  2. Check the object. Record whether this use is transitive or intransitive.
  3. Check the position. For a transitive use, note whether a noun can split the phrase and where a personal pronoun must go.
  4. Check the register. Compare any single-word alternative in context; do not assume it is automatically better or required.

Then test the complete sentence. A no-issue checker result can still miss an entry-specific object-position error.

Multi-word verbs are learned with their meaning and complement pattern, much like the pairings in do vs make. Build the wider verb foundation in what is a verb.
