What are Separable and Inseparable Phrasal Verbs?
Phrasal verbs consist of a verb + particle (preposition or adverb). A key feature is whether they can be separated by an object.
- Separable: The object can come between the verb and the particle.
- Inseparable: The verb and particle must stay together.
Understanding this difference is crucial for correct sentence structure.
1. Separable Phrasal Verbs
With separable phrasal verbs, the object can be placed in two positions:
- After the particle.
- Between the verb and the particle.
Can you turn down the music?
Can you turn the music down?
Both sentences are correct and have the same meaning.
Common Separable Phrasal Verbs:
call back, fill in, give back, pick up, put on, take off, turn on/off, try on
The Pronoun Rule
This is very important: If the object is a pronoun (me, you, him, her, it, us, them), it MUST go between the verb and the particle.
| ✓ Correct | ✗ Incorrect |
|---|---|
| Please pick me up at 8 PM. | Please pick up me at 8 PM. |
| She put it on quickly. | She put on it quickly. |
| Turn it off before you leave. | Turn off it before you leave. |
2. Inseparable Phrasal Verbs
With inseparable phrasal verbs, the verb and particle always stay together. The object must come after the particle.
I'm looking for my keys.
(Incorrect: I'm looking my keys for.)She gets on with her colleagues.
(Incorrect: She gets on her colleagues with.)
Common Inseparable Phrasal Verbs:
look after, look for, get on with, run out of, wait for, come across
Tip: Most three-part phrasal verbs (verb + adverb + preposition) are inseparable.
I'm looking forward to the weekend.
3. How to Know if a Phrasal Verb is Separable or Inseparable?
Unfortunately, there are no simple rules. The best way is to pay attention to how they are used and to check a good dictionary when you are unsure. Most dictionaries will tell you if a phrasal verb is separable.
For example, a dictionary entry might look like this:
pick sb/sth up (This shows it is separable)
look for sth (This shows it is inseparable)
Common Errors and How to Fix Them
| ✗ Incorrect | ✓ Correct | Why |
|---|---|---|
| I will call back you later. | I will call you back later. | When the object is a pronoun, it must go between the verb and particle for separable phrasal verbs. |
| She is looking after her bag. | She is looking for her bag. | This is a meaning error. Look after = take care of. Look for = search. Both are inseparable. |
| He asked out her. | He asked her out. | Ask out is separable, and with a pronoun object, the pronoun must go in the middle. |
| Let's talk the problem over. | Let's talk over the problem. | Talk over can be separable, but it's more common to keep it together when the object is long. Both are technically correct, but one is more natural. |
Summary
| Type | Rule | Example |
|---|---|---|
| Separable | Object can go in the middle or at the end. | Take your shoes off. / Take off your shoes. |
| Separable (Pronoun) | Pronoun object MUST go in the middle. | Take them off. |
| Inseparable | Verb and particle MUST stay together. | I'm looking for my shoes. |
💡 The key takeaway: Always remember the pronoun rule for separable verbs. It's one of the most common mistakes for learners. When in doubt, check a dictionary!
