I’ll throw it away. Take them off.
We can’t put an adverb between the verb and particle or between the particle and object:
* I paid the loan back early. (not: I paid early back the loan. / I paid back early the loan.)
We can’t put a relative pronoun immediately before or after the particle:
* That’s the room which I did up. (not: That’s the room which up I did. / That’s the room up which I did.)
3) These phrasal verbs take an object, but we cannot separate the verb from the particle. These phrasal verbs are
called prepositional verbs (verb + preposition)- look into, look for, look at.

Sue takes after her mother. Looking after a baby is hard work.
We put the object (noun / pronoun) after the preposition and not between the verb and preposition (compare
with the second type):
* We didn’t fall for it / his story. (not: We didn’t fall his story for. / We didn’t fall it for.)
4) These phrasal verbs have three parts: a verb + particle + preposition. We cannot separate the verb from the
other parts. These verbs can be made passive:
* All her employees looked up to her. (active)
* She was looked up to by all her employees. (passive)
I’m looking forward to the weekend.
You go now and I’ll catch up with you later.
§ Phrasal verbs form tenses, and are used in questions and negatives and in the passive voice, in the same way as other verbs:
* Will you be putting the party off? * The party has been put off until next month.
§ We never separate the verb and the particle in the passive form:
* That story was made up by a resentful employee.
§ We can sometimes form nouns from multi-part verbs:
* The car broke down five kilometers from home. (multi-part verb)
* The breakdown happened five kilometers from home. (noun)
