Two-part verbs: phrasal verbs
verb + adverb particle: get back, walk out
Many English verbs can be followed by small adverbs (‘adverb particles’). These two-part verbs are often called ‘phrasal verbs’.
- Get back!
- She walked out.
- I switched the light off.
Common adverb particles: about, across, ahead, along, (a)round, aside, away, back, by, down, forward, in, home, off, on, out, over, past, through, up.
Some of these words can also be used as prepositions. Compare:
- I switched the light off. (adverb particle)
I jumped off the wall. (preposition)
For a detailed comparison, (see here).
Idiomatic meanings: break out; turn up
The meaning of a phrasal verb is often very different from the meanings of the two parts taken separately.
- War broke out in 1939. (Broke out is not the same as broke + out.)
- Joe turned up last night. (= ‘appeared’—not the same as turned + up.)
- I looked the word up in the dictionary. (Look up is not the same as look + up.)
- We put off the meeting till Tuesday. (Put off is not the same as put + off.)
Phrasal verbs with and without objects
Some phrasal verbs are intransitive (they do not have objects).
- I got up at 7.00 today.
- That colour really stands out.
Others are transitive.
- Could you switch the light off?
- I helped Anna to clean up the room.
Word order with objects
Adverb particles can go either before or after noun objects (unlike most adverbs). (see here)
- She switched off the light. or She switched the light off.
But they can only go after pronoun objects.
- She switched it off. (not
She switched off it.) - Is that the light which you switched off? (not ...
the light off which you switched?) - Give me back my watch. or Give me my watch back. (not
Give back me my watch.)
