Two-part verbs: prepositional verbs
verb + preposition: listen to; look at
Many English verbs are regularly followed by prepositions before objects.
- You never listen to me. (not
You never listen me.) - Luke walked down the road without looking at anybody.
Prepositions are not used when there is no object.
- Listen! (not
Listen to!)
Idiomatic meanings: look after, get over
The meaning of a prepositional verb can be very different from the meanings of the two parts taken separately.
- Could you look after the kids while I’m out? (Look after is not the same as look + after.)
- He took ages to get over his illness. (Get over is not the same as get + over.)
Word order: What are you thinking about?
When an object comes at the beginning of a clause (e.g. in a question or relative clause), a prepositional verb usually stays together, so that a preposition can be separated from its object and go at the end of the clause. For details of this and other preposition-final structures, (see here).
- What are you thinking about? (not
About what are you thinking?) - I’ve found the book which I was looking for. (More natural in an informal style than ... the book for which I was looking.)
Verbs with prepositions and particles together
A few verbs can be used with both an adverb particle (see here) and a preposition (making them three-part verbs).
- I get along with her quite well.
- Stop talking and get on with your work.
- It’s hard to put up with people who won’t stop talking.
- If you’re on the road on Saturday night, look out for drunk drivers.
- I’ll think about it and get back to you.
- She went up to the officer and explained her problem.
- I’m looking forward to the party.
