My textbook says this:
Be careful with word order when using phrasal verbs. The verb and particle cannot be separated:
- when it is a three-part phrasal verb
I caught up with Jack further down the road.
- if the phrasal verb is used intransitively (without an object)
All my hard work paid off.
- when the particle is a preposition
Sally jumped at the chance of visiting Rome.
I'm confused because I thought this last topic was always true.
When is a phrasal verb not followed by a preposition?
All the phrasal verbs I can remember use a preposition.
