intransitive three-word phrasal verbs: look forward to, catch up with
3.111 Most phrasal verbs consist of two words: a verb and an adverb, or a verb and a preposition. However, some phrasal verbs consist of three words: a verb, an adverb, and a preposition. This type of verb is sometimes called a phrasal-prepositional verb.

phrasal verbs in questions and relative clauses
3.115 There is one way in which a preposition that is part of a phrasal verb behaves differently from an ordinary preposition.
Normally, when the object of a preposition is put at the beginning of a question or a relative clause, it can be preceded by the preposition, especially in formal speech or writing. For example, you can say From which student did you get the book? and the document on which he put his signature.
However, if the preposition is part of a phrasal verb, it cannot be put before its object in such structures. You have to say What are you getting at? not At what are you getting?, and the difficulties which he ran up against not the difficulties against which he ran up.
Who were they laughing at?
