A constraint on preposition sequences in English complex predicates

This paper makes two main arguments. First, I show that certain V + P + P constructions with a verb and two intransitive prepositions are constituents involving a sequence of verb and two small clauses that together constitute a complex predicate. Second, after noting that the first P is restricted to the preposition back, I then argue that this restriction stems from back's unaccusative status that allows adjunction of the second PP to back's internal argument position. A preposition like through does not permit such an adjunction because its sister position, if phonetically expressed, must be an object DP.

► The paper argues that certain V + P + P sequences in English can be analyzed as complex predicates.
► When two prepositions appear in such a sequence the first must be back.
► This constraint follows from back being unaccusative.
