a word order strategy for externally headed - relative clause constructions in which the relative clause, rather than being adjacent to the external relative clause head (either prenominal or postnominal), instead follows the entire matrix clause. Example: I found a linguistics book in a used bookstore last week [that I have been looking for for years] is an instance of the extraposed strategy: the relative clause that I have been looking for for years does not immediately follow the external relative clause head a linguistics book, but instead follows the entire matrix clause I found a linguistics book in a used bookstore last week. (Section 19.2.4)
