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)
