In this new book, well-known linguist Guglielmo Cinque takes a generative perspective on typological questions relating to word order and to the syntax of relative clauses. The articles gathered in the first part of the present volume deal with word order, while the second address relative clauses. In particular, Cinque looks at: the position of the Head vis a vis the relative clause in relation to the position of the verb vis a vis his object; a general cross-linguistic analysis of correlatives; the need to distinguish a sentence-grammar, from a discourse-grammar, type of non-restrictives (with languages differing as to whether they possess both, one, the other, or neither); a selective type of extraction from relative clauses; and a tentative sketch of a more ample work in progress on a unified analysis of externally headed, internally headed, and headless relative clauses.
