This series consists of collected volumes and monographs about specific issues dealing with interfaces among the subcomponents of linguistic structure: phonology-morphology, phonology-syntax, syntax-semantics, syntax-morphology, and syntax-lexicon. Recent linguistic research has recognized that the subcomponents of grammar interact in non-trivial ways. What is currently under debate is the actual range of such interactions and their most appropriate representation in grammar, and this is precisely the focus of this series. Specifically, it provides a general overview of various topics by examining them through the interaction of grammatical components. The books function as a state-of- the-art report of research.

Syntactic complexity has always been a matter of intense investigation in formal linguistics. Since complex syntax is clearly evidenced by sentential embedding and since embedding of one clause/phrase in another is taken to signal recursivity of the grammar, the capacity of computing syntactic complexity is of central interest to the recent hypothesis that syntactic recursion is the defining property of natural language. In the light of more recent claims according to which complex syntax is not a universal property of all living languages, the issue of how to detect and define syntactic complexity has been revived with a combination of classical and new arguments. This volume contains contributions about the formal complexity of natural language, about specific issues of clausal embedding, and about syntactic complexity in terms of grammar-external interfaces in the domain of language acquisition.
