Complex hierarchic syntax is a hallmark of human language. The highest level of syntactic complexity, recursive-embedded clauses, has been singled out by some for a special status as the evolutionary apex of the uniquely - human language faculty - evolutionary yet mysteriously immune to Darwinian adaptive selection. Prof. Givón's book treats syntactic complexity as an integral part of the evolutionary rise of human communication. The book first describes grammar as an adaptive instrument of communication, assembled upon the pre-existing platform of pre-linguistic object- and-event cognition and mental representation. It then surveys the two grand developmental trends of human language: diachrony, the communal enterprise directly responsible for fashioning synchronic morpho-syntax and cross-language diversity; and ontogeny, the individual endeavor directly responsible for acquiring the competent use of grammar. The genesis of syntactic complexity along these two developmental trends is compared with second language acquisition, pre-grammatical pidgin and pre-human communication. The evolutionary relevance of language diachrony, language ontogeny and pidginization is argued for on general bio-evolutionary grounds: It is the organism's adaptive on-line behavior- invention, learning and skill acquisition - that is the common thread running through all three developmental trends. The neuro-cognitive circuits that underlie language, and their evolutionary underpinnings, are described and assessed. Recursive embedding turns out to be not an adaptive target on its own, but the by-product of two distinct adaptive moves: (i) the recruitment of conjoined clauses as modal operators on, or referential specifiers of, other clauses; and (ii) the subsequent condensation of paratactic into syntactic structures.

Complex hierarchic syntax is considered one of the hallmarks of human language. The highest level of syntactic complexity, recursive-embedded clauses, has been singled out by some for a special status as the apex of the uniquely-human language faculty – evolutionary but somehow immune to adaptive selection. This volume, coming out of a symposium held at Rice University in March 2008, tackles syntactic complexity from multiple developmental perspectives. We take it for granted that grammar is an adaptive instrument of communication, assembled upon the pre-existing platform of pre-linguistic cognition. Most of the papers in the volume deal with the two grand developmental trends of human language: diachrony, the communal enterprise directly responsible for fashioning synchronic morpho-syntax; and ontogeny, the individual endeavor directly responsible for the acquisition of competent grammatical performance. The genesis of syntactic complexity along these two developmental trends is considered alongside with the cognition and neurology of grammar and of syntactic complexity, and the evolutionary relevance of diachrony, ontogeny and pidginization is argued on general bio-evolutionary grounds. Lastly, several of the contributions to the volume suggest that recursive embedding is not in itself an adaptive target, but rather the by-product of two distinct adaptive gambits: the recruitment of conjoined clauses as modal operators on other clauses and the subsequent condensation of paratactic into syntactic structures.

The volume examines syntactic complexity from an acquisitional perspective, which offers a peculiarly grounded starting point when dealing with linguistic complexity, under the assumption that what is simpler is acquired earlier than what must be thought of as complex. Connecting acquisitional data inseparably to formal linguistic analyses, it not only allows a comparison between structures at various levels in terms of complexity, but also a deeper insight into the factors determining complexity in different populations of acquirers. The book is divided into two parts following an introductory chapter. The papers in Part I consider the first language acquisition of some complex structures such as different types of passives, relative clauses, questions and classes of predicates, with a look at children’s early sensitivity to seemingly complex domains, such as the Definiteness Effect and unaccusative predicates. Part II is dedicated to the acquisition of complex structures in different modes of acquisition. The papers here examine, sometimes comparatively, different conditions of language acquisition dealing with clitics, types of relative clauses or referential pronouns. The languages considered range from European Portuguese to Finnish, French, German, Italian and Romanian.

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.

This volume surveys the phenomenon of syntactic complexity in a diversity of languages and from a diversity of theoretical perspectives. The topics include clause combining strategies such as relative, complement, and adverbial clauses, serialization, clausal nominalizations, but also the switch reference systems involved in clause chains, the role of insubordination and the influence of language contact in the development of syntactic complexity as well as the acquisition of complex clauses in child language and the grammaticalization processes leading to syntactic complexity. These studies illustrate the varied aspects involved in clause combining and help to understand how syntactic complexity works and evolves in the world’s languages, how it varies across languages, how it is influenced by language contact, how it is acquired. As such, this book gives the opportunity for readers to expand both their typological and their theoretical knowledge about syntactic complexity in a variety of languages.

This book is about dynamical, social-interactional aspects of the emergence of complexity in language, explained by linguists, cognitivists, and modelers.
