Dutch is an official language in the Netherlands, Belgium-Flanders, Surinam, Aruba and the Netherlands Antilles. With about 22 million native speakers it is one of the world?s greater languages. It is taught and studied at more than 175 universities around the world (source: taalunieversum.org). Furthermore, Dutch is one of the most well-studied living languages; research on it has had a major, and still continuing, impact on the development of formal linguistic theory, and it plays an important role in various other types of linguistic research. However, much information is hidden in scientific publications that are mainly of interest for and accessible to certain groups of formal linguists or that are more or less outdated in the light of more recent findings and theoretical developments, and more material is buried in publications with only a limited distribution or which are simply inaccessible to large groups of readers because they are written in Dutch. The series Syntax of Dutch (SoD) therefore aims at providing a comprehensive scientifically based description of the syntax of Dutch that is accessible to a wider international audience. For similar phonological and morphological descriptions the reader is referred to taalportaal.org (which also contains the complete SoD and similar descriptions of Frisian and Afrikaans).
