The volume demonstrates the interdependence of man’s language capacity and his other conceptual capacities. This enables linguistic structures to be minimalised, and for extra-linguistic domains to provide much of the interpretations of sound and meaning. Underspecification is demonstrated in the word formation of Indo-European, Late Archaic Chinese and modern Khmer; on the word- and sentence levels by the event structures of German; and in the information structure predominantly of languages with the so-called free word order: German, Slavic languages, Arabic compared with English and the tone language Hausa. The volume is noteworthy due to the close cooperation between theoretical and experimental research. Within grammar, it has especially strengthened prosodic research and the syntax-phonology interrelations and their interpretations, and it has helped to create data bases for the relations within texts and to evaluate the findings.
