Book excerpt: The book discusses the information structure approach as introduced by the Prague linguistic circle and elaborated, in the first place, by Jan Firbas, one of the key persons in the field of functional sentence perspective (FSP), and further by Aleš Svoboda, Libuše Dušková or Martin Adam. It explores the Norwegian existential construction from the syntactic and FSP points of view but also discusses selected FSP aspects in general. The theory of functional sentence perspective has been attested to multiple languages such as Czech, English, German, Russian, French, Italian or Spanish. This book attempts, among other things, to attest its applicability to Norwegian, and thus demonstrate its universal nature, at least in the field of Indo-European languages.
