This article offers an overview of comparative syntactic research covering the Scandinavian languages in the last couple of decades. Most of this research has been conducted within Principles-and-Parameters theory, mostly its Government-Binding phase, and a brief outline of theoretical developments in the 70’s leading up GB theory is included. Comparative Scandinavian syntax research is exemplified both by studies contrasting Scandinavian languages as a whole with English, by studies examining contrasts between Insular and Mainland Scandinavian, and finally with regard to some internal Mainland Scandinavian differences.
