In 1989, a group of members of the Copenhagen Linguistic Circle, inspired by the advances in cognitive linguistics and the functionalist theories of Simon C. Dik founded the School of Danish Functional Grammar aiming to combine the ideas of Hjelmslev and Brøndal, and other important Danish linguists such as Paul Diderichsen and Otto Jespersen with modern functional linguistics. Among the prominent members of this new generation of the Copenhagen School of Linguistics were Peter Harder, Elisabeth Engberg-Petersen, Frans Gregersen, Una Canger and Michael Fortescue. The basic work of the school is Dansk Funktionel Grammatik (Danish Functional Grammar) by Harder (2006).
