This paper presents an analysis of Danish free relative constructions. Fol- lowing Bresnan and Grimshaw (1978) we will adopt a wh-head (in Danish hv-head) analysis where the hv-phrase is the head of an NP. Also following Bresnan and Grimshaw (1978) we will propose an analysis which does not involve a filler-gap dependency between the hv-phrase and the gap in the sis- ter clause. Instead we will propose that the gap in the sister clause is bound off by a constructional constraint. In this way the analysis will be shown to differ from previous HPSG wh-head analyses of free relatives.
