Long-distance dependencies have been the object of much theoretical interest in the Scandinavian languages and in general, but the empirical foundation for theorizing has been limited. The present paper investigates extraction from complement and adverbial clauses in Danish using acceptability judgment and reading-time measures. Extraction from adverbial clauses was found to be rated near the bottom of the scale and to be associated with a processing cost. This was also true of extraction in adverbial clauses in semantically cohesive sentences, which Jensen (2001a, 2001b) has suggested is acceptable. It is concluded that under the conditions investigated extraction from adverbial clauses in Danish is associated with a processing cost and very low acceptability ratings, despite semantic cohesion.
