In this article a proposal is made for the treatment of a construction which is known under the terminus "verschränkte Konstruktion" (Kvam 1982); it includes the so called "third construction". The uniform syntactic treatment of topicalisation and the filling of the focus-position in the middlefield corresponds to the functional similarities of both positions. The focus is the part of the sentence which can contain the new information (Geilfuß 1991) and the filling of the focus-position ("Fokussierung") is a means to make prominent a certain part of the sentence with the background of common information in the discourse of speaker and hearer. It is proposed in this article that the constructions in question are not-coherent in the sense of Bech (1983).
