The paper takes as its point of departure a comparison between two kinds of approaches to clause structure, namely tree analyses like the generative analysis (as in e.g. Principles & Parameters or Minimalism) and field analyses like the sætningsskema analysis of Danish of Diderichsen (1946) and many others (or like the topologische Modell analysis of German of Drach 1937 and many others). A number of similarities and differences between the approaches will be discussed, in particular the concepts of movement, constituent structure and c-command.
