Derivation or Representation? Hubert Haider & Klaus Netter 1 The Issue Derivation and Representation - these keywords refer both to a conceptual as well as to an empirical issue. Transformational grammar was in its outset (Chomsky 1957, 1975) a derivational theory which characterized a well-formed sentence by its derivation, i.e. a set of syntactic representations defined by a set of rules that map one representation into another. The set of mapping rules, the transformations, eventually became more and more abstract and were trivialized into a single one, namely "move a" , a general movement-rule. The constraints on movement were singled out in systems of principles that ap ply to the resulting representations, i.e. the configurations containing a moved element and its extraction site, the trace. The introduction of trace-theory (d. Chomsky 1977, ch.3 §17, ch. 4) in principle opened up the possibility of com pletely abandoning movement and generating the possible outputs of movement directly, i.e. as structures that contain gaps representing the extraction sites.
