ABSTRACT
A concept developed by Koster (1986) in Government and Binding theory, whereby prototypical local domains can be extended on the basis of language-specific or lexical factors to less local domains. This makes possible grammatical relations outside the prototypical local domain. The so-called bridge verbs are domain-extending for movement transformations. For example, in Whoi do you think Philip saw t1, the object can be questioned out of the embedded clause.
