Critically assessing underspecification and ambiguity positions, this article presents an argument against underspecification coming from van der Sandt's approach to presupposition as anaphora and questions the need for distinguishing underspecified representation as a separate stage in utterance interpretation on the one hand, and replaces van der Sandt's admittance of some degree of ambiguity of presuppositional anaphora with a scale of salience of possible anaphors on the other.
