 Van der Sandt’s theory incorporates the notion of accommodation as follows. Presuppositions, according van der Sandt, introduce information that prefers to be linked to discourse referents that are already available in the hearer’s representation of the discourse, and in this respect they are like pronouns. Van der Sandt in fact uses the term "binding" to refer to configurations in which presuppositions have antecedents in the Discourse Representation Structure (DRS), thus generalizing the standard notion of a bound pronoun to cases involving multiple discourse referents. However, if a suitable discourse antecedent is not available, a new one will be accommodated, and the presupposition is linked to that. Generally speaking, accommodation is not an option in the interpretation of pronouns, and one reason that has been suggested for this is that a pronoun’s descriptive content is relatively poor (see Section 5.1 for discussion). Being told that “she” is wonderful is not particularly helpful if it isn’t clear who the pronoun is meant to refer to. By contrast, if the speaker refers to “Pedro’s sister” there is more to go on, and accommodation becomes feasible. Hence, van der Sandt hypothesizes that pronouns are a special class of presuppositional expressions: while all presupposition triggers prefer to be linked to antecedents, pronouns almost always must be linked to antecedents because they are descriptively attenuated, and therefore cannot be construed by way of accommodation.
