The binding theory incorporates the notion of accommodation as follows. Presuppositions, according to the theory, introduce information that prefers to be linked to discourse referents that are already available in the DRS, and in this respect they are like pronouns. However, if a suitable discourse referent 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 a possible reason for this is that a pronoun’s descriptive content is relatively poor. 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, the binding theory views pronouns as a special class of presuppositional expressions. While all presupposition triggers prefer to be bound, pronouns almost always must be bound. According to the binding theory, this is because pronouns are descriptively attenuated, and therefore cannot be construed by way of accommodation.
