 In order to determine the intended meaning of “the author”, the hearer has to infer (i) that there is an author and (ii) that the said author wrote the book read by John. Whereas on a broad understanding of accommodation, all of this is accommodated, on a strict construal only (i) is, and (ii) is a bridging inference. This is not just a matter of terminology. If we choose to be strict, we can argue that there is something like an “accommodation module”, which as such has nothing to do with world knowledge; whereas if the notion is construed more broadly, accommodation is of a piece with bridging. To facilitate the following discussion, we will adopt a strict notion of accommodation, and take the naive view that what is accommodated is the presupposition as triggered by, e.g., a definite NP or factive verb.
