 Van der Sandt’s theory accounts for these observations as follows. We suppose that the grammar assigns (43) the intermediate semantic representation in (44a). Here [ u1,…, um: φ1,…,φn] is a simple Discourse Representation Structure in linear form, with u1,…, um a list of discourse markers, and φ1,…,φn a list of conditions on those markers; connectives like ⇒ are used to build up complex conditions. We assume for convenience that most interpretative problems have been cleared out of the way already, and that the only thing that remains to be done is resolve the presuppositions triggered by “his”, “his son” and “too”, which are flagged by Beaver’s (1992) trigger symbol, ∂.
