Same but different

In this paper, we argue that same is fundamentally different from different, in thatsame imposes a discourse condition on eventualities, while different compares individuals. This difference has not been noted in previous literature. Furthermore, in the literature on same, there has been a persistent puzzle about the contribution of the definite article with whichsame must co-occur. We show that this puzzle is resolved once the contribution of same is adjusted to apply to eventualities: then the definite article can be interpreted in the usual way, as generating a presupposition about individuals.
