The two goals of this paper are (i) to establish that there are comparative correlatives that are not comparative conditionals and that the semantics of such correlatives crucially involves a relation (possibly the identity relation) between differentials (against much of the previous literature, e.g., McCawley 1988, Beck 1997 and (ii) to argue that a unified analysis should be given for such non-conditional, differential-based comparative (and equative) correlatives and the more familiar, conditional-like comparative correlatives.Correlatives are "biclausal topic-comment structures [. . . ] [in which] the dependent clause introduces one or more topical referents to be commented on by the matrix clause, where each topical referent must be picked up by -correlated withan anaphoric proform." (Bittner 2001). Differentials, e.g., 2 cm in the comparative Gabby is 2 cm taller than Linus, specify the difference between two measures, e.g., between Gabby's and Linus's heights.
Non-Conditional Comparative and Equative CorrelativesThe first point is established by the existence of comparative correlatives with overt than-phrases (which are usually not acceptable in English) like the one in (1) mother.the 'The brother is taller than the sister by a certain amount and the father is taller than the mother by the same amount.' Intuitively, sentence (1) is true iff (i) the brother is taller than the sister and the father is taller than the mother, that is, there is no conditionality (no'if the brother is taller than the sister . . . ' kind of interpretation), and (ii) the difference in height between the brother and the sister is the same as the difference in height between I am grateful to Daniel Altshuler, Pranav Anand, Rajesh Bhatt, Cleo Condoravdi, Sam Cumming, Donka Farkas, Simona Herdan, Slavica Kochovska, Sophia Malamud, Megan Moodie, Roumyana Pancheva, Asya Pereltsvaig, Octavian Popescu, Jessica Rett, Ivan Sag, Oana Sȃvescu, Roger Schwarzschild, two SALT XVIII reviewers and the 9 th Stanford Semantics Fest and SALT XVIII audiences for comments and / or data and / or judgments.
