On non-conservativity of Korean floating quantifiers

Since the Conservativity Universal (Barwise & Cooper 1981; Keenan & Stavi 1986) has been proposed for natural language determiners, several apparent counterexamples have been presented in the literature. Some of these, such as English only in Only students presented, have been argued to involve an adverbial structure, thus not violating Conservativity. In this paper, we focus on proportional quantifiers such as 70% in Korean, which have been shown to have a non-conservative reading when floated out of the DP (Ahn & Sauerland 2017). While Ahn & Sauerland (2017) assume that floated quantifiers are adnominal, Korean floated quantifiers have been shown to have both adnominal and adverbial variants (Ko 2014), thus leaving open the possibility that the non-conservative reading is simply resulting from an adverbial structure, like only. We test out the predictions of the adnominal and the adverbial accounts of non-conservative quantifiers in Korean. Our results show that floating quantifiers in non-conservative contexts a) cannot be definite-marked, and b) cannot be intervened by a vP-internal (low) adverbial, both of which are predicted if the non-conservative quantifier is adnominal, but not if it is adverbial. Based on these findings, we conclude that the non-conservative proportional quantifiers in Korean involve adnominal floating quantifiers. Our study thus makes a novel case for the claim that syntactic movement can be implicated in order to explain a non-conservative construal of a quantifier in languages under the Conservativity Universal.
