On the semantics of Korean modalized question

The goal of the current study is to suggest a novel paradigm of epistemic modal operator originated from the disjunction. Our main data is Korean disjunction operator nka which forms a non-factual question. Examining how the modal effect in question is induced by nka, I propose that the prerequisite of nka brings about non-homogenous nonveridical (i.e. modal) spaces partitioned in equipoised epistemic spaces, thus there is no bias between them. I furthermore show how the distinct notions of disjunction, question, and possibility modal can be captured under the theory of nonveridical equilibrium (Giannakidou 2013, Giannakidou and Mari 2016).
