According to a prominent theory of disjunction, the modal in ‘John is away, or he must be in his office’ has its domain restricted by the negation of the left disjunct ‘John is away’. However, in ‘John has to write a paper, or he will get a C’, the right modal is not restricted by the negation of the entirety of the left disjunct but instead by the negation of the prejacent of the left disjunct. We dig into the empirical pattern of this flexibility of restriction and propose a new theory of disjunction.
