Russian Disjunction To li To li and Obligatory Ignorance

In this paper, we explore the behavior of one complex disjunction in Russian that has some special properties that set it apart from other simple and complex disjunctions: it never gives rise to free choice inferences in environments in which other disjunctions do and under universal quantifiers it behaves different from other disjunctions. We show that the data resist an analysis in terms of wide scope disjunction and propose that those special properties are due to obligatory ignorance inferences associated with this disjunction. The paper provides one more argument for a grammatical theory of ignorance along the lines of ( 7).
