The article discusses the interpretation of expressions in Persian like ketāb metāb in upward-entailing and downward-entailing contexts, where they have a conjunctive vs. a disjunctive interpretation, 'book(s) and/or book-like objects.' It discusses several theories to account for this interpretation, in particular the exhaustification analysis of Smith (2020), a recursive exhaustification analysis similar to Bowler (2014), and homogeneity analyses based on Magri (2014) and Križ (2015). We argue for an analysis that assumes both the conjunctive and disjunctive interpretation, with a preference for the most informative meaning, following the strongest meaning hypothesis of Dalrymple et al. (1998).
