Concealed questions (CQs) are DPs interpreted as questions when they are complements of question-embedding verbs, such as Kim knows the capital of Vermont or Leslie has forgotten the price of milk. This paper proposes two new semantic answers to the question of CQ distribution. First, it shows that predicates are not idiosyncratic in terms of CQ-embedding, but that a question-embedding predicate can embed a concealed question if and only if it can embed a proposition. Second, it demonstrates that there are two different kinds of CQ with somewhat different distributions.
