Building on previous works which argued that scalar implicatures can be computed in embedded positions, this paper proposes a constraint on exhaustification (an economy condition) which restricts the conditions under which an exhaustivity operator can be licensed. We show that this economy condition allows us to derive a number of generalizations, such as, in particular, the ‘Implicature Focus Generalization’: scalar implicatures can be embedded under a downward-entailing operator only if the (relevant) scalar term bears pitch accent. Our economy condition also derives specific predictions regarding the licensing of so-called Hurford disjunctions.

经济和嵌入式穷竭

在先前认为可以在嵌入位置中计算标量蕴含量的工作的基础上，本文提出了对穷竭性的限制（经济条件），该约束条件限制了穷举性操作员可以被许可的条件。我们证明了这种经济条件使我们能够得出许多概括，例如“隐含焦点概括”：只有在（相关的）标量项带有音高重音的情况下，标量含义才能嵌入到向下的运算符下。我们的经济状况还得出有关所谓的赫尔福德析取项许可的具体预测。
