We argue that definite noun phrases give rise to uniqueness inferences characterized by a pattern we call definiteness projection. Definiteness projection says that the uniqueness inference of a definite projects out unless there is an indefinite antecedent in a position that filters presuppositions. We argue that definiteness projection poses a serious puzzle for e-type theories of (in)definites; on such theories, indefinites should filter existence presuppositions but not uniqueness presuppositions. We argue that definiteness projection also poses challenges for dynamic approaches, which have trouble generating uniqueness inferences and predicting some filtering behavior, though unlike the challenge for e-type theories, these challenges have mostly been noted in the literature, albeit in a piecemeal way. Our central aim, however, is not to argue for or against a particular view, but rather to formulate and motivate a generalization about definiteness which any adequate theory must account for.

确定性投影

我们认为定名词短语会引起唯一性推论，其特征是我们称之为定性投影的模式。确定性投影表示，除非在过滤前提条件的位置中存在不确定的先例，否则确定性的唯一性推论就会突出。我们认为，定性投影对（定）定性的e型理论构成了严重的困惑；在这样的理论上，不定式应该过滤存在的前提，而不是唯一性的前提。我们认为，确定性投影也给动态方法带来了挑战，尽管难以实现，但动态方法难以生成唯一性推论并无法预测某些过滤行为，尽管这些挑战与电子类型理论的挑战不同，但大多数都是在文献中指出的，尽管它们是零星的。但是，我们的主要目标不是主张或反对特定观点，
