Abstract In this paper I examine certain gradable adjectives in Serbian, whose suppletive comparative forms display unexpected semantic properties. In particular, while these adjectives are ambiguous between intersective and non-intersective readings in the positive form, their suppletive comparative and superlative forms are limited to the non-intersective interpretation. These facts show, I argue, that in a theory like Distributed Morphology either adjectival roots or category-assigning heads they combine with come in semantic subtypes (i.e. are specified for certain semantic properties; Harley 2005, Anagnostopoulou and Samioti 2014). I show how the analysis I propose explains semantic properties of change-of-state verbs derived from these adjectives and why these adjectives are restricted to the intersective interpretation when their positive form takes the long-form (definite) inflection. I also provide an illustration of how Arregi and Nevins’s (2014) analysis of the so-called “disuppletive” roots, such worse/badder, can deal with the facts presented in this paper. Finally, I discuss implications of these facts in the context of Bobaljik’s (2012) approach to suppletive comparative morphology.

（非）相交形容词和词根补充

摘要在本文中，我研究了塞尔维亚的某些可分级形容词，其形容词比较形式具有意想不到的语义特性。特别是，尽管这些形容词在正向形式的相交和非相交阅读之间是模棱两可的，但它们的补充比较和最高级形式仅限于非相交解释。我认为，这些事实表明，在像分布式形态学这样的理论中，形容词根或类别指称头将它们结合在一起会出现语义子类型（即为某些语义属性指定； Harley 2005，Anagnostopoulou和Samioti 2014）。我将展示我提出的分析如何解释从这些形容词衍生的状态变化动词的语义特性，以及为什么当这些形容词的正形采用长形（确定）形变时，为什么这些形容词仅限于相交解释。我还提供了一个示例，说明Arregi和Nevins（2014）如何分析所谓的“无用”根源，例如更糟/更糟，可以处理本文中提出的事实。最后，我在Bobaljik（2012）的补充比较形态学方法的背景下讨论了这些事实的含义。
