Abstract At the heart of this special issue are partitive elements (i. e., partitive articles, partitive pronouns, and partitive case markers) which can express different “shades” of partitivity, namely true partitivity, pseudopartitivity, or indefiniteness, that is, the absence of a part-whole relation in the meaning, in contrast to (pseudo)partitivity. Since these partitive elements express (at least) two such notions, as they can be truly partitive but often are not, the questions around partitivity are complex, interrelated and challenging. This special issue, with a strong and wide crosslinguistic (typological) coverage, deals with two overarching topics: first, the geographical distribution of partitive elements and the identification of potential instances of language contact, and, second, sometimes in combination with the first topic, the formal description and explanation of different partitive constructions.

简介：参与性阴影：形式和区域属性

摘要这一特殊问题的核心是构成要素（即构成要素，构成代词和构成格标记），它们可以表达不同的组成性“阴影”，即真正的组成性，伪组成性或不确定性，即不存在与（伪）分性相反，意义上的整体关系。由于这些参与性要素（至少）表达了两个这样的概念，因为它们可以是真正的参与性，但往往不是，因此，关于参与性的问题是复杂，相互关联且具有挑战性的。本期特刊涵盖了广泛而广泛的跨语言（类型学）主题，涉及两个总体主题：第一，组成要素的地理分布和识别语言接触的潜在实例，第二，有时与第一个主题结合使用，
