This paper considers the relationship between synchronic variation and language change in the context of the existential and possessive constructions in Modern Hebrew, which exhibit a normative – colloquial alternation. The study examines usage patterns across age groups and time periods, as represented in spoken-language corpora. It shows that the non-normative construction is used extensively in the contemporary speech of adults. Moreover, a comparison of the use of the normative – colloquial alternations by two populations, children and adults, in different time periods, provides evidence to suggest that these constructions are undergoing language change. A cross-linguistic perspective lends additional support: across languages the expression of existence involves non-canonical structures, which are particularly susceptible to language variation and, possibly, language change.

现代希伯来语中的存在和所有格

本文在现代希伯来语的存在和所有结构的背景下考虑了共时变异与语​​言变化之间的关系，这些结构表现出规范-口语交替。该研究检查了不同年龄组和时间段的使用模式，如口语语料库所示。这表明非规范结构在当代成年人的言语中被广泛使用。此外，在不同时期，儿童和成人这两个群体对规范-口语交替使用的比较提供了证据表明这些结构正在经历语言变化。跨语言的观点提供了额外的支持：跨语言，存在的表达涉及非规范结构，
