This paper offers a comprehensive discussion of the cardinal numeral system of Italian Sign Language. At the lexical level, we present the different formational strategies used to generate cardinal numerals and we provide evidence that in the younger generations of signers, the signonehas lost the function of indefinite determiner and is now used as a cardinal only. At the syntactic level, we show that the attested variation in the ordering between the cardinal and the noun is in part due to definiteness and contrastive focus. We account for this variation within the cartographic approach to syntax. Finally, we offer a principled explanation for the reason why cardinals inside Measure Phrases are not subject to word order variation, but always precede the measure noun.

关于意大利手语（LIS）的基本系统

本文对意大利手语的基数系统进行了全面的讨论。在词汇层面，我们展示了用于生成基数的不同构架策略，并且我们提供了证据表明在年轻一代的手语者中，符号一失去了不定限定词的功能，现在只用作基数。在句法层面，我们证明了基数词和名词之间的顺序变化部分是由于确定性和对比焦点。我们在语法制图方法中考虑了这种变化。最后，我们提供了一个原则性的解释，为什么小节短语中的基数不受词序变化的影响，而总是在小节名词之前。
