This paper applies quantitative measures of productivity to a selection of Maltese derivational affixes borrowed from Italian/Sicilian. The productivity rankings of the selected affixes are compared to their Italian sources revealing identical rankings for the most productive affixes and slightly deviating rankings for the less productive affixes. It is argued that morphological productivity scores and the subsequent rankings form a pattern that is established in the recipient language by the sum of matter borrowings of formations involving the respective affixes. In conjunction with a discussion of the mixed lexicon and morphology of Maltese, a case is made that converging or diverging productivity rankings can be explained by well-studied variables in language contact studies: intensity of contact, availability of registers/repertoires, and route of borrowing (direct/indirect). In addition it is shown that the cross-linguistic application of other quantitative measures, including a newly proposed Integration Factor and Seifart’s criteria for direct and indirect borrowing, can help uncover where the distributions of donor and recipient language affixes diverge, providing an exploratory tool for morphologist and contact linguists alike.

本文将生产率的定量度量应用于从意大利/西西里人借来的马耳他衍生词缀的选择中。将所选词缀的生产力排名与其意大利来源进行比较，从而发现最高生产力词缀的排名相同，而生产力较低词缀的排名略有偏差。有人认为形态生产力得分和随后的排名形成了一种模式，这种模式是在接收者语言中通过涉及各个词缀的地层物质借入的总和而建立的。结合对马耳他语的混合词库和形态的讨论，可以得出这样的结论：可以通过对语言接触研究进行深入研究的变量来解释生产率排名的趋同或不同：联系强度，登记册/库的可用性，和借贷途径（直接/间接）。此外，还表明，其他定量措施的跨语言应用，包括新提议的整合因子和赛法尔特对直接和间接借贷的标准，可以帮助发现供体和受方语言缀词的分布在哪里出现差异，从而为探索性工具提供了帮助。形态学家和接触语言学家都一样。
