The use of Italian morphology was examined in 34 children ranging in age from 2;6 to 5;0. By the age of 3;6-4;0, high percentages of use in obligatory contexts were seen for a number of grammatical morphemes. Children age 2;6-3;0 showed percentages of use that were somewhat lower than those seen for the older children. In this age range, singular forms were used with higher percentages in obligatory contexts than plural forms, for several different types of grammatical morphemes. Greater control over singular forms in these younger children was corroborated by data from a comprehension task. Even at the younger ages studied, use of grammatical morphemes did not seem influenced by whether phonological cues to agreement were present, or whether the grammatical morphemes were homonymous. Percentages for grammatical morphemes in the form of free-standing morphemes were somewhat lower than percentages for morphemes taking the form of inflections, suggesting that the obligatory nature of inflections in Italian may be a more influential factor than the amount of morphological information contained in a grammatical morpheme.
对34名年龄在2岁6个月至5岁的儿童使用意大利语形态的情况进行了研究。到3岁6个月至4岁时，许多语法语素在强制性语境中的使用率很高。2岁6个月至3岁的儿童的使用率略低于年龄较大的儿童。在这个年龄范围内，对于几种不同类型的语法语素，单数形式在强制性语境中的使用率高于复数形式。一项理解任务的数据证实了这些年龄较小的儿童对单数形式有更好的掌握。即使在研究的较年轻年龄段，语法语素的使用似乎也不受一致性语音线索是否存在或语法语素是否同音的影响。以独立语素形式出现的语法语素的百分比略低于以屈折形式出现的语素的百分比，这表明意大利语中屈折形式的强制性可能比语法语素中包含的形态信息数量更具影响力。
