This study focuses on the acquisition of subject-verb agreement in Brazilian Portuguese. A quantitative analysis of the data produced by a Brazilian child between the ages of 3;02.07 and 3;04.08 is presented. The overall error rate is low. However, a further and more detailed analysis reveals important contrasts both in the frequency of production of different verb inflections (as regards the person/number variables within the verb morphological system) and in the rate of subject-verb agreement errors associated with them. Our findings not only suggest that subject-verb agreement may be acquired piecemeal, but also that the learning of particular verb inflections may itself be a gradual process. Alternatives to the idea of rule-governed production--such as the child's reproducing frozen subject-verb strings previously produced by adults and blending different frozen strings into novel combinations--are discussed as processes which can shed some light on the pattern of both erroneous and correct production shown by this child.
本研究聚焦于巴西葡萄牙语中主谓一致的习得。呈现了对一名3岁2个月零7天至3岁4个月零8天的巴西儿童所产出数据的定量分析。总体错误率较低。然而，进一步更详细的分析揭示出，在不同动词词形变化的产出频率（就动词形态系统中的人称/数变量而言）以及与之相关的主谓一致错误率方面，都存在重要差异。我们的研究结果不仅表明主谓一致可能是逐步习得的，还表明特定动词词形变化的学习本身可能也是一个渐进的过程。作为可以阐明该儿童所表现出的错误和正确产出模式的过程，我们讨论了与规则支配产出这一观点不同的替代观点，比如儿童重现成年人之前产出的固定主谓搭配，并将不同的固定搭配组合成新的形式。
