ABSTRACT This article aims to analyze the process of mutual understanding from the perspective of Discursive Neurolinguistics. As a methodology, a case study was carried out on a child with a linguistic profile of verbal restriction, which concerns the dimension of utterances involving words and their morphology. Data interpretation was based on the Bakhtinian perspective, which addresses ‘understanding’ as an active-responsive process and meaning as emerging from the relationship between utterances. The results showed that the interlocutors’ common ground allowed the (...) joint construction of meaning even in the face of verbal restrictions, and aspects such as nonverbal elements and the recognition of the child’s active-responsive role also favored mutual understanding. As a conclusion, the attention to different multimodal resources as legitimate modes of expression allows children with verbal restrictions to fulfill the role of “speakers” regardless of their modes of expression.
