Co-constructing meaning is acommon feature of all conversationsbut may have amore specific role in interactions where one of the participants uses aided communication. The present study applies qualitative descriptive analysis supported by quantitative measures in exploring meaning-negotiation strategies of speaking communication partners in task-related aided conversations. The study focuses on identifying and exploring strategies that the communication partners utilise when attempting to interpret the meaning and resolve potential ambiguities of aided utterances in the context of event descriptions. The participants of the study were three aided communicators (age 8 to 11 years), who used graphic communication systems as their main means of communication, and familiar adult communication partners. The results demonstrate that the communication partners employed several strategies in attempting to comprehend, interpret and co-construct the meaning of aided utterances at various phases of interaction. The primary strategy involved clarifying the lexical properties of the aided constructions, reflecting the multidimensional and polysemous nature of graphic communication systems. Structural and referential complexities affected how the elements produced were understood as part of the ongoing context. The study highlights the participants´ shared responsibility in developing and utilising effective meaning-negotiation and repair strategies to support successful communication.
